Pros: Measured response gives it an excellent Harman preference score of 85 with a 1.21 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. It uses 1 x 10mm dynamic with an easy 18 ohm load.
Cons: Discontinued, so it is mainly found used. Its 1.21 dB spread is less even than the best measured sets.
