A 4.2 puts its noise isolation / ANC in the bottom third of over-ear headphones we've measured.
Measured on 86 of the 240 we've cataloged.
above 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).
5.3 is the most common — on 26% of the 145 over-ear headphones we've cataloged (of 240).
Bluetooth is the most common — on 44% of the 215 over-ear headphones we've cataloged (of 240).
The Anker Soundcore Space Q45 is a great pair of active noise canceling (ANC) headphones, and the $150 USD price tag only sweetens the deal. While the sound profile doesn't quite match our platonic ideal, it's adequate for most listeners. Unlike many mid-tier wireless headphones, the Q45 microphone system rejects quite a bit of background noise, making this a great work headset too. If you're willing to put up with the mobile app and sound quality, you'll enjoy the Space Q45 from Anker's brand Soundcore.

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.
