Pros: Crinacle’s measurement gives it a solid Harman preference score of 69 with a 2.60 dB spread. Its tonal tilt of +0.01 sits close to the target, so the overall balance is neither dark nor bright. It uses 1 x 10mm dynamic. It is truly wireless, so there is no cable to manage.

Cons: Its 2.60 dB spread is less even than the best measured sets.
