“I bought these as an upgrade from the W3, which while extremely fun, I soon became disappointed in, due to mid bass bleed into the midrange.

I love their size and weight. They only...” --shotgunshane
“Bass response doesn't bleed to the vocals or any other frequencies whatsoever, lightweight cable with no microphonics and a narrow plug to connect to portable devices.
