Review: These IEMS hit all the right spots for me. They have top notch technical capabilities in separation, layering, and resolution, audio reproduction with natural timbre, and a warm-neutral sound signature. Together, these allow the IER-M9s to produce a supremely enjoyable and exquisite listening experience across all genres. Concerning comfort, the preformed ear-hangers and the provided different sized ear-tips keep the IEMs stably perched in my ears with no difficulties. The connection between the cable and the IEM body can swivel, so there should be no issues with awkwardness of positioning of the IEMs. I have found it easy to quickly put on the IEMs and get a good seal (common advice is to pull the lobes of the ears backwards and upwards slightly). These also provide good isolation, having used them on flights (yes, you can't really experience 'audiophile' quality music on a plane, but from experience, they're definitely still significantly better than the Sony WH-1000XM4s and Bose NC700s). For reference, I own the IER-M9s and the Focal Clears (a pair of over-the-ear headphones), and I use them for about ~20h and ~40h a week, respectively, switching to the M9s during the evenings when I typically prefer a warmer sound signature or when I wish to read in bed. These are the priciest personal audio devices I have ever owned (but not the priciest that I have tried), and I have no regrets for either of them. I should point out that I am not too concerned with large soundstages in my devices as I have used IEMs and headphones with larger soundstages in the past and found that I was not impressed with what they did to my music with the exception of orchestral pieces. The M9s also produce a palpable and pleasant rumbling in the sub-bass frequencies (with no strange balanced armature flavoring that I can discern), though they are not considered bass-heavy when compared to other top of the line IEMs. NB: Some readers may not consider the IER-M9s "top of the line". Apologies for the abuse of language.
Review: theres no place where these lack, their built wel, they look great and they come with a lot of accessories. these go very well with spinfit w1 or dunu S&S, render tips are not good at all and azla exlastics sound a bit harsh. the sound is why you buy this, it sound good, very good at times scary good. resolution is good but not the best i've heard anything more than this will sound exaggerated like my ie600 which has more detail which i like but you might not, a very nice very noticeable step up from ier-m7s(i also own) that lacks detail. bass is good but flat, still very accurate and at times enjoyable but never stealing attention, well detailed and good enough texture. mids are great well detailed and placed, treble follows nice detailed and almost never sibilant. THE REASON TO BUY THIS, this iem has the best soundstage i and many others have ever heard as it has directionality to every note specially drums. this also goes for the best Imaging that i and many other have ever head in the product like it , imaging has dept so it sound deep and 3d to the max. the separation and layering is also outstanding. the price is steep but these are truly a great set, hard to drive as well but my phone had no issue running them. just don't forget that this can sound bad with music that isn't mastered correctly.

## Questions & Answers

**Q: Can the sony ier-m9 work with a windows pc using the 3.5 mm connection? would i need other hardware? will there be any audio quality loss if yes?**
A: If you want to use PC as source, I recommend you to buy the RME-ADI 2 FS or Chord Mojo 2. Your PC will send digital signal without noise to Mojo2 or RME and it converts the digital to analog signal cleanly. 
If you plug the headphone directly to 3.5mm, it will tap into the noise from the PC and the 3.5mm does not have enough current to drive the full potential of headphone. You will lose details.

**Q: (sound wise) how does these compare to "wf1000xm4“ or "wh1000xm4" (want quality "branded" wired earbuds everyday use) ?**
A: The sound quality of the IER-M9 is miles ahead. The details, instrument separation, timbre, soundstage and dynamics are simply far better.

**Q: Can these be moved with just an iPhone?**
A: Hi Carlos,

Thank you so much for your interest in our IER-M9 In-ear monitor headphones. If your iPhone supports stereo mini-plug (3.5 mm) connection, yes, it will work.

Thanks again for considering Sony!

- Romeo

**Q: Are these sweat and dust resistant?**
A: I have sweat with these while playing the drums.  I have had no issues.  As far as dust resistant.  I do not know of any headphone/ear-monitor that has ever succumb to dust.  I keep them in the case anyway.  I hope that helps.

I am blown away by these amazing headphones, Bass is unreal, it puts over ear headphones to shame. pair it with a nice Sony Hi-Res player, and use the 4.4 mm Balanced connection for even better experience. highly recommended!
