Review: Excellent Representation of Your Audio Media - I’ve been using Audio Technica AT50’s since 2004 and MSR7’s for about 3 years. The 50’s are great for bass heavy music and the MSR7’s are (I thought) great for detailed acoustic, vocal, percussion and other 1khz and higher audio. I don’t know what my expectations were with the Sennheiser HD650’s. All I knew for sure is that I have read countless reviews and articles where they are used as reference headphones. Whether as the focus of the written material, or in passing as the gear reviewers use when auditing or reviewing other equipment and music/media. The HD650’s are universally accepted as a reference headphone. So over the last several years they have sparked my curiosity. I ordered them and received them within 2 days. I am a classic rock aficionado, and have my own set of reference tracks that I use when trying out new equipment in my home studio. I’ve played guitar and drums for 35 years (not expertly, but passable?). I have a nice Roland Kit, a couple of nice Fender and Mesa Boogie Tube Amps, Fractal Axe FX III guitar processor and run it all through various digital I/O and microphones into an RME UFX+ Audio Interface. The RME interface has an excellent ADC/DAC configuration, with a very clean sound at the headphone jack that matches the outputs on the other analog outputs on the interface, but is also amplified. They didn’t cut corners. All of this is to say that I have great reference hardware, knowledge of good source media, and the headphone amplifier and DAC section from my audio interface surpasses most high end audio AVR’s. Now generally, like most folks these days, I listen to rather low end compressed MP3 audio. It’s readily available and doesn’t take up storage space. As storage space has become less expensive, I’ve started to record and save my audio in the highest quality format my interface will allow. Generally that is a minimum of 16bit 320kbps compressed, or as high as 24bit 96khz, with maximum playback capability of 24 bit/192kHz. All the detail. The things that you didn't even know were buried in the mix. The 3 second harmonies, the double tracks that are barely distinguishable, the finite exquisite breath of the vocalist as they prepare for the next line of the verse. All laid out in stunning depth and form. Strange things that you didn’t even know were in the mix, that add depth and character to the music, that are underneath the main harmony and melody of the music. Things that only an explorative and creative genius of a producer would include in the mix and final mastering. Dark Side of the Moon takes on a new landscape. Steely Dan Aja highlights perfection of studio recording at it's finest. You can get lost for hours in old recordings and hear the things that you didn't even know made the music that you enjoy so enjoyable. Edit: As an aside, I need to include something extra ordinary. Something that I would presume that maybe 1/10th of 1% of folks who actually purchased these headphones would pursue. An opportunity to audit the HD650’s via an RME ADI-2 PRO FS BE AD/DA. The RME unit is in the Top 3, or arguably is the best, mastering quality DAC and by far the best headphone amp that money can buy. Period. No exceptions. Numbers don’t lie and RME’s audio engineering team is among the finest on the planet and can back them up. The UFX+, as I mentioned, is no slouch at all. They perform tremendously in the studio, and the quality of the gear DOES shine through during headphone testing. Blissful. But…. When you listen to anything through the ADI-2, it’s clichéd to say, but it really is not just “next level”. It’s the very “top level”. That said. You have now reached a level of clarity that some people might actually find slightly uncomfortable believe it or not. The lack of distortion is unfamiliar and with poorly recorded or or media compressed with a bad encoder, the flaws shine. Too much so occasionally. On the other hand. With good to exceptional media, and phones like the HD650 that can convey expertly produced media, you will be sitting at the control desk, where the mastering engineer was sitting. Hearing everything (and maybe more) than they were hearing as they put the final touches on the song or album. I have yet to audition what are considered to be be “better” headphones. Maybe someday I’ll get a chance to A/B the HD650’s against another premium set. Until then I remain blown away by the Sennheisers. If you’re here trying to decide if you should pull the trigger on these. It is simply a resounding YES! Keep in mind that these are 