Good quality. It's smaller than expected. Works well but in transmitter mode it doesn't reconnect automatically. In transmitter mode it shouldn't be powered from the same circuit as jack audio as it is causing static noise. External power source solved issue.
Great little receiver/transmitter. Big battery (you can solder in even bigger battery as there is a lot of room inside the case). Output is a bit noisy with highly sensitive in ear phones. Supports aptX HD as described.
