Full Duplex Bluetooth
[QUOTE=CZ Eddie;49134336]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.

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.

I have a similar question.

I need a Bluetooth adapter (transceiver?) that supports simultaneous use of mono earphone and microphone. This is surprisingly difficult to find.

It doesn't matter if the earphone and microphone are on the same line. It would be cool if each had a separate 3.5 mm jack, but I think such a Bluetooth adapter does not exist.

As CZ Eddie indicated, there are units with the microphone built into the adapter itself, but I would like to keep the adapter discreet (e.g. not clipped to my shirt). Hence the need for a separate mic line.

The closest I've found is the Blue-Wi Nighthawk ( The primary mic is on the unit itself, but an external mic can be added through the 3.5 jack as part of their "Connect & Go" system ( What's not clear to me is if that jack can be used simultaneously for both earphone and mic.

PrymeBlu ( looks like a very similar system to Nighthawk.

I'm really surprised this is so hard to find. It looks like 99% of wearable Bluetooth adapters are designed for output only.

Any ideas greatly appreciated!