300 Ohm headphones. They will require more power than your iPhone, or Android phone to fully appreciate their capabilities. You do not need a $1000 headphone amp to enjoy them. Their are several headphone amps/Pro level DAC’s from $200 to several thousand dollars that will all do the job. I highly recommend that you are able to drive them with an output of greater than 100mW minimum. Just my opinion. Do what you will. But you will not be able drive any kind of realistic bass below that threshold. Yes, people around you will hear them. But you are buying open back headphones for a reason. Your listening enjoyment. Find a place to disappear and enjoy them and turn it up. I highly recommend these headphones. They are simply incredible.
Review: Heavenly sonic bliss. Achievable even on an iPod without amplifier. - HD 650 Heavenly sonic bliss. My favorite headphone. Full rich, lush sounding voices and instruments. Widest sound stage of my headsets with excellent clarity. Very easy to separate and follow various voices and instruments in the music I listen to. Very balanced across the entire range of frequencies without one range over powering another. Everything is very clear. No muddiness of sound. Cybals and chimes crisp and clear. Snare drums nice crisp sound. Bass pleasant with excellent sound decay and appropriate reverberation lasting longer than my other headsets. I can really feel the music around my ears with this headset. The sound envelopes my head instead of feeling like its between my ears. Now I can experience the music rather than just listen to it. Makes music much more enjoyable and realistic sounding. This can be driven by my iPod, iPad, MacBook Pro, Laptops and Desktop PCs without an amplifier. I have no doubt an amplifier will improve the sound, but the sound is already rich and clear without amplification and still better than my other headphones. I'm hearing/experiencing things that I never heard before with my other headsets ... the faint pops that occur from an old LP that has been digitally recorded ... just amazing (from an iPod without amplifier). This is my experience. Your mileage may vary depending upon what you want out of your headsets. Finding the “best headphone" is a very expensive and very subjective journey. Reading reviews can only take one so far. Opinions range far and wide depending upon the reviewers individual tastes, experience with music and what one primarily listens to. Descriptions of the sound in reviews don't always help due to differences in meaning. For example what is described as the veiled Sennheiser sound may be what I call a mellow laid back sound (not sure). My advise is listen to your music with a lot of different headphones and do your own comparisons to determine what you like. What you hear coming from each headphone is going to vary with the design of the headphone, but also modulated by a. the type of music you listen to b. how the recording was originally made (microphones converting analog to electrical then stored on magnetic tape or digitized) b. the quality of the recording you are listening to (especially if digitized, what was truncated if anything) c. the format in which it is recorded and sampling rate d. the equipment you play it on and how it translates the recording back to an electrical impulse to be sent to the headphone e. the headphones themselves (open, closed, type of diaphragm material, how many speakers (i.e. the Shure 500 series has 2 woofers and a tweeter in each ear piece to achieve its balanced sound presentation across its spectrum, I have a gaming headset with multiple speakers) Having said that, the music I listen to is classical to 60s, 70s, 80s, 90s, pop, country, jazz, big bands, vocals, instrumentals. I don’t have a dedicated amplifier and play all my headphones on iPods, iPads, iPhones, Mac Book Pros, PCs, Pioneer Tuners. All my headphones sound just fine without an amplifier, but I have no doubt that an amplifier will improve the sound. My music is recorded in MP3 at 320 kbps, but I prefer M4A apple lossless or WAV at 1400 kbps for the best possible digital sound quality. I can hear the difference between 1400 kbps, 320 kbps, and the more compressed music at 192 and 128 which can be found on MP3 sites like the apple store. I convert my CD collection to both 1400 kbps and 320 kbps 44.1 MHz so it can be played at the best quality on whatever system I am using. All my headphones have been broken in with at least a 72 hour continuous play run. My headphones from most favorite to least favorite are Sennheiser HD 650 Shure 500PTH Sennheiser HD 