hi stefan,

sorry to let you know but sony w180 does not suort an A2DP profile,
which is necessary to listen music wirelessly. so u'll have to change ur handset if
u want to listen to music via ur bluetooth headset.!!

good luck!

try 00000 (five zero's) or 1234 or 12345; the first should work the others will work as well

I had a 9120 for years, great headset. Change the compatibility wheel and levels on the unit per the instruction book link below. https://www.jabra.com/_/media/Product-Documentation/Jabra-GN9120-Series/User-Manuals/User_Manual_Jabra_GN9120-GN9125_EN.pdf

If you haven't already tried this, disconnect the base unit from the computer and then see if the problem continues. If it does, there is likely a fault in the electronic switching in the base unit. If the problem doesn't continue, then it could be an intermittent switch on the base unit. You could try pressing and releasing the computer switch on the base unit multiple times. Maybe even lightly pry it up with your fingernail to make sure it's not stuck down. From my understanding any phone connection will override computer audio, so while on a phone call even if you computer beeps, it should not switch to computer audio. Hopefully this will narrow down the issue.

Many reasons that could be happening. Could need re pairingwith docking station, might need to play with the compatibility dial.

I found the manual!
