Impressively small, plectrum shaped device that both transmits from the headphone output of any device, iPhone, TV etc to your Bluetooth headphones. Again, as with my earlier review, there is a small time delay (latency) though less with this device. None-the-less, very useful - it receives too, so you can pump the sound from your iPad / iPhone (other devices / manufacturers are available!) through a non-Bluetooth enabled stereo or car-stereo.
This is stuff I like, old and new, that I hope you do too.
