Usage tips

The clip-on design is made to rest along the ear’s edge rather than sit inside the ear canal. The listed maximum size is 2.5 cm, so consider how that fit relates to your ear shape when choosing this style. For outdoor use, keep audio at a level that lets you remain attentive to your surroundings, particularly while cycling or walking near traffic.

Pair the earbuds with a Bluetooth-enabled device for listening and calls. Game Mode is available when low audio delay is useful, for everyday music, podcasts, or calls, the standard connection covers the main use cases. After workouts or exposure to rain, wipe the earbuds clean and dry them before charging.

Tips for day-to-day use

A deliberate touch and careful placement can help avoid unintended input. The included USB-C charging cable supports recharging, and the earbuds can also be used for online meetings, commuting, travel, and fitness.

Buyer feedback often praises the secure fit during activity. Sound, battery life, and Bluetooth connection receive mixed comments, so individual experiences vary. Some buyers also mention accidental touch activation. These are useful points to weigh alongside the open fit, call-focused ENC, and stated playtime when choosing earbuds for daily routines.
