A 7 puts its noise isolation / ANC in the top 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).
5.4 appears on 11% 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 CMF Headphone Pro offers solid battery life, ANC, and LDAC support for $99, with decent sound quality for casual listeners. However, the Energy Slider is more of a gimmick than a useful EQ tool.
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.
