There MUST be an available piece of hardware to do this. I know it's more than converting the plug size and involves impedance matching and stereo-mono stuff, but doesn't SOMEONE make a box that will let me use my cell-phone in-the-ear hands free headset on my laptop for skype?
If there isnt it seems like a great market for one!
Traveling with one of those lame call center looking headsets in your laptop bag isn't cool and you'll have a hard time picking up any chicks at the airport/internet cafe with that on. :) I've only found one place that sells something reasonable, haven't bought one yet myself, but will before I travel next time, basically it's a mobile phone style headset but with PC style connection jacks:
They're in the UK but the total shipped to the us is ?4.95, which is about $9.00, not bad. You can forget about the part for "VAT" because if you live outside of the UK they won't charge it and I doubt the US customs henchmen will add any import tax at that low of a value.
If you do buy one I'm curious how long the lead is. The person who responded at babble.net when I asked apparently doesn't speak english well enough to understand: "How long is the cord on your babble-bud headset shown in your web store?".
There are different hands free units with different specifications. I have monstly played myself with hands free units made for Nokia cellular phones. At those hands free units, the headphone part is 32 ohm spaker element similar to ones used on normal headphones. This can be directly wired to line/headphone out of the soundcard directly. Because there is only one speaker, you cna wire it directly to only one audio channel (left or right). The microphone in the hands free unit is pretty normal electrt capsule that can be wired directly to PC soundcard microphone input (signal wire to tip and ring of 3.5 mm plug, ground to connector ground).
Maybe some day I have time to add some building details to
I don't kknow any such box. The reason why such box does not exist is that there are so many different cell phone hands free units that use different connectors and have different technical specifications... Different hands free units would need different conversion box.
I do not have any ready to build device to recommendation. Biltema
sells one unit "MULTIMEDIAHUBI" that is designed for controlling audio volume to speakers, switching between headset and spakers etc.. Details at
unit has a 2.5 mm jack which according the manual / print on the case would be for interfacing hands free unit... Good idea. THe sad fact is that it does seem to work with any hands-free unit or similar... I have tried several different models for this.
Soldering has never been a problem for me... And I have made this king of interfacing from component when Ihav had need for it.
