After much research, I recently purchased a pair of Sony BT-50 Bluetooth headphones. They are AWESOME!!!! The only problem is, there’s no way to mute them! In fact, there’s no way to mute any bluetooth headphones except from the ‘mute’ button on the bluetooth device. If you’re listening to music on a PC, volume up/down keys work (from a multimedia keyboard), but not mute. So I’ve written a utility that enables muting of your headphones with a global hotkey, and you can download it for free here.
Note: The program will only work on Windows 7, and you’ll need .Net 4 installed. So you know you’re on the bleeding edge of technology using this. Who knew a feature such as mute was so high-tech 😀
Btw, the BT-50 headphones don’t come with a USB Bluetooth adaptor, so if you want to use with with a PC (as opposed to a bluetooth-enabled phone), you’ll need to purchase one. I’d advise against going with the $1.00 bluetooth adaptors from China (even with free shipping, wtf?), and instead do your research and find an adaptor that has drivers for Windows 7 and A2DP support.
For Aussies, I can confirm that the Dick Smith Bluetooth 100M USB adapter (not listed on the Dick Smith website, but I found them in the Macquarie park store in Sydney) will work with these headphones, after you wrestle a bit with BlueSoliel (worst usability in software I’ve seen in a while – see below for how to automate connection of the Advanced Audio Service). And you’ll need to swap out the American power supply with an Aussie one – again Dick Smith has the goods. Just make sure the polarity is right: The engraving “CEN” on the jack with the yellow tip should be on the positive side of the connector.
Update: To avoid using BlueSoliel every time you switch on your headphones, you can save the connection as a shortcut. It is placed on your desktop without telling you:
