Question about Motorola Mobility H700 Wireless Headset

1 Answer

Noise Cancelling distorts voice

My H700 works great when there is a quite background, as did the Samsung device it replaces. When there is any background noise, my voice is amplified and gets very distorted to the point where the person I am talking to can not understand me. Anybody know if this is normal or do I have a defective unit?

    Persons I am speaking with report distortions and echoing on the other end when I use the H700

    I ended up returning it. I believe the problem was actually with the BB 8830 which seems to have a very high level of automatic gain control even on its own mike. The phone will pickup a bird chirping at 500 ft. My guess is that the noise cancelling on the headset makes the automatic gain control on the BB go to maximum microphone volume which causes the distortion. Until the BB offers a setting to control this automatic gain, I doubt I could use any noise cancelling device. I am not sure this is even firmware controled so it may be something I will have to live with as long as I am using the phone. I just updated the firmware with a new release but don't see mike sensitivity in the available settings yet.

Try lowering the volume on the headset while using phone in quiet areas to avoid feedback.

Back ground noise


You cannot remove the background noise of already recorded material unless you have special software for that purpose. It is available, but costly. To eliminate some background noise, you may in the future, try to muffle the microphone by turning down the volume and recording by moving the device closer to the sound sources. Some folks put a wind sock over the recorder, as you may have noticed during TV News recordings on street events or at a studio. Try a wool or thick sock over the recorder and see if that helps.

H700 now only dials last number called


On mine, if I wait for it to be fully connected with the phone, then press the button one time, the blackberry ask for the correct voice command. However, if I press the button twice, it will dial the last number called.

H700 - microphone not working or am I on mute?


Ok here is the answer. There H700 have a small foam windscreen inside over the microphone that over time block the sound. The answer is to carefully open the unit and remove the obstruction and clean residue from the microphone and it will work like new. here is a link to pictures and instructions. http://www.geocities.com/jconkwright/H700fix.html

Will not voice activate


Does your Treo 700W support "voice dialing"? I searched the whole user guide for the Treo 700W and it does not say anything about dialing by voice. If the phone does not support it than no matter what Blue Tooth unit you use you will not be able to voice dial.

Battery needs replacement


Hi alvaring

Use a med/thin guitar pick and slip it under the edge of the casings and run it around the perimeter to snap open the casing locks. This method works for all snap together devices, and I have not found a better way yet!! Good luck. A FixYa rating would be great for this bit of knowhow..

A lot of background noise when playing back.


The pic looks like a TRC5880? If thats the case they are naturally quite noisey. The motors vibrate too much in my opinion. Theres not much you can do with it unfortunately. Suggest a new recorder or get that one repaired.
