MAGNETIC MICROPHONE
The world’s first open-ear earbuds with a detachable magnetic microphone.
Smooth left-to-right switching and one-touch attachment let you connect or remove the mic effortlessly, even without looking.

Exclusive innovation:
The OpenRock Link 20 uses N54-grade magnets protected by MagShield™ FusionTech with a six-layer noble metal coating.
This ensures sweat and corrosion resistance while maintaining signal integrity and reliable connection.
Tested for over 10,000 attach/detach cycles with zero performance loss.


5-MIC ARRAY WITH AI ENC
The 5-microphone array powered by AI Environmental Noise Cancellation achieves 99.9% noise suppression and reduces ambient sound by up to 58 dB, ensuring outstanding clarity even in challenging environments.


MICRO SIZE, MACRO SOUND
Despite being smaller than a quarter of a traditional headset, the Link 20 integrates a 30 mW speaker driver that delivers full, clear audio comparable to professional headsets.


ULTRALIGHT COMFORT – 9 g & 6.9° ERGONOMIC ANGLE
Weighing just 9 g per earbud, the ergonomic 6.9° tilt ensures zero discomfort during long use – ideal for extended shifts.
Soft silicone ear tips protect ear canals and maintain a secure fit for up to 12 hours of continuous wear.


FLEXIBLE AND STABLE FIT
0.8 mm titanium wire ear hooks with a 3.57 mm spacing offer adaptive flexibility and stability for all ear shapes.
Users can freely choose to wear the microphone on the left or right ear for maximum comfort and security.


DURABILITY & CONNECTIVITY
Bluetooth 6.0 provides ultra-stable connectivity – up to 15 m indoors and 30 m outdoors – and supports dual-device pairing for seamless transitions between office work, workouts, and outdoor use.
The earbuds feature IPX7 water resistance, while the magnetic microphone is IP55 dust- and water-resistant.
