They are all based on the same chips. Any device will do.  Go for the cheap and cheerful one.

I have a BV11-40 and also a pair of H9i. Now need to use the headphones with the TV. Anyone able to recommend a decent Bluetooth transmitter that will do the TV and headphones justice?

Latency could be removed by using the speaker distance settings in the Beovision. 

I dont think so, with BT you would need to delay the picture. I.e a negative distance.

Which is basically what you do when you advance the sound, at least that is my understanding. When you enter distances in the setup for the speakers, you basically tell the TV to advance the signal to the speaker by the distance the sound needs to travel from the speaker to your ear.

When you add speaker distance in the speaker group setup, the sound on the speaker sockets will be ahead of the picture, and that can compensate for Bluetooth latency on the best Bluetooth receivers.

I think we are saying the same thing...

By default the sound will always be ahead of the picture since the image processing is significantly slower. However adding a delay to the sound data is pretty straightforward. Reducing that delay will increase the speaker distance, i.e the sound will be output by the speaker faster in order to compensate for the travel distance. However you cannot reduce the delay below zero since it is the fastest way sound can be processed. Thus your last remedy is delaying the picture, which is significantly more complicated, and properly why no Beovisons can support high latency modes of their own top speakers.

The BT audio link relies on a buffer to compensate for fallout's and provide a robust link, so as you mentioned, the better the design of the BT module, mostly the antenna actually, the lower you can go in buffer size. The wireless earbud are especially susceptible this phenomenon since the rely on two BT links, the up link and the master slave link, 500ms worth of buffering is not uncommon.
