What the Air 31 TWS delivers

The Midcomsys Air 31 TWS are true wireless earbuds built for music listeners and gamers who want a compact, cable-free setup. They come with a charging case and a Type-C cable in black. The product is new and ready to pair with phones, tablets, laptops and other Bluetooth devices.

The spec that decides fit

Bluetooth 5.3 is the single connection standard these earbuds use, so your source device must support that version or fall back to an earlier one. If you need a wired option, a different audio codec, or a specific gaming console protocol, this model will not meet that requirement.

Install experience and common issues

Pairing starts when you open the case and select the earbuds in your device's Bluetooth menu, a process that usually takes a few seconds. Touch controls handle playback and calls, but accidental taps can trigger commands while you adjust the fit. The Type-C case recharges the buds for up to 24 hours total listening time.

Questions about this item

What does 24 hours of battery life mean for daily use?

The charging case holds enough power for 24 hours total playback, so you can recharge the earbuds several times before plugging the case in again.

What does Bluetooth 5.3 actually limit in real use?

Bluetooth 5.3 sets the maximum wireless protocol version; range, stability and codec support will still depend on the phone or laptop you pair with.

What do I need to charge the case?

A USB Type-C cable is included; plug it into any standard USB power source such as a laptop port or phone charger.
