So I bought the Scala headset a few months ago for a big ride. It is amazing. When I'm alone, the Bluetooth functionality allows me to listen to songs from my Blackberry all day long and even allows me to answer incoming calls hands-free. The sound is very good and battery life is exceptional. I do have an issue however. When paired with an earlier model that my cousin uses, we could talk all day long, but it never switches back to music when we stop talking. As I understand it, after 30 seconds or so of not talking, it should go back to playing music or whatever secondary function I choose. Likewise, if I took a phone call, it never swaps back to intercom after the call is ended. It seems like the VOX function is too sensitive and wind noise is causing it to stay in transmit mode all day long. This worked fine as long as we wanted to talk, but sometimes we'd run out of things to talk about and I just wanted to listen to some tunes. Instead, all I could hear is the sound of the wind in his helmet. We both are using full face helmets and riding bikes with windshields so the noise should certainly be below the threshold for VOX. Anyone with similar experience? I imagine there's an adjustment somewhere.
