FAQs
1. How do I switch between Bluetooth and TF Card mode? When a TF card is inserted, the earphone usually defaults to card playback. To switch, you can remove the card or use the multi-function button (usually a double or triple click depending on the firmware) to toggle modes.
2. Is it safe for heavy rain or swimming? No. It has an IPX4 rating, which protects against sweat and light splashes (like light rain). It should not be submerged in water or worn in a shower.
3. Does it show the battery on my phone? Yes, most Android and iOS devices will display a small battery icon in the status bar, but the LED display on the neckband itself provides a more accurate 1–100% reading.
4. How do I control the music tracks? * Next Track: Long-press the “Volume +” button for 2 seconds.
-
Previous Track: Long-press the “Volume -” button for 2 seconds.
-
Play/Pause: Single press the multi-function button.
5. Why does it take 3 hours to charge? Because the battery is 800mAh (roughly 4–5 times larger than standard neckbands), it requires a longer full-charge time. However, the fast-charging feature ensures you can get a full day’s worth of music in just 10 minutes.