598 AKG K550 Sennheiser HD 555 modified to 595 Sony DLP777 — bright Jaybird Spirit — midtones muffled due covering that prevents sweat getting into ear pieces Sennheiser HD 280 Noise cancellers: Bose QC2 — bass heavy, muddy midtones Bose QC3 — even more bass have, muddy midtones Dr. Dre Beats — too bass heavy, stick to rap and non-critical listening (rap) For me, the HD 650 is a 5 star headphone and by far my favorite of all my headphones. Allows me to truly feel and experience the music I like listening to using the devices I have. My iPods, iPhone, iPads and MacBook Pro can drive this 300 ohm just fine (of course the volume level has to be turned up compared to the lower ohm headphones), but the lush rich realistic sound still comes through better than the other headphones. By feel, I mean that the HD650 diaphragms move so much air around my ears I can feel and experience the music as opposed to just hearing it. The Shure PTH500 can do this in my ear canal. My HD598 does this much better than the HD 555 and has a more pleasant sound to me than the HD555. But none of these come close to the experience I get with my new HD650. It’s like standing in front of a speaker at a concert or DJ’d party except its around me ears instead of having my body feel the sound wave. The timbre, tone, character of the instruments from the HD650 is slightly better than my original reference PTH500. PTH500 and HD650 are better than my other headsets. With these two, I discovered things that I couldn’t hear with the other headsets. Sound stage of the HD650 is wider than the PTH500 which is wider than the other headphones. Both have much better separation of the instruments and vocals and much better clarity which gives the music a more 3 dimensional enjoyable sound. Much easier to pick out individual instruments and so I can more easily play along on piano, guitar etc. With other headsets I have to struggle to hear the individual parts. The Shure 500 has been my favorite reference headphone since 2008. With its sound isolation qualities, I use it when traveling and when I don't want to disturb others around me. The problem with it is that it can eventually be painful on the ear canals and sound quality (bass) is lost when the ear canal seal is lost when moving around or exercising. Additionally, hearing the crunch of food while eating and listening with the 500s is a consequence of in ear monitors. Both the HD650 and PTH500 have the best balance across all sound frequencies with the widest sound stage. The Bose QC2, QC3, and Beats have more emphasis on bass followed by treble at the expense of midtones, so if I want really loud bass, I’ll go with the Beats followed by QC3, then QC2 for lesser degrees of bass punch. The HD 598 was my favorite after the PTH500 because its open design moves a lot of air allowing me to kind of feel the music, but not the extent of the HD650. It has what I consider a more laid back and mellow sound than the HD 555 and PTH500. Kinda relaxing and pleasant. HD555 DLP777 place more emphasis on treble. If I want high energy treble, the HD555 and AKG K550 are my go to headsets. I prefer the open design over the closed headsets because they just move air better with a generally richer sound then my closed headphone Shure 500PTH — best overall balance and 3D clarity while physically blocking outside noise HD 598 -- open, good overall balance, mellow sound AKG 550 — closed, good overall balance. doesn't move air as well as HD598, but good second choice to the 598 HD 280 — closed thin; waste of my money. was never happy with it. Sony MDP 777 — closed, emphasis on treble Bose QC2 — closed moderate bass. muddy midtones Bose QC3 — closed heaviest on bass. muddy midtone So my choices for headsets boil down to Best overall sonic experience: HD650 Best outside noise reduction/isolation and overall sonic experience: Shure 500 series Best to minimize noise spill into the surrounding environment when I can’t use the Shure 500: AKG 550 Best for heavy bass emphasis: In order from least bass to intense bass: Bose QC2, QC3, Dr. Dre Beats Ultimately the “best” headset is a subjective opinion depending upon what you want to hear and/or experience out of your music. There is a huge sliding scale of perceived quality. I wouldn’t recommend spending much on an expensive headset if your music is 128 kbps compressed. But then again, it is cheaper to just buy 1 headset and grow into it rather than spend lots of money working ones way up to the holy grail of headsets. If I knew then what I know now, I would have just bought the HD650 and stopped there.

