Nothing Headphone (1) Pro features unnecessary driver complexity and poor acoustic consistency

The Nothing Headphone (1) Pro suffers from excessive driver complexity and significant acoustic inconsistency, undermining its performance despite the inclusion of parametric EQ. The device utilizes a triple-driver design—two dynamic drivers and one xMEMS driver—which the reviewer argues is unnecessary and detrimental to the overall sound quality. Measurements conducted on B&K 5128 and in-ear rigs reveal a harsh, compressed sound signature, particularly in the low-to-mid treble region around 5 kHz, which negatively impacts percussive sounds like snare drums and cymbals. While the headphone offers parametric EQ, the reviewer notes that the in-situ behavior is highly variable across different users, making it difficult to achieve a consistent, balanced sound. The product's design appears to prioritize marketing novelty over acoustic performance, failing to match the consistency and sound quality of competitors like the Bose QC Ultra (Gen 2) or the Sennheiser HDB 630. Although the noise cancellation and transparency modes are acceptable, the fundamental acoustic design flaws and channel imbalances make it difficult to recommend.

The Nothing Headphone (1) Pro uses an unnecessary triple-driver design that complicates the acoustic output. A harsh 5 kHz peak in the frequency response causes percussive sounds to feel compressed and unpleasant.

The headphone exhibits significant channel imbalance, which cannot be fully corrected by the included parametric EQ. In-situ frequency response measurements show high variability, indicating that the sound will differ significantly between users.

The device's acoustic performance is inferior to competitors like the Bose QC Ultra (Gen 2) and Sennheiser HDB 630. The inclusion of parametric EQ is a positive feature, but it is insufficient to overcome the headphone's fundamental design flaws.
