I'm probalby using the wrong words to google it? But I want a Bluetooth adapter that is capable of both 'receive' and 'transmit' at the same time. Or full-duplex.
I'd prefer it be an APT-X, but anything small with good battery life will do.

Why? Well, for a DIY project where I'll be using something like what you see in the pic below, to listen to my phone and make calls.

How about the Samsung HS3000? http://www.amazon.co.uk/gp/aw/d/B004...AC_SX110_SY165

Thanks, but that won't work because its microphone is integrated into the box rather than external like the boom mic you see in my pic.

That's true but from what I understand, if your headphones have a Mike, it will use that instead.

The HS3000 would be perfect if it did this. But I have googled for the last ten minutes and haven't found anything that suggests it lets you use an external mic. Do you remember where you saw this info?

Found one. And it took several hours of searching to locate this. So I'll post it up here in case anyone in the future needs something like this.

HTC BH S600 Bluetooth Stereo Headset

The built-in microphone is in the headset CABLES, rather than in the dongle itself.
So if you remove the headset and plug a different headset into the dongle, then the new headsets mic gets used.

The only problem is these are not super easy to find in the USA unless you want to spend more than they are worth.

So if i am understanding this correctly, you can unplug those headphones and plug in another set and now that set is bluetooth?

Technically, neither of the headphones are bluetooth. They are both corded.
What's bluetooth is what the headphones are plugging into. The tiny box.
So you can use any headphones in the world with this Bluetooth box. As long as they have a 3.5mm plug.
Impedance performance may vary of course.

That's probably the coolest thing in the world. I think I might be getting one! Bluetooth Sennheiser IE8s? HELL YES!

If those don't have a built-in microphone, then I would probably go with something different. The Samsung HS3000 has microphone built into the box and is an excellent choice for high efficiency headphones. Otherwise, it may not put out as much power as other alternatives.

It's the same deal. You can use the Samsung with just about any wired headset on the planet that has 3.5mm jack.

Full Duplex Bluetooth

Have you found a solution for this? I have been looking for some time for a similar DIY project. I have found one product from overseas and one in the US. The product overseas is about $270 with shipping and because it is overseas they won't accept returns. The one in the US has a PTT (Push to Talk) button that I would have to try and get around it.

I also found a device that allow you to either transmit or receive but that only gives you a simplex transmission from a headset. You can either talk to the person or listen to them, not both. I have a MultiPoint headset but that requires which device you want to be paired with.

If you already found something, I would love to hear about it.
