SennheiserHD 400S - Over-Ear Headphone with Smart Remote, Black

I recently bought the Sennheiser 400s, and I’m beyond impressed! The product is exactly as shown in the pictures — 100% original, crystal-clear sound, deep bass, and very comfortable to wear even for long listening sessions. Delivery was super fast, packaging was secure, and communication with the seller was excellent. The seller is extremely professional, honest, and highly recommended. I will definitely buy from this seller again!

Usual Sennheiser quality of build. Sound is good - I will only use these for relaxed listening so don't expect them to be the ultimate in sound quality. Fit is comfortable and the cable is plenty long enough for my use case.

Was looking for a new pair of headphones to use with my Yamaha keyboard. Saw these and they were within my budget. A good fit, and blocks out extraneous background noise effectively (but this is down to their closed-back design - they don't have a noise cancelling feature). Much better build quality than my previous foldable Sony headphones - but you get what you pay for. A good, all round set of headphones for a very reasonable price. Delivered very quickly and excellent service from the vendor. 10/10

The sound is very good and doesn't stray from the radio station, on music it's got a perfect sound and at that price a steal thanks

I have owned these headphones for 2 years, in which time they've seen fairly light use as my portable set that I take on long walks, train journeys etc. I have probably taken them out roughly 15-20 times at most.I have almost nothing positive to say about these headphones. Even before they broke (which I'll get to shortly), it was apparent that they were riddled with design flaws and quality issues.As many other reviewers have noted, comfort is poor. People with larger ears have reported that the openings of the ear cups are quite small and can pinch the ears around the edges. I'm fortunate enough to have ears small enough to fit inside the cups, but still found that the foam around them was a little firm and could cause numbness around my ears after fairly brief periods of time. Worse than this is the headband, which has no padding, just a vaguely flexible rubber strip, and feels like it's cutting into your head after a short while.If you can put up with the discomfort, the plastic of the headphones creaks and groans like an arthritic old man's knees whenever you move your head, and the thudding of your footsteps is also somehow transferred directly into your ears. This is rather intrusive and difficult to ignore, making them poor for journeys and rubbish when walking. Sound quality is a little flat but generally okay for the price, so you can enjoy this as long as you keep perfectly stationary to avoid having it spoiled by the sound of creaking plastic. It's also worth mentioning that the cable is very thin and feels like it could snap easily if it ever got caught in anything.Late last year, the joint of the right cup which allows rotation left and right snapped when taking the headphones off, leaving the cup hanging freely. The joint is so small that I'm surprised it didn't break sooner (I've attemped to show the break in the pictures but the size made it difficult. It's the small, grey looking inner ring inside the hinge). I wrapped it in duct tape as a remedy, which meant that the cup no longer fitted flush with my head. Last week, the same joint broke in the left cup when taking them out of my rucksack. So they have now been unceremoniously binned.I was led to believe that Sennheiser produce headphones of excellent quality at all price points, but these were so poor that I will be avoiding them like ebola for the foreseeable future. They're rubbish for travelling but I can't recommend them for use at a desk either due to the discomfort, nasty plastic creaking and the overall flimsiness of the build.Save your money and find an alternative.

Very good sound with some quality issues. I'd give the sound 8/10 with a rich bass, strong mids and a clear top-end. Separation of instruments and the sound stage is excellent. So all good there. However, the plastic of the headband audibly creaks and the ear pads are uncomfortable for more than 20-30 minutes, as they press on ears which is especially bad if you also wear glasses. It has a completely unnecessary microphone button which means they don't work with audio equipment that requires a 3 pole stereo TRS connector (2 rings).

Always great headphones Last ages & I use them all day at work, never have any problems. Brilliant!!!

Okay as a backup for my Sony noise cancelling phones. They sound okay but I find the earpads on the Sennheiser HD400S headphones to be inadequate for them to be worn for very long. The pads are thin and flimsy so my ears contact the headphones baffle. I also find that they actually become painful to wear after a while, especially as I need to wear spectacles for VDU work.On the other hand they were cheap, so I guess one gets what one pays for. With the latter point in mind, I will give them 4 stars instead of the 3 that was my first thought.Edit: I forgot to mention when I originally posted this review that, when playing games like 'Sniper Elite' on my Playstation, my Sennheiser HD 400S headphones actually reverse the left and right sound channels. A tad confusing, so another reason not to used them for gaming. Okay for music, Spotify and such, I suppose but a bit confusing with games where one needs to be able to hear what’s lurking around the next turn, wall, or whatever. Hopefully this is just my pair of headphones and not a general flaw with this product.
