Haley, I have never done it, but it does not sound too hard. Read through the following links below to find out how to hook up wireless head phones.

How To Connect Wireless Headphones

Opened up one of the earcups and dont ask me how it was just by force. The cable that connects the 2.5 to the speaker is frail and there is quite a bit of shielded cable that can rub against each other over time. I fixed it by removing the cable and soldering in two separate cables of similar size.

I believe this monitor does not have a built-in speaker. If you have the optional hang-on speaker, it must connect to the laptop's speaker/headphone port (speaker's green connector cable/plug). You cannot use the external speaker and the headphone at the same time unless you are using a Y connector cable.
This monitor has a VGA and a DVI-D ports for video input. Neither supports sound.

Could be. No battery has a lifetime forever. But perhaps you did not unplug it correct?
Try plugging it in and look if any light goes on when plugged in on the charger. You don't need it on the charger for a long time. Then unplug it an try to start it again. also check if all contacts on the Jabra and on the charge cable are clean and nothing can block the current.

Some stereo system have the ability to switch off the speakers when playing via headphones. In others the headphone socket itself does the switching. However headphone sockets can become faulty and when the headphone plug is removed it doesn't restore sound to the speakers. It's very easy to fix this, with a check that the contacts are not bent out of place. Or you can rewire a new headphone socket, making a note of the wire connections before you replace it.
Sometimes it is quite difficult to get the speaker cable to make a good contact with the speaker sockets. You should check that they are making contact.
To test any loudspeaker just connect a 1.5 battery for a short time across the disconnected speaker. If working the speaker will pop!
As the sound is going to the headphones the amp seems to be OK and one of the above options should correct the problem.

Make sure that the cable on other ear is not loose, if not there is a wiring issue.

You may need to change your output sound device. The method may vary depending on your software and hardware, but go to Start -> Control Panel -> Sound (I think. Doing this from memory, so might be slightly off). There should be a Devices or Output tab. Change that to your bluetooth headset. You will probably need to restart WMP before you hear music, too.

someone just gave me a hotfix from MS. works great!
