HS850 microphone problem (other party can't hear)

I've been having increasingly frequent problems with the microphone on my headset - and it sounds like this is a fairly common problem based on other problems posted. The person on the other line can barely hear me, if at all. Sometimes the sound is a little garbled, but mostly it sounds as if only 1% of the possible volume is coming through. The problem probably started as long as a year ago, but has only become a real problem in the last two months. I have been using this headset regularly for nearly two years. Unfortunately (?) the problem is intermittent. It will be fine for several days or a week, and then it stops working. Or, it won't be working, and I'll try again, and it does work. I have tested the problem out by using the headset with the voice memo function on my phone; indeed, this was the only way I was eventually convinced that my family and friends' phones weren't POS :) I have tried many different combinations of deleting the profile, re-pairing with the phone (a Motorola e815), power cycling the phone (with and without battery). I also opened up the microphone portion because a user on amazon reported that his problem was fixed by soldiering a loose wire, but mine did not appear loose. There is nothing blocking the hole that leads to the microphone. I gently removed the mic portion from the silicone piece and nothing appears to be physically damaged. I just would like to find out if there is anything else to try before giving up on this headset entirely. When it works, it's great, but the growing unreliability is making me annoyed.

Re: HS850 microphone problem (other party can't hear)

It sounds like a short in the headset wiring.

I understand you have checked the solder joints. However, the short may still be at any point(s) along the length of the cord. Sadly, shorts will eventually occur in all wires that are moved regularly. The solder joints is typically the first place that happens.

Try using your headset on someone else's compatible phone.

I have explorer 240. I paired my device to computers bloutooth. everything was ok. But now the other party can't hear me. I tryed to pair with my cellphone, and there was the same problem... Is there...

It could be that your unit is defective and may need to be replaced but here is some information for you to check out from the user guide:

1) Callers cannot hear me, or I cannot hear caller/dialing tone.
The headset is not turned on or the headset is not connected to mobile phone. Press the call control button for 2 seconds until you hear a beep or see the indicator light glow blue to turn headset on.
Your headset is out of range. Move the headset closer to the phone or Bluetooth device.
Your headset battery is drained. Charge your battery using the AC power adapter supplied.
The listening volume is too low. Press the volume key up (toward the earloop) to increase the sound heard in the headset.

Good luck from Headsets Direct!

Echo when using HS850

It might be a problem with their sound setting. If their speakers are on while using the mic, they might get some feedback that could be the cause of the echo. They may even just have to tweak their mic settings (through the control panel sound options or their soundcard options).

Motorola HS 850 Mic is not working.

perhaps it is in "mute mode" which can be activated on the headset itself by simultaneously pressing both the up and down volume buttons. Also, have you tried deleting the device from the phone you are using before you pair it up again? finally is there any firmware/software update available for the phone? This can be the case frequently with bluetooth problems with Blackberry devices (I know this from painful experience with this same headset). Good luck.

Whats most likely wrong with your HS850 is the connect button on the front of the headset (the larger oval chrome one with an inlay of a traditional phone handset on it)is stuck down. To repair this you will hold the hand set and pull up on lanyard attach point firmly. (This facia is held on by double sided tape). After pulling the facia you need to purchase or borrow a T-6 Torx bit to remove the screw that holds the headset together. Once you get to the circuit board you will see what the button and spring assembly are (all is is a round piece of foil and the "spring" is a piece of tape using tension to pull the foil up!) Reset the piece of tape so it does not rest on the board and reassemble that headset. Enjoy your HS-850
