ANYSECU HB880 Hands-Free Bluetooth PTT Headset - Motorcycle Helmet Communication System Compatible with Baofeng UV-5R, TH-UV8000D, UV-82, UV-5RE Two Way Radios - Perfect for Riding, Construction, Security & Outdoor Adventures

Oh brother. I was excited to see a bluetooth solution with PTT for radio use on the market, and I immediately bought one of these. Yikes. Glad Amazon let me return it.I first noticed that the components were made of toy plastic and not very well molded; I don't believe the control box would provide any resistance to rain if tested but I was not brave enough to test this. The left earphone did not work unless the 3.5mm jack was held in with considerable force, and would then give partial audio. However, I thought I'd give it the benefit of the doubt and see how it fared, and connected everything up to a radio.The volume for some reason defaults to "very low" every time the unit is powered on and requires between 5 and 30 clicks of the volume button to reach max volume (it was different every time I tried it and provided no change until reaching max); meanwhile the audio is so quiet at max volume it can barely be heard over engine noise when stationary; the radio was completely inaudible when riding at 30 MPH in a full face helmet. The volume down button immediately got stuck in the poorly molded frame while I was trying to troubleshoot this, preventing me from shutting the unit off until I pried the button back up with a small knife. I also instantly became aware that the foam windshield for the mic just falls off. Every time. Don't even think about trying to use it unless you rubber-band that bastard on.FYI, while this will also pair with bluetooth-capable Motorola radios directly (so it DOES use HSP bluetooth, yay), the PTT buttons ONLY work with the included baofeng two-prong radio adapter. I paired the unit with my cell phone as well, and this pairing took immediate primacy. I was unable to pair the device with a radio until I removed it from my phone entirely and put the unit in pairing mode to clear that history. More bizarrely, each time I turned the unit on it forgot its pairing information (unless it was my cell phone), so each time I switched the unit on I had to put it in pairing mode, re-pair it, and click the volume up button for a while to get usable audio... and then squeeze the 3.5mm jack in so it would sort of work in both ears every time I received something.All in all, the best made part of this was the metal clip to hold it to a helmet. The whole unit has an actual value of maybe $9.25 and is being sold for $75. Returned, do not recommend.
