SOVAWIN M12 TWS Bluetooth 5.0 Headset

The SOVAWIN M12 is a true wireless stereo headset built around a Bluetooth 5.0 chip for stable, low-latency audio. Its ergonomic, split-ear design fits securely on the auricle, making it suitable for sports and daily commuting. Each earpiece works independently, so you can use one earbud alone or both together. IPX7 water resistance protects against splashes and sweat during workouts.

Magnetic charging case with LED power display

The bundled charging compartment holds polymer lithium batteries that recharge the earbuds magnetically, delivering up to four hours of playback per charge. A built-in USB output rated at 5V 1A lets the case act as an emergency power bank for a smartphone. LED indicators show remaining case capacity at a glance, while touch controls on the earbuds handle playback, calls and voice-assistant access without reaching for your phone.

Bluetooth 5.0 range and audio limits

The headset maintains a reliable link up to ten metres in open space, but walls or interference will reduce that distance. Frequency response spans 100 Hz to 8 kHz with a signal-to-noise ratio of 70 dB, which is adequate for voice calls and casual listening but not for critical music monitoring. A2DP, AVRCP, HSP and HFP profiles ensure broad compatibility with iOS and Android devices, yet the codec set is limited to the mandatory SBC encoder.

Questions about this item

How long do the polymer lithium batteries last before they need replacing?

Each earbud delivers about 4 hours of playback on a full charge, and the charging case provides additional cycles via its 5 V 1 A USB output.

What limits continuous listening time on a single charge?

The built-in cells run for roughly 4 hours before the earbuds must return to the magnetic charging case for a top-up.

Do the earbuds get hot or noisy during all-day use with the case?

The IPX7-rated ABS shells stay cool and silent; only the case draws 5 V 1 A while recharging the buds between sessions.
