The red light does not come on when I charge the headset from the mains charger the charger is working

Leave it plugged in for 4 hours. Yello should turn red then green when fully charged

Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.

8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

Normally if you have a VXi, B250-XT on its charger and you are seeing both a Green and Red light the headset is changin over from charging to fully charged. The headset is designed to be able to use while it is on the charger however once you place it on the charger you must turn it on to reconnect to your phone before you can do this. Put the headset on and press the Multifunction Button for 2 to 3 seconds, you should hear two rising tones and the headset should reconnect with your phone. Note* your phone may require you to accept the connection request.
If the headset will not turn on either on or off the charger I recommend calling VXi at 800-742-8588 for warranty repair information. A headset that will not turn on indicates the unit is having an issue with one of its control circuits.

Dear Allen
Im strongly recommend you, buy a new original charger otherwise you can damage your headset.
The red light you saw probably because your charger is not compatible.

You can buy a new one via eBay.

Sometimes it takes longer than two hours. Leave it plugged in overnight if you can. The indicator light should go off after fully charging.

I think the charger is the problem. I ordered one of these and then it wasn't charging the day I got it....it's supposed to go from red, to orange to green as it charges, but the red LED just goes off after a while, before the headset is fully charged. I solved this by charging it through a USB-to-miniUSB cable on my laptop USB port. This worked beautifully....unfortunately I think the H700 chargers are faulty.

just open the main board
and clean with solution
and give a little bit of heat with smd
