Music while riding - Legal or Not

[Mattsplat]

Mattsplat, how do you rate them? Do you use them for music or just phone? They just seem quite cheep thats all.
Cheers

Been using this setup for over 2 years now.
Listen to music and get my GPS instructions from it all day long and Ive never flattened the battery.
I turned my mates onto this deal and they are also using these bluetooth intercoms without any problems.
Compared to 'branded' intercoms these are a steal
