The 1More SonoFlow Mini uses an over-ear fit and weighs 181 g, making it a relatively lightweight option in its category. It is designed specifically for kids and features a foldable build that simplifies storage and transport. The headphone has a closed-back design and includes stereo speakers, though it does not come with a travel bag.
The 1More SonoFlow Mini is equipped with a 40 mm driver unit and an impedance of 32 Ohms, with a sound pressure level of 90 dB/mW. It offers passive noise reduction to help block out ambient sound, though it does not include active noise cancellation or support spatial audio. The headphone also does not use a neodymium magnet in its driver construction.
The 1More SonoFlow Mini runs on a built-in rechargeable battery rated for 65 hours of playback, and it charges via USB Type-C for convenience. A battery level indicator lets users keep track of remaining charge at a glance. The battery is not removable, and the headphone supports neither wireless charging nor solar power.
The 1More SonoFlow Mini connects wirelessly via Bluetooth 5.4 with a maximum range of 10 m. It does not support any advanced audio codecs, including aptX, aptX HD, aptX Adaptive, aptX Lossless, aptX Low Latency, AAC, LDAC, or LDHC, nor does it include Bluetooth LE Audio or Auracast. Fast pairing and NFC-based pairing are also absent, so the headphone relies on standard Bluetooth pairing only.
The 1More SonoFlow Mini includes a single microphone and can function as a headset for calls, with controls accessible directly on the headphone via an on-device control panel. It supports multipoint connectivity for up to two devices simultaneously, allowing it to stay paired with more than one source at a time. There is no in-line control panel, no ambient sound mode, no in/on-ear detection for auto-pausing, and no dedicated mute function.
