The advantage over the here and now and then mentioned Logilink Stick with APTX that the BTD 500 of APTX codec in Flash memory drive "wired" is. This means that the operating system is unaware of the codec and also does not have to worry drum (otherwise the Logilik, there the codec must be installed with APTX if you do not do what one hears even, but without APTX).
This is nothing to sneeze at, even under Windows, because one must look not dan sometime new codec driver.
