This is an on-ear headphone not as marked on the website an over-ear one. Please be more transparent about ear cup size.

The headphone is fairly good. It can effectively isolate the outer sound and the music. However, it is a bit unclear in vocal sound.
Jordan H.
Was expecting better audio quality and build of product. Ear covers were far too small for your average ear size resulting, making them uncomfortable after a very short period of time.
Massimo B.
A good product at an absolutely affordable price. Good Bass and depht of sound. I don't like the small pitch plug inserted in the headphones and the excessively short wire.
Sokreth R.
The size of the head phone doesn't fit with my ears. The sound quality is still not so good.
andy m.
superb headphones. super comfortable. the sound quality is amazing. i really cant emphasize how good the sound is.
Lisa G.
Really great sound quality and quite comfortable. I do wish they were a bit more adjustable though. I find them to be a bit tight on the sides of my head after a while and the way they lengthen doesn't seem to resolve the issue. Also a volume dial on the cord would be a welcome addition!

From delivery, unpacking and final use, these earphones matched and surpassed all expectations. Both my wife and I were in tearing with the depth of sound experienced. Many thanks again.
Andrew S.
Super quality and great sound. Here in 4 days from Germany (including a weekend) with all fees included.

It’s a great experience, but you can add an option in the purchase process. Especially if the buyer is not an EU resident or citizen, in this case there is no need to pay the taxes. You can ask the buyer for a passport copy

I'm not a headphone connoisseur, however, for my needs they work well. Great balanced tone and successfully drowns out the noise of the central line in London.
George C.
Very High quality design and audio quality for the price. Very comfortable, and will last a long time.e
SOURAV D.
Loved the quality of the product.
Serena C.
Price-quality ratio is really recommended.
Low weight and noise reduction ok.

Headphone works fine, good value for money.
The outside noise insulation works great the only downside is the 2.5 jack with the blocking system as it nearly costs a third of the whole set if needed replaced.
Good product anyway

The Sennheiser HD 400S is the right headphones for me. Sound quality is good and the it is affordable. The only downside I could think of is when you wear it for a long time, the top of your head starts to hurt because of how it fits. I would've loved it if the material is kinda flexible. Apart from that, overall is a good buy!

Great value, blocks a lot of noise and sounds great.
