1. Bluetooth is universal, and general mobile phones are compatible with incoming calls with Bluetooth.

2. If it is used to listen to songs and need mobile phone support, the general mobile phone does not support, only Nokia's mobile phone supports mono to listen to songs.

3. But if the phone has Bluetooth stereo function, you can purchase a Bluetooth stereo headset to listen to the song. Another thing to note is that if a Nokia phone without Bluetooth stereo is listening to music using a Bluetooth stereo headset, it only reflects the two-channel effect.
