Comfort for small ears and glasses

These clip-on headphones use an open-ear design that rests outside the ear canal. The C-shaped bridge and 4.3g per bud weight aim to eliminate pressure during long sessions. Bluetooth 5.4 provides a stable link up to 10 metres. The charging case delivers up to 40 hours of total playtime.

Suits outdoor awareness, not isolation

Runners and commuters who need to hear traffic will benefit from air conduction technology. Passive noise cancellation only reduces ambient sound slightly. Buyers who want active noise cancellation or deep bass immersion should look at something else. The on-ear fit may not suit users preferring in-ear seals.

40-hour case battery with digital readout

The case stores enough power for 40 hours of listening and shows the exact percentage on a built-in display. A low-battery alert beeps before shutdown. This single figure determines whether the endurance matches your weekly routine.

Questions about this item

Do these clip-on earbuds need anything besides a phone with Bluetooth 5.4 to start playing audio?

No, they pair directly to any device that supports Bluetooth 5.4; the charging case only stores power and shows the remaining battery level.

Will the open-ear design still let me hear my wired headset’s microphone if I keep it plugged into the same PC?

Yes, the earbuds sit outside the ear canal so ambient sound — including a wired headset’s mic monitoring — passes through naturally while Bluetooth 5.4 handles the wireless link.

How can I confirm the 40-hour playtime is actually being delivered after the first charge?

The case’s digital display shows the remaining battery percentage; as it counts down during use you can track real-world runtime against the rated 40 hours.
