What reviewers say

Reviewers agree the headphones are light and practical for DJing, with a clear sound and punchy upper bass. They differ on isolation, which MusicRadar found excellent and RTINGS unimpressive. MusicRadar found the on-ear fit tiring for some and the tuning less suited to mixing; RTINGS noted a plasticky build and rolled-off deep bass.

  • Frequency response of 16 Hz to 22 kHz is narrower than Sennheiser's hi-fi headphones
