Features

Powerful Bass

Specially designed, powerful drivers deliver deep and powerful bass that perfectly complements 

today’s popular music genres.

Direct-Vibe Structure

A tightly sealed acoustic design allows for a high level of sound isolation which aides in the 

reproduction of powerful and extended bass sound.

Extended Comfort

Newly-developed seamless, noise isolating ear pads use pressure relieving urethane foam for not 

only an outstanding fit, but reduced ambient noise.

Slim, Swivel Style

Slim in stature with swivel-fold earpads, Sony MDR-XB400 headphones are lightweight when worn, 

yet easily stow away in a backpack or book bag when on the go.

Tangle-free Cord

The durable, 1.2 m flat cord has a serrated finish that reduces tangles, so you can get caught up 

in your music, not your cord.
