Shure breathes new life into its flagship ANC headphones.
A 3.7 puts its noise isolation / ANC in the bottom quarter of over-ear headphones we've measured.
Measured on 86 of the 240 we've cataloged.
below average for over-ear headphones — based on 150 of 240 we've cataloged.
Usb-c is the most common — on 87% of the 135 over-ear headphones we've cataloged (of 240).
5.2 appears on 18% of the 145 over-ear headphones we've cataloged (of 240).
above average for over-ear headphones — based on 195 of 240 we've cataloged.
The Shure AONIC 50 (Gen 2) can connect to anything and are decent do-anything headphones. The sound needs a little tweaking, but since the app allows you to use parametric EQ filters, it's a gem.
Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
