Pros & Cons
- Balanced, detailed sound — unusually good for the price
- Up to 50 hours of battery with ANC on
- LDAC support for high-bitrate Android listening
- Lightweight and comfortable
- Multipoint connectivity
- Noise cancelling is only average
- Doesn't fold — ear cups only swivel flat
- Older Bluetooth 5.0
- Plain, plasticky design
Design and Comfort
The SonoFlow keeps things simple: a lightweight 250 g frame, soft protein-leather pads and a gentle clamp. Owner reviews frequently mention comfort for long listening sessions. The ear cups swivel flat to fit the included case, but there's no folding hinge, so it's bulkier in a bag than some rivals. The design is plain and mostly plastic, but solid.
Sound Quality
This is where the SonoFlow shines. Instead of the heavy bass boost common at this price, its default tuning stays close to a reference target, with a moderate bass lift that adds warmth without bleeding into the mids. Published measurements and owner reports both point to clear vocals and good detail, helped by diamond-like carbon drivers. Android listeners can use LDAC for higher-bitrate streaming.
Noise Cancellation
Noise cancelling is the SonoFlow's weak spot. It takes the edge off steady background noise like air conditioning and engine hum, but it's clearly behind the best budget ANC headphones. Think of it as a great-sounding headphone with some ANC, rather than an ANC headphone first.
Battery and Connectivity
Battery life is superb: up to 50 hours with noise cancelling and around 70 without. Multipoint is supported, and while Bluetooth 5.0 is older, owners report stable connections.
Who Should Buy the SonoFlow
- Music-first buyers on a budget who care most about sound quality.
- People who hate charging — the battery lasts for weeks of normal use.
- Android users who want LDAC under $100.
If noise cancelling matters most, the Anker Soundcore Space Q45 is the better pick.
Final Verdict
The 1More SonoFlow is a budget headphone made for listening. Balanced sound, LDAC and a giant battery make it a fantastic value — just don't expect class-leading noise cancelling.
