#122 Bose QuietComfort 45 Wireless Discontinued eBay
Pros: Excellent noise cancelling and a comfortable, light 240 g build. The measured tuning scores 76 on the Harman scale with a 2.29 dB spread, with clean bass about 2 dB above target that extends to 20 Hz and mids close to neutral.
Cons: Discontinued. A 9.1 dB dip near 8.7 kHz and an upper treble lift make cymbals sound uneven, and the original release had no EQ beyond a later bass and treble slider. There is no high resolution codec beyond AAC.
