Best headphones I've had - all I wanted was some headphones that played high quality sound, no bells or whistles (wireless, volume control etc.); these headphones delivered.

I bought is mainly for music and gaming.
The sound is great. The built materials is good. Loves the ear cup, they are so soft.
It very tight when put on my head at first, you will need to make bit of adjustments and positions the ear cups properly
I am loving this so far!!

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.
