Short answer: the Kinera Celest Phoenixcall. Both are rated 3.6/5 for sound quality (#703 and #714 of 1291 in-ear headphones), and the Kinera Celest Phoenixcall costs $129.99 against $137.57 for the Technics EAH-AZ70W, and with sound quality even, the cheaper one is the better buy.
Why pick the Kinera Celest Phoenixcall: The median of 16 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.38 dB spread. The tradeoff: A 6.1 dB peak near 1.5 kHz can make cymbals and sibilance sound sharp.
Why pick the Technics EAH-AZ70W: Crinacle’s measurement gives it a solid Harman preference score of 69 with a 2.60 dB spread. The catch: Its 2.60 dB spread is less even than the best measured sets.
Buy the Kinera Celest Phoenixcall. Both are rated the same for sound quality, and it costs $7.58 less than the Technics EAH-AZ70W.
