Relying on a codec, which intrinsically plays priority on the basis of specific frequencies, is intrinsic to the limitations of using low-energy radio waves in the UHF range. Codecs are for phone calls and data packets, not full spectrum audio. That doesn’t solve the issue, it just slaps a bandage on it so it’s less noticeable. If I need a larger spectrum, rather than a patch of bass and treble, Bluetooth continues to fall dramatically and irritatingly short.
I’m glad it works for your purposes, though. I do not mean to come off like a jerk; I just prefer dedicated bands for anything wireless that cover a wider range.
