UMIDIGI True Wireless Earphones Black

These UMIDIGI earphones use Bluetooth 5.0 for a stable link up to 10 metres. Each bud holds a 50mAh cell while the case stores 300mAh, delivering about 4 hours of play time. A full recharge takes roughly 60 minutes via DC 5V input. The 16 ohm drivers cover a 20-20000Hz range.

Suits daily commuters and office calls

Lightweight design and ergonomic fit make them comfortable for long wear. Broad compatibility with iOS and Android phones covers most users. Buyers needing active noise cancellation or longer continuous playback should consider other options. Not built for professional monitoring or high-intensity sports.

Battery life around 4 hours per charge

The 50mAh earbud batteries set the practical limit for a single listening session. The 300mAh case adds several top-ups before it needs a wall socket. Check your typical session length against this figure before buying.

Questions about this item

Do I need a phone with Bluetooth 5.0 to use these earphones?

The earphones use Bluetooth 5.0 and are widely compatible with iOS and Android mobile phones, so they will pair with devices that support earlier Bluetooth versions as well.

Can I keep using my existing USB charger with the charging case?

The charging case accepts a DC 5V power input, which matches the output of standard USB chargers, so your current charger can be used.

How do I confirm the earphones are delivering sound correctly after pairing?

Play audio and verify you hear the full frequency range of 20 to 20000 Hz at the 16 ohm impedance; the earphones should provide about 4 hours of use on a full charge.
