What is aptX?

aptX is a compression standard for audio that maintains the full range of audio frequencies while still compressing the music into a bandwidth that bluetooth devices can handle. This ensures better sound quality, even over Bluetooth.

Are newer Bluetooth generations compatible with older generations?

Yes, if you are using an older generation of Bluetooth on one item, the second device can still pair and function.
