# Active noise cancellation and microphones
# Battery life and charging trade-offs Pro carries a 1,060 mAh battery. Nothing advertises up to 30 hours of playback with ANC enabled and up to 68 hours with ANC disabled. The Pro supports fast charging: five minutes plugged in delivers up to four hours with ANC off or two hours with ANC on. This represents a shorter runtime in some conditions compared with the original Headphone 1's tested numbers, where SoundGuys recorded roughly 42 hours with ANC on and 80 hours with ANC off in their tests of the prior model.
# Software features and studio tuning Nothing collaborated with London's Metropolis Studios on tuning and software features. The headphones include a physical Flat EQ Switch on the left earcup to instantly select a neutral profile. There's also a Dynamic Spatial Audio mode with head tracking that offers five spatial profiles, plus support for Custom EQs. The device supports Bluetooth 6.1, Auracast broadcasting, dual-device pairing, Google Fast Pair, LDAC, and Hi-Res Audio over wired and wireless connections.
# Materials and comfort changes Nothing's distinctive transparent aesthetic but moves to more premium materials: an aluminum frame, titanium arms, and scratch-resistant 9H Panda Glass on the earcup windows that reveal internal elements. The headband is wider and thicker, while the ear cushions are softer, changes intended to improve comfort though Nothing's claims await independent testing.
# Price, availability, and positioning
# Practical takeaway for buyers If you prioritize richer detail in treble, clearer separation between frequency bands, stronger ANC, and a more premium build, the Headphone 1 Pro focuses on those areas. Expect shorter battery runtimes versus the original in some scenarios, but faster top-up charging. Compare ANC and battery in hands-on reviews if long runtimes or maximum noise suppression are your primary needs.
