Why is the Bluetooth signal so weak and often disconnects when I wear these headphones while swimming?
Because water underwater affects Bluetooth signal transmission, resulting in a weak signal. When using them underwater, please switch to MP3 mode.
Do these swimming earbuds have a shuffle mode for music?
These swimming headphones have a shuffle feature. In MP3 mode, the default setting is sequential playback; press the MFB
button three times to switch to shuffle mode.
How can I download my favorite songs to the headphones?
1)save the downloaded songs to your computer.
2)Use a USB data cable to connect the computer and the earphones.
3)Copy the songs directly from the computer to the earphone's internal storage
