The best-seller Arbily/HolyHigh TWS-X9 now has its little friend: TWS-X9 Mini pushed the portability to extreme. Its size is no larger than a car key, which means it can fit any pocket. The single ear design and specially tuned noise cancelling level make it the perfect choice for daily commuting, driving and travelling.


Note: The earbud comes with Left and Right ear versions. Please confirm before placing order.




The Smallest True Wireless Earbud in the World

TWS-X9 Mini packed all the must-haves of a wireless earbud in its tiny body and charging box: 40mAh earbud battery and 300mAh for the charging case, Bluetooth 5.0, basic waterproof, microphone and universal micro-USB charging port.


3X Speed/Range Transmission

The latest Bluetooth 5.0 technology carries stronger signal transmission capability than Bluetooth 4.2, 3 times to be specific. The wireless earbud not only delivers stable, clear sound with no interruption, it provides high fidelity audio at lower power consumption.


One Charge for One Week

The built-in battery provides 3 hours playback time with a single charge, and the key-sized charging box can charge earbud to full for 6 times. Each charge takes 1 hour. It’s not fast charging but remember, you can always put the charging box in your pocket and let it juice the earphone silently and safely.


Ergonomic Design for Teleconference

The exterior design of TWS-X9 Mini inherited the well-accepted TWS-X9, which was shaped from hundreds of real persons’ ear mold. Tested by Arbily Lab for 1000+ times, TWS-X9 Mini ensures comfortable wearing even after long time of teleconference or travelling.
