Do you or anyone here have suggestions on the happy versions of the standards and protocols that result in 'can't really tell a difference'? I tried a few years ago and my middle aged 14 kHz roll-off happy with v0 VBR mp3 ears could tell a difference, I finally understood what people were talking about with listening fatigue and the like. Now admittedly it's been a few a few years and my car isn't likely to be able to negotiate a happy protocol but I'd love to get a reasonably priced stereo bluetooth headset that sounded OK.
