1more SonoFlow SE HQ31 Blue Wireless On-ear headphones

Wireless Over-Ear Headphones with Hi-Res Sound and Hybrid ANC

The 1MORE SonoFlow SE HQ31 Blue delivers Hi-Res and Hi-Res Wireless certified audio through a custom 40mm titanium-coated composite driver, tuned by a Grammy-winning sound engineer for warm, balanced tones. Bluetooth 5.4 with the LDAC codec keeps high-resolution tracks detailed without a cable, and QuietMax hybrid active noise cancellation reduces ambient noise by over 42 dB. A Transparency mode lets listeners hold a quick conversation without removing the headphones.

What Sets the SonoFlow SE HQ31 Apart

At the core sits a 40mm titanium-coated composite dome diaphragm that produces rich, resonant sound with strong transient response. 1MORE's patented QuietMax hybrid ANC combines feedforward and feedback microphones with advanced algorithms to cut noise by over 42 dB, while 360-degree spatial audio widens the soundstage for movies and games. The companion 1MORE app adds 12 studio-calibrated EQ presets, a custom 10-band EQ, a low-latency gaming mode, and over-the-air firmware updates.
