Bose was ahead of the curve with these headphones, but there are newer options nowadays.
A 4.5 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.
below average for over-ear headphones — based on 150 of 240 we've cataloged.
Micro usb appears on 10% of the 135 over-ear headphones we've cataloged (of 240).
4.1 appears on 3% 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 Bose QuietComfort 35 II have some of the best noise canceling in the business, and they're regarded as one of the most comfortable headsets around. With a great default frequency response, travel-friendly design, and solid mic system, there's plenty to love about the QC 35 II.
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.
