Product Overview

How to wear

Select & replace eartips

To get the optimal experience, we recommend that you give each of the different-sized ear tips a try and find the pair that fits your ears the best. The medium-sized ear tips are pre-mounted onto the earphones. Please ensure that the ear tips are firmly attached.

Flip the ear tips over and mount them onto the earphones. Then adjust the whole to aim at the microphone hole.

Fitting adjustment

Insert the earphone into your ear and adjust it to a position that you’re comfortable with. The better the fit, the better the noise isolation will be.

How to charge

With up to 8 hours of battery in the earphones and 3-3.5 charges in the charging case, Avantree TWS120 offers up to 36 hours of playtime.
