Question about Motorola Mobility H700 Wireless Headset

Problems w/H700 bluetooth

My H700 bluetooth worked fine for 6-9 months, then the person on the other end could not hear me.  I hear them clear, however the person I'm talking to says it sounds like I'm talking under water.  
I returned my bluetooth twice and got a new headset.  When I first receive the headset, it works perfectly, then again it works for 6-9 months and the problem occurs again.  Is anyone else having this problem?  What can I do to fix the problem?
It's frustrating because I've sent two headsets back.  If I send this one back, will I have the same problem after 9 months?

    I have the same problem, I've had mine for about 10 months and it worked perfectly. Now, the person on the other end can't hear me or I sound muffled. Help :(

    I have the same problem except that the problem occured earlier than 10 months (roughly 4 months). I had already exchanged one that didn't work and now this one has stopped working. For months I could hear people but they couldn't hear me. I won't buy another Motorola.

    Absolutely identical issue. Is there any other answer than buying a new one.

    I had the same problem. I was able to use mine for almost 2 years though. It worked fine and then the next day no could hear me at all. It was like the mute button was on. I tried muting and unmuting it but that did not work. I will try cleaning the mic with a needle. Hopefully that works. I was very happy with the device until now.

Try taking a small needle and gently clearing out the mike hole near the end of the boom. Anything I am outside and sweating a lot mine will clog up and I have the same trouble until I clean it out and then it's fine. Do not insert the needle in very far, all you need is to clear the outside opening a bit.

How to use my H700 after charging ?

If tv is bluetooth capable, look under menus and pair with H700.
Phones if initially paired will simply need to have bluetooth 'active' (as by default it is usually off). - If not pair - you will need to go through menus under 'settings' to pair with the H700 (also at this point indicate that the H700 is 'trusted device').

My H700 bluetooth, I can hear caller but they can't hear me!

The average life of a Bluetooth Earpiece is usually a few years. When you are having symptoms like you are describing it usually means that the Blutooth headset is at the end of its service life. You might want to cintact Motorola and see if they will Warranty them.

H700 is paired...I can hear the caller but they can not hear me? Any help would be appreciated.

I actually had this same problem within the 1st year I had my H700 headset. I had to carefully pry open the flip end and remove a small piece of fabric that had been put inside by the manufacturer. After I had done this, everyone I talked to when I used the headset could hear me just fine. I am not really sure why it worked since all I did was take out a tiny piece of black fabric but it seemed to. I was able to also close the flip end back up as if I had never opened it and it still stays closed. I have still been able to use the headset even after about 5-6 months later but I did get an extra headset to have around if I need it.

I can hear the person on the other end but they can't hear me.

To mute or unmute the headset, tap both volume buttons at the same time.

Bluetooth conection

This may not be the solution for your problem, but I'm sure you'll like the way I'm thinking... ;- )

I also have an H700, and the clearance from my cheek to the microphone aperture is small--maybe two millimeters. I've had a couple of occasions during the summer when I was working outdoors in the heat, and my sweat bridged between the mike boom and my cheek--my callers told me I was unintelligible. With the sweat wiped away and the mike aperture cleared, all was well again.

If you're sweating during use, that may be your problem. If it's a continuous problem, maybe you have something mashed into the mike aperture...?
