BT 4.0 Headphones?

[JohnBrown]

A general question, not really related to Nordic, but...

I have seen several references to BT 4.0 headphones. I was under the impression that BT 4.0 didn't have a profile for audio streaming, and that the sustained data throughput was too low for audio. Am I wrong about this, or are the manufacturers of these products using dual-mode BT chipsets in Classic BT mode, but using the BT 4.0 label as a selling point?

This is the closest that I have seen for Bluetooth Smart and streaming of Audio. So I assume that audio streaming is indeed possible, however I cannot comment on the marketing methods of different headphone manufacturers.

[JohnBrown]

Well I assume that it's not possible, as the sustained data rate is not high enough.

I actually think it is possible by the BTLE technology but the standard implementations at this point do not support it and yes it lacks an audio profile , but it appears there is work going on in the Bluetooth SIG.
