Short answer: the TRN Jaws. Both are rated 3.6/5 for sound quality (#728 and #714 of 1291 in-ear headphones), and the TRN Jaws costs $129.99 against $137.57 for the Technics EAH-AZ70W, so with nothing between them on sound quality, price settles it.
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.
What the TRN Jaws does well: An eight driver hybrid with three dynamic drivers, four balanced armatures and a planar. The tradeoff: A 2.37 dB spread from the target shows peaks and dips that better tuned sets avoid.
Buy the TRN Jaws. Both are rated the same for sound quality, and it costs $7.58 less than the Technics EAH-AZ70W.
