The Nothing CMF Headphone Pro (B175) combines powerful sound, intelligent noise cancellation, and signature minimalist design inspired by Nothing’s distinctive transparent aesthetic. Equipped with custom 40 mm dynamic drivers and Nickel-plated PEN+PU diaphragms, these headphones deliver rich, detailed audio across the full 20 Hz–20 kHz spectrum. Tuned by Nothing for natural accuracy and balance, the Headphone Pro features Hi-Res certification in both wired and wireless modes, ensuring consistent quality with AAC, SBC, and LDAC codecs.
With Hybrid Active Noise Cancellation of up to 40 dB and environment adaptive algorithms, distractions fade while your music remains pure. A transparency mode allows ambient sound in for situational awareness.

A quick 5-minute charge provides up to 8 hours of listening (ANC off). Designed for comfort, plush memory-foam cushions, a lightweight 283 g frame, and an adjustable fit make them ideal for all-day wear. With Bluetooth 5.4 dual-device connectivity, Nothing X app integration, and dynamic control sliders for tone customization, the CMF Headphone Pro offers a blend of innovation, precision, and convenience engineered for modern listeners.
