OK.
Up until very recently I was using the UHF as designed. I tried using earphones plugged into the back of the radio, but the wires kept breaking. To use the microphone, I had to:
- set the cruise control,
- flip the helmet up with the left hand,
- then grab the left handle bar,
- then grab the mic with the right hand,
- speak,
- hang the mic back up,
- Flip the helmet back down,
- grab the right handle bar.
So replying to a conversation can only be done at opportune moments which makes for disjointed conversations.
Recently I bought a Sena SR10 from the USA (ebay motorcycle-works) for US$ 144 delivered. In the pack is the SR10, the PTT button, an extension cable for the PTT button, an audio lead, a USB charging cable, a 12V accessory socket charging cable, and a handlebar mounting attachment.
My helmet bluetooth is an Aldi one.
I find this a much better and safer way to use the UHF. I don't recommend trying the other way without cruise control.
Because the SR10 is a mono device, my phone won't connect the media played to the SR10 without an audio cable. But that is easily fixed.
