With the virus outbreak, many people start to care more about their hygiene. Wearing masks and washing hands become the basic process when you go out. However, considering the current situation, you also need to care much more about your earphones’ hygiene even when you are listening to music. UV sterilization earphones are quite necessary. Supported by Qualcomm, Tronsmart launches its first UV sterilization TWS earphones called Onyx Free. What shall we expect from these anti-virus earphones?


UV Sterilization - Safer Than Ever

Equipped with UV sterilization, Tronsmart Onyx Free provides you with a cleaner and safer use. Simply put the earbuds in the charging case and the UV will automatically sterilize the bacteria for 30 seconds. It allows you to have a safer experience than ever.


Genuine Qualcomm® Chips

Engineered with Qualcomm® chips, you’re allowed to obtain a more stable connection and much better sound quality with the faster transmission, ultra-low latency and low-power consumption.


Panasonic Tactile Switches

Equipped with Panasonic tactile switches, Tronsmart Onyx Free provides you with more precise and more comfortable control with 71% ear pressure off compared with the ordinary button control earphones.


IPX7 Rated for Enhanced Performance

Tronsmart Onyx Free is designed with IPX7 waterproof feature. It means you can enjoy your music whether it rains or sweats, and you can even rinse the earbuds under the water.


Studio Sound Quality

With real Qualcomm® chip, Tronsmart Onyx Free supports aptX™ lossless audio format. It can give you a very dynamic and vivid sound experience.


Long Battery Life

Provide up to 7 hours of playtime on a single charge while 35 hours with the charging case.


Go Mono or Stereo

Onyx Free allows you to use **one or two earbuds with mono or stereo mode. The voice assistant gives you a hands-free operation experience.

(**The earbuds can support mono and stereo mode, which means you can use two different bluetooth devices to connect to your these two earbuds separately, but you need to make sure that the two earbuds are not close to each other, 20-30m apart at least. Otherwise, the earbud will automatically choose to connect to the other earbud instead of the other bluetooth device.)

Above all, Tronsmart Onyx Free is one of the best choices for you not only because of the UV sterilization for anti-virus but also because of its high performance and all the great features it offers in this price range.
