Aluminum fascia for punchy bass .
These headphones are made for the kind of bass that gets you moving. The light but rigid aluminum fascia on top of the housing suppresses unwanted vibration to preserve deep,punchy, low notes. .

Enfolding closed-back design seals in sound
The closed-back, enfolding design wraps around the ear, sealing in music and keeping out distractions. Acoustics are reflected back toward your ears, so you hear even the subtlest sounds. You also feel every beat, as the closed-back design maximizes the bass signatures in your music. .
High sensitivity for a loud, clear sound
With enhanced sensitivity of 102 dB/mW, these headphones are highly efficient in converting electricity into acoustic signals. This means you&rsquo.ll hear a louder sound across the entire audio spectrum (compared to less sensitive headphones) when listening to music through the same source and at the same volume level.