## Questions & Answers

**Q: Are they better than beats?**
A: For all the Beats haters out there, they're not the overworked, bass heavy, poorly made headphones the other snobby answers seem to make them out to be.

I own these Sennheiser 650 cans. I also own the Audio Technica 50 that many others seem to drop in the answers to this question.

Truly the answer is to each his own. To be fair, it's important to compare Beats and these while hard wired, ideally into a headphone amplifier. 

Once you listen to Beats hard wired like these or other high quality headphones, you'll quickly realize Beats are no dollar store wannabes.

Funny, but if you like listening to Dr. See or Snoop, you may like the Beats more, I know I do on occasion.

These are reference quality headphones that really aren't for everyone. They do not hit the bass very hard, the highs are not accentuated, and for those audiophiles reading this, the sound stage is wide open on this Sennheiser 650, while the Beats is tighter, more enclosed, tuned to rap or metal or electronic music.

You may find these lacking if you're used to headphones tuned for more emphasis as opposed to replicating audio as recorded in the studio.

These are amazing headphones no doubt, but you must have the right equipment, starting with a solid headphone amplifier. Beats simply need a Bluetooth connection. 

I hope this more balanced answer helps those trying to decide on their next headphones.

**Q: how do these compare to the hd 598's**
A: I just did a back-to-back test of these two headphones today (I own the 598's). The 650's sound better. They have an incredibly natural-sounding reproduction. It's.... perfect. The problem with the 598's is an over-emphasized mid-low area which in layman's terms would seem muddy. Also, the high's have a bit of sizzle, which is common among dynamic headphones, especially AKG's (also tested out their whole range today). The 598 holds it's own amongst other headphones in the 200-500 dollar range, but the HD 650 is in a class by itself.

**Q: Does it support/ us it on android phone?**
A: The 650-s have 300 ohm impedance. This  makes them not the best option for an Android or Iphone  handheld. 
For that application, you are better off with a lower impedance headset, e.g: the HD 585  is 150 ohms, the 280/300 series  is 62 ohms.   The 280-s are closed back, and excellent for listening using a mobile device.  The HD-650 will be rather quiet directly connected to an Android phone. 
The 650 maybe overkill listening to compressed content, as it is common on mobile devices.   The typical use scenario for these is connecting them to a high quality source (often, driven by a hi-resolution player, playing Flac or Dsd or some other high resolution material), using a headphone amp.   I own the MassDrop version (the HD6XX), and I also have an older HD-555, and the HD-555 is a better experience plugged into my LG android phone, streaming "high quality" spotify.

**Q: Can they be used effecively on an airplane?**
A: The 650's are not noise cancellation headphones and inferior to Bose, for instance, when using on a plane. In addition the 650's can be heard by others because of the open design. They are superior to everything else for solo listening when you are not on a plane.

