Top build quality.
High build quality, excellent sound although not so much on the highs. Nevertheless very enjoyable.

Sound okay but rather uncomfortable.
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.

Simple earphones modestly priced but reproduce a topical quality of Sennheiser sound. Good product.I would suggest that the lead connections are more robust as they appear to be easily damaged it the plus is not carefully inserted or extracted.

Great audio but uncomfortable
Audio quality was very satisfying and noise cancellation works but after a few uses I noticed the top of my head and ears would hurt after only an hour or two of use. So it's hard to reccomend but it's probably easier if you don't wear glasses.

Sound is incredible
I just got my headphones, and I couldn't be happier! Everything about them is 10 out of 10. The sound quality is good the cable is long enough to listen easily and the forms are so soft for hearing. I highly recommend them to anyone looking for top-notch audio performance!

2 year review: Don't bother.
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.
