Air Conduction Open-Ear Bluetooth 5.3 Earphones

Enjoy all-day listening comfort, low-latency audio, and clear sound performance with the Liu Yin Ow-520 Air Conduction Open-Ear Bluetooth 5.3 Earphones. Featuring a modern clip-on ear-hook architecture, these non-in-ear earphones use directional air conduction to transmit high-fidelity bilateral stereo sound straight into your ear canal without blocking it—allowing you to stay fully aware of your surroundings while commuting, working out, or managing calls.

Constructed from lightweight ABS plastic, the Ow-520 ear-clip design provides a firm, slip-free grip that eliminates ear canal pressure during extended wear. Powered by an advanced Bluetooth 5.3 Jerry chipset with low-latency e-sports performance, the charging case features an integrated LED digital display screen for instant battery tracking. Delivering 4 to 8 hours of continuous audio playback per charge, it offers hands-free calling, music control, and a sleek active-sports aesthetic.

Key features and technical specifications include:

* Non-In-Ear Air Conduction Technology: Directs rich stereo sound into the ear without occluding the ear canal, preventing ear fatigue and preserving situational awareness.

* Ergonomic Ear-Clip Hook Design: Lightweight C-bridge clip grips comfortably around the outer ear cartilage for a secure, bounce-free fit during active movement.