I convert my CD collection to both 1400 kbps and 320 kbps 44.1 MHz so it can be played at the best quality on whatever system I am using. All my headphones have been broken in with at least a 72 hour continuous play run. My headphones from most favorite to least favorite are Sennheiser HD 650 Shure 500PTH Sennheiser HD 598 AKG K550 Sennheiser HD 555 modified to 595 Sony DLP777 — bright Jaybird Spirit — midtones muffled due covering that prevents sweat getting into ear pieces Sennheiser HD 280 Noise cancellers: Bose QC2 — bass heavy, muddy midtones Bose QC3 — even more bass have, muddy midtones Dr. Dre Beats — too bass heavy, stick to rap and non-critical listening (rap) For me, the HD 650 is a 5 star headphone and by far my favorite of all my headphones. Allows me to truly feel and experience the music I like listening to using the devices I have. My iPods, iPhone, iPads and MacBook Pro can drive this 300 ohm just fine (of course the volume level has to be turned up compared to the lower ohm headphones), but the lush rich realistic sound still comes through better than the other headphones. By feel, I mean that the HD650 diaphragms move so much air around my ears I can feel and experience the music as opposed to just hearing it. The Shure PTH500 can do this in my ear canal. My HD598 does this much better than the HD 555 and has a more pleasant sound to me than the HD555. But none of these come close to the experience I get with my new HD650. It’s like standing in front of a speaker at a concert or DJ’d party except its around me ears instead of having my body feel the sound wave. The timbre, tone, character of the instruments from the HD650 is slightly better than my original reference PTH500. PTH500 and HD650 are better than my other headsets. With these two, I discovered things that I couldn’t hear with the other headsets. Sound stage of the HD650 is wider than the PTH500 which is wider than the other headphones. Both have much better separation of the instruments and vocals and much better clarity which gives the music a more 3 dimensional enjoyable sound. Much easier to pick out individual instruments and so I can more easily play along on piano, guitar etc. With other headsets I have to struggle to hear the individual parts. The Shure 500 has been my favorite reference headphone since 2008. With its sound isolation qualities, I use it when traveling and when I don't want to disturb others around me. The problem with it is that it can eventually be painful on the ear canals and sound quality (bass) is lost when the ear canal seal is lost when moving around or exercising. Additionally, hearing the crunch of food while eating and listening with the 500s is a consequence of in ear monitors. Both the HD650 and PTH500 have the best balance across all sound frequencies with the widest sound stage. The Bose QC2, QC3, and Beats have more emphasis on bass followed by treble at the expense of midtones, so if I want really loud bass, I’ll go with the Beats followed by QC3, then QC2 for lesser degrees of bass punch. The HD 598 was my favorite after the PTH500 because its open design moves a lot of air allowing me to kind of feel the music, but not the extent of the HD650. It has what I consider a more laid back and mellow sound than the HD 555 and PTH500. Kinda relaxing and pleasant. HD555 DLP777 place more emphasis on treble. If I want high energy treble, the HD555 and AKG K550 are my go to headsets. I prefer the open design over the closed headsets because they just move air better with a generally richer sound then my closed headphone Shure 500PTH — best overall balance and 3D clarity while physically blocking outside noise HD 598 -- open, good overall balance, mellow sound AKG 550 — closed, good overall balance. doesn't move air as well as HD598, but good second choice to the 598 HD 280 — closed thin; waste of my money. was never happy with it. Sony MDP 777 — closed, emphasis on treble Bose QC2 — closed moderate bass. muddy midtones Bose QC3 — closed heaviest on bass. muddy midtone So my choices for headsets boil down to Best overall sonic experience: HD650 Best outside noise reduction/isolation and overall sonic experience: Shure 500 series Best to minimize noise spill into the surrounding environment when I can’t use the Shure 500: AKG 550 Best for heavy bass emphasis: In order from least bass to intense bass: Bose QC2, QC3, Dr. Dre Beats Ultimately the “best” headset is a subjective opinion depending upon what you want to hear and/or experience out of your music. There is a huge sliding scale of perceived quality. I wouldn’t recommend spending much on an expensive headset if your music is 128 kbps compressed. But then again, it is cheaper to just buy 1 headset and grow into it rather than spend lots of money working ones way up to the holy grail of headsets. If I knew then what I know now, I would have just bought the HD650 and stopped there.

