For those who want to use a BT dongle that lets you use aptX on your iPhone, get the Creative BT-W6 over the FiiO BT11 for now. Sure, you lose LDAC, but the W6 just works. The BT11 is a struggle. App is terrible and it doesn't connect to some buds - like my Fokus Prestige. They do seem like a beta product and probably need a few more firmware updates, but at this point, maybe that will never help. When the dongle works, it works well, but the W6 works perfectly on both the Fokus Triumph, FoKus Prestige, iFi Go Pods and PI8. When they connect, they announce what codec you're connected as. Plus, the color scheme when switching between codecs are the correct colors. This is t the case with the FiiO. Also, nice to have a physical button on the Creative dongle. Sadly, the Creative app doesn't connect to them via my iPhone. Not sure if that even matters.
