Bluetooth 5.3 for Strong Connection and Long Range: With Bluetooth 5.3, these earbuds support HSP/HFP/A2DP/AVRCP and provide fast and strong connection and transmission. This means you can enjoy low latency listening. Plus, they pair easily - just take them out of the case and they'll connect to your device and each other.

Great Sound Quality and Clear Calls: The FEANS A6 Earbuds have 10mm speaker drivers, which are twice as big as usual. This gives you a wide sound range, from powerful bass to clear treble (20Hz-20KHz). You can use them in mono or stereo mode, and each earbud has a built-in mic for clear calls.

Long Battery Life and LED Display: The charging case has a digital display that shows the battery level. When it's charging, the display will flash the number. The earbuds will charge when you put them in the case, and the display will show the battery level for each earbud until they're fully charged. The 400mAh case can charge the earbuds six times, giving you 60 hours of playback time in total. Each earbud lasts five hours on a single charge.

Comfortable Design: The A6 earbuds are designed to fit your ears perfectly, thanks to research on thousands of people's ear canals. They come with three sizes of ear tips to ensure a comfortable fit for everyone, whether you're running, jumping, or just relaxing. The soft silicone ear tips are gentle on your ears and won't put too much pressure on them.

Easy to Use and Waterproof: You can control your music and calls easily with the smart touch sensor. The earbuds are also waterproof, thanks to nanotechnology that keeps them safe from sweat and rain. This makes them perfect for sports and exercising. You can enjoy your music while jogging, in the shower, or just running errands.
