Question about Motorola Mobility MOTO W755 Cellular Phone
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.
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.
