Open-ear comfort for daily use

The allentian K23 hanging-ear headset uses an open binaural design that avoids pressure on the ear canal, making long sessions more comfortable. Bluetooth 5.3 provides high-speed, stable audio and video transmission. Pulse TD3.0 adaptive directional sound transmission detects ear-canal shape and adjusts the beam angle for efficient delivery, reducing sound leakage by 89 per cent.

Suited to listeners who want awareness

These earphones suit users who prefer to stay aware of their surroundings while enjoying music or calls. HIFI sound quality with digital enhancement restores natural scene audio. Intelligent CVC8.0 noise reduction improves call clarity in noisy environments. Buyers who need active noise cancellation or sealed in-ear isolation should consider other form factors.

Simple touch control and USB-C charging

Touch adjustment on the earbuds handles playback and calls without reaching for a phone. Each earphone weighs 11.5 grams and the complete system weighs 93 grams. The case charges via TYPE-C and holds a 450 mAh battery alongside the 100 mAh earbud cells, delivering about 14 hours of music playback at medium volume.

Questions about this item

What device must support Bluetooth 5.3 for these earphones to pair and stream audio?

Any smartphone, tablet or computer with Bluetooth 5.3 will connect to the K23 earphones and deliver the high-speed, stable transmission they are designed for.

Will the open-air design let someone nearby hear my music if I keep my old in-ear tips for comparison?

Pulse TD3.0 adaptive directional sound transmission cuts sound leakage by 89 %, so even at moderate volume the audio stays directed into your ear canal rather than escaping outward.

How can I confirm the earphones are transmitting sound efficiently after the first fit?

The adaptive beam automatically adjusts to your ear-canal shape; if music sounds clear and calls come through without environmental noise thanks to CVC 8.0, the directional transmission is working as intended.
