CMF Headphone Pro B175 overview
The CMF Headphone Pro B175 is a new over-ear wireless headset from CMF by Nothing. It connects via Bluetooth 5.4 and includes a 3.5 mm cable for wired listening. The 40 mm dynamic drivers support Hi-Res LDAC audio. Adaptive active noise cancellation reduces external sound by up to 40 dB. A transparency mode lets ambient sound in when needed.
Who these suit and who they don't
Commuters and office workers who want long ANC battery life and adjustable bass or treble will like the 50-hour ANC playtime and the physical slider. The Nothing X app adds custom EQ and spatial audio profiles. Buyers who need more than 40 dB of noise reduction or who prefer a lighter frame than 283 grams should look at other models.
Installing and common issues
Pairing is quick with Google Fast Pair on Android and Microsoft Swift Pair on Windows. The headphones also work with iOS, macOS and other Bluetooth sources. The ear cups fold flat for storage. Some users report occasional multipoint connection drops when switching between two active devices. Firmware updates through the app usually resolve this.
