True wireless earphones for daily listening

Thermals noise and power draw

The low-power Bluetooth 5.0 link and 16 ohm impedance keep energy draw modest during music or calls. With no active cooling parts the earpieces stay silent and generate no noticeable heat in normal use.

Questions about this item

How do I pair the UMIDIGI S11 earbuds via Bluetooth 5.0, and what step do people often miss?

Open the charging case, remove both earbuds, and select "S11" in your device's Bluetooth menu; the step many miss is taking both buds out together so they enter pairing mode simultaneously.

Which battery will need replacement first on the S11, and what are its rated capacities?

Each earbud uses a 50 mAh cell while the case holds 300 mAh; the smaller earbud batteries cycle more often and will degrade before the case.

What limits continuous playback on the S11 during a long session?

The earbuds provide about 4 hours of use per charge, so the 50 mAh battery capacity is the first limit reached under sustained listening.