### ⭐⭐⭐⭐⭐ All my life I hate headphones, because I couldn't listen to them longer ...
*by A***R on February 13, 2018*

All my life I hate headphones, because I couldn't listen to them longer period of times in ear canal ones were piercing my brain over on ear ones were uncomfortable with side effects my ears were sweating itching. Experience made me refuse buy any headphones over the decade because I've always felt they not worth it. Other hands I have quite old vintage Pioneer Hi-Fi Speakers which is my uncle bought in 80's. They still sounds great but only goes to frequency response 28 KHZ max. I have approximately 105 SACD ripped them to DSD ( Sony DSF) format with my old PS3, sacd ripper, Also Around 203 Hi-Res albums ( 24 BIT) which my friends & I bought shared through different online stores like ( Hdtracks, Qobuz, Hiresaudio.com etc). Rest of my collection just Redbook 16 bit 44.1 khz lossless format ), I haven't decent DSD native decoding DAC I'm using Macbook Pro 15. ( 2016) this device Audio capabilities garbage it has Cirrus Logic DAC muddy which only goes 96 khz, line out from this device only limited 48 khz max feeding this device through line out to amp to speakers were awful experience everything sounds muddy instruments sound separation, soundstage nothing is presents Hi-Res Audio sounded worth than CD etc. I have before Sony SACD player it laser head malfunctioned after 8 years of Use & went bad 8 years ago. After this thing broken from different laptops even expensive Apple Macbook Pro audio experience was worst I've experienced so far. I knew I need some sort of USB Audio Advanced DAC something to convert my DSD files Natively & Hi-Res Audio max out of resolution doesn't make sense have 24 bit 192 khz lossless file when your device DAC only can reproduce 96 khz can only output 48 khz max so you got my point. I have proper DAC now which Capable Play DSD ( 64,128) natively PCM up to 384 khz & line out headphone out not limited to 48 khz anymore it is alo headphone amp which have specs 285 mv ( 32 Ohm) 2.9 volt. 1. Sennheiser HD 650 Comfort ----------- I would give 10/10 never used anything like this before, you can listen for longer periods without getting any fatigue or discomfort they also very well breathable, I'm using this about 5-6 hours without break I've never got tired this is so big advantage this headphones have over others & what make them so special best in their class ( Note they have little clamping force in beginning when they are new but this thing easily resolved after 4 days of Use I left them on position Clamping Box 10 cm distance from each drives 4 days all day & this clamping pressure has gone) 2. Sennheiser HD 650 Sound Quality & Resolution ----------- Second batch of this product which is currently Amazon.com selling have frequency response up to 10 - 41.000 hz ( Hi - Res Audio Certified By Japan Audio Society) it has sticker on box, Sound quality resolution everything crystal clear bass in there ( Mids Vocals I've never heard anything like this they are magical & very straight forward & intimidate this headphones only woth buying just for listening female vocals they sounds so precious nothing come close this kind of quality this cans providing in this regard), Highs many others would say veiled actually I'm not agree with that they very well represented they just not piercing this is one of the magic formula which makes listen to this headphones long listen sessions without getting tired. 3. Sennheiser HD 650 -Power Requirement DAC, Amplification, Source ------------- This headphones rated 300 ohm, Power requirement for this I'm not 100 % sure but checked online headfi.org other online 3 volt 500 mv - 32 ohm, everyone says they incredible scales with powerful amp. I'm currently using them with my 2.9 volt 285 mv on 30 ohm source they driving this in required level so they sounds incredible, I've not t feeding them all 500 mv by now I don't own so powerful headphone amp yet. I bet with powerful amp they even getting better. Of Course Source material DAC also matters it will help get better results in the end. Currently my source 1200 ( 16 bit 44.1 khz albums lossless format), 105 DSD SACDS, 203 Hi-Res 24 Bit ( 44.1 khz up to 192 khz files) 150 albums I have in ITunes format 256 kb/s ACC, In my listening best sounding is DSD, 2nd place 192 khz PCM, 3 rd place Redbook CD 16/44.1, worst sounding AAC 256 kb/s . During listening sessions I'm more often trying avoid this ACC albums. So source matters as well to get full more detailed refined experience. 4. Sennheiser HD 650 - value build quality --------------- This headphones lightweight for it own class so you couldn't expect this thing being build from any metal it have metal where durability matter Driver Grills made from metal headband clamping sides made from metal, rest of the Unit it is high quality plastic. If you take a good care about your equipment I didn't think it will be broken anytime soon some people using HD 600 now over 15 years & nothing got broken during this time except pads & cable this is normal. This thing Made In Europe Ireland how many items do you own last 2 decades made in Europe ? Trust me build quality it is top notch. For 374.99 $ this headphones is steal. This is 500 $ valued headphones for the resolution comfort this thing provide I don't think they overpriced, nowadays any sub par Sony or Other HI-RES headphones costing 250 $ forget about bluetooth other futures every other headphone have sound quality through wireless option worst indeed, still best option connection for optimal sound quality is wire. Audio Software Used for testing Audio Nirvana Plus full version only available by this moment only ON MAC OS costing 74.99 $, It is bitperfect software have Lots of Audio futures & excellent sound quality 10 times better what average ITUNES sounds like, Native DSD playback, advanced metadata editing etc. I'm usually not to keen write reviews about products but I then saw some people giving this item sub par scoring one star rating so I decide wrote one. Please don't listen to this people they don't using this headphone as intended. They generally bought it plugged into smartphone jack or laptop, in my experience this headphone I'm not tried my smartphone but from Macbook Pro 15 ( 2016) headphone jack they sound like some cheap 15 $ no name headphone. So Please note ( Source, DAC, proper amp, all this matters to get full out of this headphones)
