If the KZ AZ09 Pro were AptX Adaptive, it would advertise this trademark under a license. It is AptX/LL. It is not AptX Adaptive nor AptXHD. It does advertise "High Definition" AptX...but this is marketing 101. Play of words. Easy to verify on my BTA30Pro in TX mode. If it were AptXHD, the indicator light would glow YELLOW. However, it glows PURPLE...meaning AptX.the thing is that theres also the CCA BTX which seems to be very similar to the AZ09 pro, both having the QCC3040 chip,
But the CCA appears to be aptx only while the AZ 09 pro is APTX adaptive.
BTW. how is the KZ cable connector called and what brands support it apart from KZ and CCA ?
That being said, I use my modded AZ09 Pro's (C to B pin mod) with my S12's most every day and have had excellent results across the board for the better part of 2022.
For the LL mode...three successive clicks to the RIGHT earhook button
For Power mode...three successive clicks to the LEFT earhook button. This mode I often use with the S12 to bring out the bass in this planar. Power mode does reduce the battery life by 15%...but this is from what is already ample battery life on the earhook (~8 hrs).
