Help Heard audio thru my bluetooth headset

While driving, I usually plug in my Moment to my car's auxiliary audio and listen to the music thru the vehicle's Bose system. For calls, I have the phone paired with a Motorola H3 bluetooth headset.

Today while listening to a song, the voice button on the right got accidentally activated. Then I got a blank screen which lasted a few seconds and after that I got a "Force Close" message. I clicked "OK" and lo and behold, I could hear the music playing in my headset instead of the car's audio system. I have been trying to recreate it and can't do it anymore.

Has anyone of you experienced this weird phenomena? It would be cool if I could consistently get my headset to act like a wireless earphone.
 
You cannot simply hook up a bluetooth headset to the Moment and hear music. I believe you will need a set of stereo bluetooth headphones in order for this to work wirelessly. :D

You are right. The only way to listen to music over bluetooth is to get a A2DP bluetooth headset. My Moto H3 isn't one, and that's why this experience was very interesting. It means there is a way to make a non A2DP headset pump out audio, albeit through some weird manipulation.

I think I know what it is... I don't use this often but when I'm on a call and want to check the quality of a video I start it playing on the call and get sound that way through the BT. I just connected it and tried to listen not on a call and it wouldn't play game.

If you hang up while still playing the audio it'll keep playing in the BT tho. On my old WinMo phone it'd always play media through the BT no matter if it was A2DP or not, just sounded like crap if it wasn't.

To be honest, the audio quality was acceptable, though not on par with a regular earphone. I will give your method a try and see if I can recreate it.

i've noticed that when i connect a ear peice vs. some BT headphones that one gets an aditional profile, "media audio" and "phone audio" so i did some research. adroid uses a2dp (advanced audio distribution profile) there are actually more than one profile in this profile.

1) thing to keep in mind "A2DP was initially used in conjunction with an intermediate Bluetooth transceiver that connects to a standard audio output jack, encodes the incoming audio to a Bluetooth-friendly format, and sends the signal wirelessly to Bluetooth headphones that decode and play the audio. Bluetooth headphones, especially the more advanced models, often come with a microphone and support for the Headset (HSP), Hands-Free (HFP) and Audio/Video Remote Control (AVRCP) profiles."
A) decoding needs to occur on the device, the more decoding that occurs the more processing that the device needs to have hardware capable of doing so.
B) the above is a definition of a headphone device. their usto be 2 different types of profiles offered for headsets and headphones, this got confusing really confusing when choosing a headset or headphone for said device.
C) because people would never actually need to use 2 channels of audio (stereo) or high quality sound for phone calls it was stupid to process all of that quality people weren't using only to drain the battery so quickly, they came up with a stripped down version of the headphone high quality profile, it's defining principle was that it was mono (1 channel) and low quality, to dramatically save battery and allow smaller size headsets.

2)headset profiles have a bi-directional (2 way) connection at all times and headphones only needed to have a uni-directional (one way) connection. if your headset is playing music through the car, and it is constantly listening to the mic, then it's constantly processing what is playing from your car speakers at the exact same time, and this would cause problems.
