Soundpeats Q12 plus earbuds are aptx LL and $23.79 right now on Amazon. I prefer using the on board speaker or wired headphones on the nox but when I dont they are one of the cheapest wireless alternative for my 600 nox. Not a fan of the bluetooth audio on the nox at least with the wireless headphones Ive used
search Miccus SR-71 on Amazon.
Same as the pair that comes with the EQ 800. I bought them after I dropped my originals on the concrete for the umpteenth time and something finally broke loose inside them.
