Open-Ear Comfort

The Yeforu JM13upgrade headphones sit outside the ear canal with soft silicone hooks that rest over the ear. They use air conduction so you hear audio while staying aware of surroundings. The open design avoids the pressure of in-ear buds and works comfortably with glasses.

Suited for all-day awareness

Ideal for runners, commuters and office workers who need to hear traffic, announcements or colleagues while listening. The secure hooks stay put during movement. Not for listeners who want passive noise blocking or deep bass isolation from sealed ear tips.

35-hour case capacity

The charging case stores enough power for up to 35 hours of total playback, while each earbud run delivers up to 7 hours. A full case recharge takes 1 hour. This figure decides whether the kit matches your daily usage between wall charges.

Questions about this item

Does the 32-ohm impedance draw enough power to drain a phone battery quickly during all-day use?

The earbuds run for up to 7 hours per charge and the case adds another 35 hours, so daily listening is well covered without stressing the phone.

What source device is needed since there is no jack on the earbuds?

Any Bluetooth audio device such as a phone, tablet or laptop will pair wirelessly; the earbuds have no wired connector.

Can the open-ear design stay stable alongside glasses frames during long sessions?

Soft silicone hooks sit over the ear without pressing on frames, so glasses wearers report a secure, comfortable fit for hours.
