Pros: It uses 1 x 10mm dynamic with an easy 16 ohm load. It is truly wireless, so there is no cable to manage.

Cons: A tonal tilt of -3.01 makes it sound dark, with bass well ahead of the treble. Its 6.22 dB spread from the target means a noticeably uneven response. A Harman score of 9 places it in the lower part of the in-ear rankings.
