Motorola W755 2.5mm headphone adpater connectivity problem

I have a Motorola W755 cell phone. Among its capabilities is the ability to store and play mp3s. It has a headphone jack, but it's a 2.5mm, not the standard 3.5mm, so I bought an adapter so that I can use the more common 3.5mm headphones. The issue is this: there seems to be a "sweet spot", if you will, for the placement of the adapter into the jack (and possibly for the headphones into the adapter). When the adapter is in this sweet spot, the music will play just fine. If, however, the adapter jiggles around in the jack, then the phone will cut out of the music application and dial the most recently called phone number. I have tested this with various most recently called numbers, and every time the adapter shifts, the most recently called number is rung again. Also, if the headphones move past the nearly imperceptible notches in the adapter, the sound goes from stereo to mono to no sound at all (not in that order, necessarily).

Someone please shed some light on this situation. I would like to listen to music while I'm walking (with my phone in my pocket), but this issue renders the music player almost inoperable. The normal shifting of the phone in my pocket that occurs because of my walking bumps the adapter out of precise alignment within 10 steps. I can't find reference to this issue anywhere else on the internet.

    Exactly same description. I just got back from the verizon store, and they said . . . you just have to pull the plug out a little, and they didn't say anything about it calling people. But my phone does it, my dad's phone does it, and my brother's phone does it. They all have that problem. (They're all w755s)

It actually has to do with the 2.5 mm adapter. I had the same problem and went to buy a new one because I thought the adapter was bad. Went to Radio Shack and the guy said there are 4 wires within the audio input so that you can add a microphone too if you want. You have to buy an adapter that grounds that 4th microphone wire and it'll work just fine. I got the more expensive adapter (about $10) and haven't had the redial problem since.

Motorola S9-HD will not turn on or charge

I had this problem as well, and my issue stemmed from a faulty charger that came with my headset. I would suggest trying to charge your headphones with a different cable. I found that I could charge my headphones with the microUSB cable that connects my laptop to my external hard drive.

Iphone bluetooth problems

Unfortunately, the iPhone doesn't (yet) have such capability built-in. But engaging the iPod function to listen to music/video audio while a call is taking place will allow you to hear said audio. Obviously this is not an ideal solution. If your phone is jailbroken, there is a tweak to enable music to be played through the bluetooth headphones but it is low quality.

Play music, tv and radio through my bluetooth

The RAZR V3M doesn't have the ability to play music through any bluetooth device, like some phones. Thats not a problem though. You can purchase special headphones, made by motorola, specially designed for your RAZR from almost any Radioshack or other electronics store from $20-$30.

Blue Tooth Stereo Headphones and KRZR

From what I can tell and after researching the same issue it is the KRZR. I called both Verizon tech support and my bluetooth tech support.
There is no solution
If you notice some of the functions in the Blue tooth Pairing/connection menu functions don't even work. (The on off for instance and the settings) After it is paired. I tried my bluetooth with other phones and it works fine.
I am going to the Verizon store to complain untill i get a different model.

In short the KRZR software is defective
