I use the interphone BT model like the one in this link

I bought it as wasn't sure if I'd use intercom sets so for the price compared to the Sena's these were a cheap investment. Turns out they're perfect for what I need. They're great for talking to my partner when she's on the back and I use them to take the occasional call. The most I use them for is listening to Spotify.
The controls are really simple and connectivity to devices is quick and easy. Generally they're great value for the price! But that's just my opinion! 😁
