Neat Bluetooth solution
Apologies for reviving this thread, but I wanted to share a good solution for BT handsfree.
https://www.aliexpress.com/item/New...ngle-5-10km-K-M-Plug-for-TYT/32891346512.html - but available from eBay etc etc etc
I bought this to use with a TYT MD380 DMR handheld, but it will work fine with Kenwoods that use the usual 2.5/3.5mm plugs. (Also most Baofengs FWIW).
You get a good quality BT earpiece, a dongle that plugs into the side of the transceiver, and a PTT button with a velcro strap so you can attach it to the handbrake, gear lever, steering wheel or whatever.
I've been using this setup pretty much every day for the last 3 months and it's worked very well. I get unsolicited comments about the good audio quality (and judging from the parrot, it does sound nice).
Caveats:
1. You'll need to charge the modules from time to time. The PTT rarely needs charging. I charge the earpiece and dongle maybe every 10 days or so. I keep them turned off in between use. That prolongs battery life, but means you need to pair them up each time - it's just a long press of a button and takes a couple of seconds.
2. The PTT has a slight lag of a couple of secs. That's no problem with DMR where there is a delay in any case. For FM it might be a nuisance if you want to break into QSOs between overs.
3. There is a cheaper version with a different earpiece - I can't comment on the audio quality of that. There is also a version with no PTT button. Take care when buying.
