Pros: It uses 1 x 50mm dynamic with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. A tonal tilt of -2.56 makes it sound dark, with bass well ahead of the treble. Its 5.42 dB spread from the target means a noticeably uneven response. A Harman score of 6 places it in the lower part of the over-ear rankings.
