What version of Bluetooth does this use (2.0 or 3.0)?

I don't know, and threw the box away already. If it makes any difference, I'm able to use a bluetooth 2.0 heart rate monitor and this at the same time.

The android version is 2.3.? It is not recent and there are no OTA updates for this model.

This would probably be better directed to 66 Audio for the technical aspects but my understanding is it is Bluetooth 4.0. Since nearly all phones/devices to which you would pair these would allow backward compatibility, it shouldn't be a problem. Bluetooth 3.0 and 4.0 are nearly identical except for the lower power consumption of 4.0. As the standby time for these headphones is nearly two weeks, my bet is 4.0.

I am never owned the 2.0 but I known those who have, and they all preferred mine, which was the 1.0. Hope this helps.

Nope, this version came with 4.1. The version without Bluetooth comes with 4.2. If you are into a bit of hacking you can put 4.2 on it with a custom firmware.

It will work with any bluetooth device. I use it with my touchpad all the time. As far as bluetooth 4.0 -- if it backward compatible to 2.0 I'm sure you're fine.

since this is a receiver I do not think it matters. The transmitter is the one that needs 4.0. However due to size and features I would think it would be 2.0 at its best. I have used it and did not hear any difference between this unit and my 4.0 headset with Bluetooth coming from pc audio.

As of 7 / 2013.... This headset was only compatible with USB 2.0 (not compatible with USB 3.0)

The one I received is V2.1 and will not work with the diagnostic programs. It connects Bluetooth but since it is v2.1 instead of v1.5 the diagnostic program is not able to get vehicle data. Just received the week of June 19, 2015 and is latest v2.1 but only v1.5 is supported by diagnostic programs.

Bluetooth is wireless.. you can still use an ax cable if wanted/needed for an older device

With the new update you can simply pair it like you would any other bluetooth device. It DOES work

I looked at the info on mine, and it said it was 4.2.2. I auto updates, but I couldn't find how to upgrade to 4.4...."It doesn't have Bluetooth...."

Yes, works with any bluetooth device version 2.0 and up. This was bought for my father in law and his phone is a 3 year old Android phone, and it works just fine. Just make sure the device you are connecting uses Bluetooth standard 2.0 or higher.

Try 0000 that's what two of mine used. I had and old Bluetooth that used 1234 so maybe try that also. Good luck
