1MORE SonoFlow Pro Wireless ANC Over-Ear Headphones

1MORE SonoFlow Pro HQ51 Wireless Active Noise Cancelling Headphones

The 1MORE SonoFlow Pro HQ51 wireless active noise cancelling headphones are built for listeners who want studio-grade sound without giving up everyday comfort. At the core is a 40mm diamond-like carbon dynamic driver paired with LDAC lossless Bluetooth transmission, delivering data speeds up to three times faster than standard SBC codecs for a noticeably cleaner, more detailed listening experience.

Beyond sound quality, the QuietMax dual hybrid noise cancellation system blocks out over 42dB of external noise, making these headphones a practical choice for commuting, working from busy offices, or simply focusing at home. With up to 100 hours of playback (ANC off) or 65 hours with ANC on, battery anxiety is no longer part of the daily routine.

Whether you're taking calls on a windy street or fine-tuning your music with 12 professional EQ modes tuned by a Grammy Award-winning engineer, the SonoFlow Pro HQ51 adapts to how you actually listen.

Key Features

• LDAC Lossless Bluetooth Audio: Transfers audio data up to 3x faster than SBC codecs (up to 990kbps), so you hear more of the original recording with less compression loss.

• Diamond-Like Carbon Diaphragm: A 40mm strong magnetic DLC driver combines diamond-level hardness with precise sound reproduction, giving you clean, balanced audio across genres.

• QuietMax Dual Hybrid ANC: Cancels over 42dB of ambient noise using a dedicated chip and custom acoustic design, ideal for noisy commutes or shared workspaces.

• 100-Hour Battery Life: Up to 100 hours with ANC off and 65 hours with ANC on, so long flights, workweeks, or travel days won't drain the battery before you do.

• Grammy-Tuned Sound Profile: Tuned by Grammy Award-winning engineer LUCA to compensate for frequency loss caused by noise cancellation, keeping sound natural and low-distortion.

• 12 Professional EQ Modes: Studio-crafted presets let you match the sound signature to your music or mood without needing a separate equalizer app.

• Intelligent Call Noise Reduction: AI-powered microphone algorithm filters ambient and wind noise automatically, keeping your voice clear on calls even outdoors.
