My Sony NW-25 music player doesn't register Apt-X codec compatible with this product. It has been correct with all of my other headphones, including Sennheiser MM400-X (Apt-X), Sony MDR-1ABT (LDAC) and my Sound PEATS Q11 (Apt-X). I'm using my phone to connect to it and see if I can pull the logs of the BT transfer log and verify if the Apt-X is a false advertisement. If it is, it is a show stopper for me.
It'd be nice to know if they are or not.
