Blinking green light on microphone, headset not working

Blinking green light is an indication the headset is trying to establist communications with the receiver (dongle). Sound issues are normally on the side where the microphone is, this is most commonly a broken wire. The speaker wires are very small diameter. This can be fixed by a competent soldering job with new wirest from PC board to speaker inside the headset.

No green light for QC2, just red. If it's constant the battery is charged, powering the noise cancellation, and, if connected to an audio device, conducting sound. If the red light is blinking, the battery is losing its charge.

U must RESET the Headset.
Switch OFF the Headset.
HOLD the answer/end key + power key (for about 5 second).
Red + Green indicators lights start to alternate.
Then Ur Headset is RESET.

Connect / Pair it with your Mobile as normal.

Did you find the solution, I have the same issue and the Leadsinger company is not a verry serious company no one knows about this and no one can help! Thanks Cathy

open and, replace the rechargeable batteries

The compatibility setting, in almost 100% of the cases, should be set to "1".  You can find it on the side of the base, it's a little turn wheel that will turn if you stick your thumbnail in it and twist.  I have seen one instance on the Cisco IP phones that requires the compatibility setting to be on 5, so try that as well.
If you have a lifter installed, make sure that the short telephone cable that comes out of the back of the headset's base unit is plugged into the handset port of the telephone (where the handset coily cord is normally plugged into).  You would then plug the handset coily cord into the front of the headset base unit.  Make sure you have that configuration, and try again.
Finally you can try a re-set.  To do this you should lift the headset off of the charging base, make sure the green light on the top of the base is off (the headset is off), and then do the following: 1. Hold down the mute button and the call answer button at the same time. (The mute button is the black little wheel on the top of the headset itself.  If you use the tip of your finger to push that straight in, it will mute the headset) 2.  Keep holding both buttons down until the green light below your thumb on the headset flashes for 2 consecutive series. 3.  Let go.  Wait about 20 seconds then try answering.
If this doesn't work, try a re-subscription: 1. Place the headset back on the charging base. 2. The two microphone volume adjust buttons on the back of the BASE unit should be pressed together.  This will start the red light and the yellow light blinking on the front of the base unit. 3. Hold the mute button down while the headset is still on the charging base.  Hold it down until the red light stops blinking. 4. Disconnect the power to the base so that the red light and yellow light turns off. 5. Plug the power back in after about 5 seconds of it being disconnected and make sure the red light on the front of the charging base is now solid and the yellow light is flashing. 6.  Pick up the headset and try again.

Try a system reset:
1. Lift the headset off of the charging cradle (the base).  Make sure the headset is turned off.  The green light on the base won't be on if the headset is turned off. 2. Hold down the call answer button on the headset at the same time as mute button.  The mute button is found on the little black wheel on the top of the headset.  Use the tip of your finger to push it straight in. 3. Hold both buttons until you see a green light on the headset flash.  It will be right below your thumb.  Hold both buttons until the green light flashes for a series of 2 flashes.  Then let go of both buttons. 4. Put the headset back on the charging cradle and wait 30 seconds.  Lift it back off and try again. 5. If this doesn't work repeat the process once more or try a resubscription.
Resubscription procedure:
1. Put the headset back onto the charging cradle.  Make sure the red light on the base is on and the yellow light is flashing. 2. On the back of the base there are two buttons for the microphone adjustment that can be pressed down.  Press both of those down until the red light and yellow light on the front of the base start flashing. 3. While the headset is still on the charging cradle press and hold the mute button until the red light on the base goes solid, and the yellow light stays flashing. 4. Unplug the power to the base and then plug it back in. 5. Wait 20 seconds and try.

just turn on bluetooth in ur mobile and then turn on ur bluetooth headset by holding the power button for atleast 5 sec and if blinking green light show up it means that it is turned on,if it shows blinking red and green then it is ready to get paired with ur mobile phone so u can straight away connect the bluetooth by selecting handsfree and new device and in the list of divices select hbh608 and get it paired.if it shows a blinking green then hold the volume increase and decrease button at the same time for 5 sec and then the light turns blinking red and green and then u can go to handsfree and new device and select HBH608....its easy try doing that...it workss....

It sounds like you need to re-register the earpiece to the base. To do this, use the following steps:
1. Return the headset to the
Headset Docking Cradle

2. Press and hold both the
Speak Volume Adjust Buttons (+/-)
on the back of base unit for a
minimum of 5 seconds. The
Red Power Indicator will then
flash

3. Press and hold the Headset
Mute Switch (black button on top
of earpiece) for a minimum
of 5 seconds. The On-line
indicator (green light on boom)
will then illuminate.

4. Subscription completion is
indicated when the Power
Indicator is fully illuminated
and the On-line Indicator is
extinguished.

5. If subscription fails within 2
minutes the headset will return
to the un-subscribed state.
