Best of the best in most areas, but vocals and mids can be thin due to fit issues. Insane bass texture/detail and HUGE soundstage. One of the best trebles I've heard.

Recessed mids I can't approved but best bass tactility I've heard. One of the best stage I've heard. Top of the class treble. Fit is a massive problem for most - one of those that needs to be demoed before pressing checkout.

Visceral, hard-hitting bass, sparkly treble, and a large, spherical soundstage with impressive height. Fit may pose a challenge for many. Cons: Poor fit.
