My H500 headset works or not?

SOURCE: Can't connecto to headset again...

You are not alone in this endeavor. A lot of people have this problem. So, here is what I suggest. 1. Make sure both the headset and the phone are fully charged. 2. Delete the "device" from your phone. I mean precisely that. Go into you cell phone's bluetooth settings and erase your "HS850" from it. 3. Try re-pairing it. Put the phone and the headset in pairing mode and allow it to sync. This should do it. I always works for me. You usually only need to pair once and every time you use the headset all you should have to do is connect it. I hope this works for you. Good Luck.

It might already have been figured out but if you hold the answer button on the headset down until the light stays on steady, it is in pairing mode. You can then go to bluetooth setup on the Curve and it will find the headset.

I figuered it out.........you have to push and hold the BT button down as the phone searches for it. Good to go.

SOURCE: I have a H270 Bluetooth headset. I charged it

I had the same problem. I plugged a USB charger into the headset and turned the power switch off. It worked as normal after that. I think it does not like to be "on" when the USB is disconnected. Anyway it seems the plugging/unplugging kick-started it.
