Kitsound Bluetooth Adaptor
It could not be easier to set up, all you do is take it out the package and put it onto the Bose apple connector and pair it with the music source and that's it. It took all of 20 seconds.
Sound quality and connection stability is flawless. Range is at least 15m, beyond that I don't know because I ran out of garden.
Delivery time was 3 days by post from order.
In short it is that rare thing - a bit of kit that meets and exceeds expectations.
If you want to convert your speaker dock to Bluetooth buy this one, it works.
