Do you want to ask if Apple’s small tail decoder is effective for ordinary songs? It works.

According to the official website of the digital flagship store, to turn the rich lossless music resources in AppleMusic into high-quality music that can be heard by your ears, you only need to have a portable external audio decoder/headphone amplifier.

The Little Tail decoder is an audio digital/analog conversion and headphone driver hardware for the OTG protocol. It is small in size and usually does not have memory, battery and external power port. The audio data stream and power supply are taken from the HOST via USB.
