I have had to attend conference calls. And I dont have a telephone headset. That is a pain. It requires me to hold the handset in my hand or use my shoulder to keep it pressed against my ear.
However I do have a pair of computer headphones. So is there a device that plugs into the telephone where the handset connects and provides a line-out on the other side, allowing me to use my headphones? This would be useful gizmo. Telephone headsets are expensive, headphones I can get for Rs.100 also. It can also have a line in and a built in mike that can come into play when line-in is not connected.
Also, I can connect a wireless headphone transceiver to the 'device' and walk around during the call...maybe take the call from the 'comfort' of the loo. :-D
BTW this is the right way to attend conference calls. ;-)
