Why does my Motorola S9 only play out of the left ear when connected to my laptop? It connects to the pc fine and the most updated software. Do I need to buy a stereo dongle?

I just had the same issue. I charge my headset every day so I came to the conclusion that the short was due to a small piece of metal shorting out a connector in the chargeing port of the headset. I fixed it by first opening the charging cover and holding the headset by the ears in one hand. I then lightly tapped the opening against my other hand to loosen the metal shard. After doing this a few times, the sound came back. I then used a can of compressed air to finally flush out the intrusive shard. I didn't see how large it was but now my S9-HD headphones work! I'll check the connections on my 2 chargers to see if they have any evidence of breakage because I did notice when I plug in the set, I have to jiggle the connector a little recently.

I've got a driver from lenovo and it worked great controls work fine and u can answer your phone, music pauses and resumes after u hung up sound a+ driver is called: 7zbv14ww

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.

With software (US$ 28 app)... Works fine, but is shareware...

does your laptop have a2dp bluetooth profile

this profile is needed to play music

does the other buttons work play pause
if not then your phone most likely does not have

Audio Video Remote Control bluetooth Profile (AVRCP)

Returned the motorola back to the store and got another brand. Did the full install (add Bluetooth) Had same problems.

My solution Was to go into Control Panel select speakers. Make the bluetooth speaker default. Check its properties (Level). and test (tones should play through headset).

Now restart your application (Media Player)
I'm running Vista 64

I hope the resolves Motorola s-9 problem (It is a much nicer headset)

I had the same problem with a Samsung phone. There are two ways of fixing this; First, you can remove the S9 profile from your phone's bluetooth list, and then add it again, going through pairing and entering 0000 on your phone when asked for the code.
Alternatively, you might try pressing the "play" button on the right earpiece on the Motorola S9. This is supposed to kick it into the A2DP stereo mode for music listening.
Good luck.
And get a copy of the manual from the Motorola web site at http://direct.motorola.com/ens/s9/Headset_Home.asp I found this very handy for checking what the little flashing lights mean. When you get stereo reception, the little LED in the middle of the headset flashes green, not the usual blue and red and purple for voice calls. 
In case you didn't know, as a phone headset, with the microphone activated, you only get sound in your left ear, and the light flashes blue. For music, you get both ears, and it flashes green. So if it ain't green, you are in mono mode.

i dont know how to download music on the motorola s9
can u help me please

If your phone supports the A2DP bluetooth protocol, music you play on the phone will be heard in both ears of the S9 headset.

Voice calls are always in one ear only.
