For anyone being somewhat phobic regarding bacteria, Audio Technica has come up with the ATH-TWX9.
Keeping your in-ears clean is actually a bitter necessity. After frequent use, those things just get a little dirty. At least the Audio Technica ATH-TWX9 in-ears do away with bacteria. And that, in turn, is thanks to the included charging case. Not only does it contain a rechargeable battery, so you can listen for long periods without plugging in on the go, but also a sterilization system based on UV light. A thorough 70-second sterilization is performed per charge. Of course, you still need to remove any non-bacterial “fouling” on the caps on a regular basis yourself.
Otherwise, the Audio Technica ATH-TWX9 is a modern set of in-ears, with support for Bluetooth 5.2. ANC is also available, as well as a low latency mode for during gaming. Hands-free calling is no problem. Available in the color “Japanese Black” with bronze accents, at a cost of €319.
