If you want longer battery life and noise-reduced calls for video calls, choose 1MORE Noise-canceling Headphones; if you need a lighter, more clearly specified everyday set with active noise cancellation, choose 1MORE SonoFlow Active Noise. For most people deciding between 1MORE HQ51 vs HQ31, I’d give the HQ31 the edge for its 90-hour playback claim and dual-microphone call processing, while the SonoFlow is the more straightforward pick if its lower listed weight and 70-hour battery fit your priorities. Neither spec sheet establishes wireless call latency, so I wouldn’t call either a proven low-latency headset for video calls.
If you want longer battery life and noise-reduced calls for video calls, choose 1MORE Noise-canceling Headphones; if you need a lighter, more clearly specified everyday set with active noise cancellation, choose 1MORE SonoFlow Active Noise. For most people comparing 1MORE HQ51 vs HQ31, I’d give the HQ31 the edge for its longer stated playback time and dual-microphone call processing. The SonoFlow is a reasonable alternative if its lower listed weight and simpler feature set suit you better. Neither product sheet specifies wireless call latency.
• SonoFlow’s biggest strength: a listed weight of 250 g, 70 hours of playback with ANC off, LDAC support, and 12 EQ presets in the app. Its trade-off: less stated battery life than the HQ31, and its call description gives fewer microphone details.
• HQ31’s biggest strength: up to 90 hours of playback and two microphones with AI-driven noise reduction for calls. Its trade-off: its listed weight is 0.43 kg, and its frequency range is specified as 20 Hz–20 kHz rather than up to 40 kHz.
• SonoFlow is for: someone who wants over-ear ANC headphones with a listed 40 mm DLC driver, app-based EQ choices, and a clear weight specification.
• HQ31 is for: someone who puts extra emphasis on long playback, transparency mode, spatial audio, and described call-noise processing.
• The two share some important basics: both are over-ear Bluetooth headphones, support LDAC, include active noise cancellation, offer transparency mode in their descriptions, and have a 3.5 mm jack. The differences are more useful than the shared checklist. Battery claims, driver descriptions, and call features point to different priorities.

The SonoFlow is the more straightforward option if you want over-ear headphones with a 40 mm DLC dynamic driver, LDAC support, and 12 EQ presets available through the 1MORE MUSIC app. Its listed frequency range reaches 40 kHz, and the product information identifies the headphones as 250 g. That combination makes it appealing to someone who wants to tune sound through presets without choosing a more feature-dense model.
For everyday listening, the product description also specifies QuietMax noise cancellation and both noise-cancellation and transparency modes. The advertised battery figure is up to 70 hours with ANC off. That’s a substantial stated runtime, but note the condition: the figure applies with ANC switched off, so it should not be treated as an ANC-on estimate.
For calls, the SonoFlow description mentions AI algorithms and beamforming microphones, but it doesn’t give a microphone count or a specific noise-reduction figure. I’d consider it for routine work calls if its overall feature set appeals to you, but I wouldn’t choose it solely because you’re searching for the best over ear headphones for video calls. The provided specifications don’t establish call latency or give a direct comparison of voice performance against the HQ31.
The HQ31 is the stronger fit on paper if long stretches between charges matter most. Its listed playback time is up to 90 hours, and the product description adds that a five-minute charge provides five hours of listening. As with the SonoFlow’s battery figure, treat these as manufacturer-provided playback claims rather than a guarantee for every listening setup.
Its call feature is more specifically described: two microphones work with AI-driven DNN noise reduction to help capture speech in noisy surroundings. That makes the HQ31 the more compelling spec-based choice for someone who takes calls from a shared office, café, or outdoor setting. It also includes a transparency mode, useful when you want to hear some of your surroundings without taking the headphones off.
The trade-offs are worth noticing. The HQ31’s listed weight is 0.43 kg, compared with 250 g for the SonoFlow, and its stated frequency range ends at 20 kHz. It has a 40 mm titanium-coated composite driver, LDAC support, and spatial audio, but those features do not by themselves prove better call quality or lower wireless delay. If your search is specifically for low latency earbuds for video calls, neither choice is an earbud, and neither product sheet provides a latency figure.
• Best for longer stated playback → 1MORE Noise-canceling Headphones. Its listed figure is up to 90 hours; the SonoFlow lists up to 70 hours with ANC off.
• Best for a lower listed weight → 1MORE SonoFlow Active Noise. It is listed at 250 g, while the HQ31 is listed at 0.43 kg.
• Best for more specific call-microphone details → 1MORE Noise-canceling Headphones. Its description names two microphones and AI-driven DNN noise reduction. The SonoFlow description mentions AI and beamforming microphones without giving a count.
• Best for app EQ presets → 1MORE SonoFlow Active Noise. Its sheet specifies 12 presets in the 1MORE MUSIC app.
• Best for spatial audio as a listed feature → 1MORE Noise-canceling Headphones. Its description calls out 360-degree spatial audio for activities such as movies and gaming.
• Best for a stated frequency range reaching 40 kHz → 1MORE SonoFlow Active Noise. The HQ31’s listed range is 20 Hz–20 kHz. This specification alone does not settle which one sounds better.
• Best for a quick-charge claim with a stated listening figure → 1MORE Noise-canceling Headphones. Its sheet says five minutes of charging provides five hours of listening; the SonoFlow sheet lists a five-minute charge time but does not say how much playback that provides.
• Best for a buyer prioritizing low-latency video calls → neither is a clear winner from the listed specifications. Neither sheet gives a wireless latency figure, so I would not assume either is the best low latency wireless headset for video calls.
In my opinion, I’d choose the HQ31 for video calls if I were deciding mainly from these specifications. Its two-microphone call system with AI-driven noise reduction is described more specifically, and its stated battery life is longer. I’d choose the SonoFlow instead if the 250 g listed weight and its 12 app EQ presets mattered more to me. For either model, I would verify compatibility and call behavior with my own devices rather than infer latency from Bluetooth support alone.
The HQ31 has the more detailed call specification: two microphones with AI-driven DNN noise reduction. The SonoFlow description mentions AI and beamforming microphones, but does not state a microphone count or latency figure.
The HQ31 lists up to 90 hours of playback, while the SonoFlow lists up to 70 hours with ANC off. These are different claims, and the supplied details do not give a directly matched ANC-on comparison.
Both are described as having active noise cancellation. The HQ31 description specifies QuietMax hybrid noise cancellation and says it reduces ambient noise by over 42 dB; the SonoFlow description identifies QuietMax but does not provide a comparable reduction figure.
I can’t determine value without current product pricing, and these specifications alone don’t establish it. Check the current price on Amazon, then weigh the HQ31’s longer stated battery life and more detailed call-microphone description against the SonoFlow’s lower listed weight and app EQ presets.
