Short answer: a tie on sound quality. Both are rated 3.6/5 (#727 and #714 of 1291 in-ear headphones) at nearly the same price ($139 vs $137.57), so choose on features and fit.
Why pick the Kinera Celest Yaksha: A four driver hybrid with two dynamic drivers, a Knowles balanced armature and a micro planar. The catch: Treble sits about 3.0 dB below target, a dark, relaxed balance.
The case for the Technics EAH-AZ70W: Crinacle’s measurement gives it a solid Harman preference score of 69 with a 2.60 dB spread. Watch for: Its 2.60 dB spread is less even than the best measured sets.
Buy the Kinera Celest Yaksha or the Technics EAH-AZ70W on features: they are rated the same for sound quality at close to the same price.
