Could you guys go to Android Developer Options and checking which codec options are available when connected to the Panda. Is Adaptive Aptx there or Aptx-LL?

Interesting. I wonder why I don’t see Adaptive audio on my v30. Maybe because I am on Android 9I don't have a Panda but my Asus Zenfone 6 (Android 10, Snapdragon 855) shows these bluetooth codecs as available:
I guess Qualcomm dropped the aptX-LL even from the chipset's drivers.

Aptx Adaptive isn't available on that many phones I'm afraid.

Also about the APTX LL...
Just what I thought since the Panda is using a newer Qualcomm chipset, The supposed replacement of APTX LL is mostly a dead codec, there's barely any source devices that uses it, nor is there any BT transmitters that supports it. Despite all that Qualcomm claims it can replace APTX LL.
Hopefully LC3/LC3 Plus will replace Qualcomms crappy polices since they are both standard codecs.
By the way, any opinions about aptX Adaptive vs LDAC? Why not just use LDAC as it is more broadly supported (at least in the Android e system)...?

Thanks! Yeah, I should have made my question clearer. For me only audio matters as I don’t use any wireless for video. But I understand how that could be important for other people!Aptx Adaptive is the ONLY codec that can currently handle HD audio with low latency. Perhaps only useful for watching blu-ray rips over bluetooth and alternating between HD audio and youtube videos with fewer issues.
LDAC is tough to beat for just audio though and Sony not charging fees for it helps.
But there may be too many codecs plus Qualcomm demands licensing fees. Just as aptx was taking off, here comes HD, then LL, and now Adaptive. Worse, there are actually TWO different versions of aptx Adaptive!! How bad is that when most of us can't even use the 1st version yet?

"aptX Voice is part of the second revision of Qualcomm’s aptX Adaptive codec. This update will also bring support for hi-res music playback over Bluetooth. aptX Adaptive r2 supports 24-bit 96kHz audio files by extending the codec’s bit-rate above 600kbps. Currently, aptX Adaptive caps out at 420kbps for 16-bit 48kHz quality. This is undoubtedly a welcome addition for the audiophile community, although there will probably be a little wait for headphones sporting the updated technology.
Qualcomm’s latest aptX improvements require new hardware. Currently, Qualcomm’s Fast Connect 6800 chip supports aptX Voice..."
AFAIK, iFi's Zen bluetooth DAC is among the few claiming to support aptx Adaptive but I assume only on the receiving end.

For audio, only LDAC matters at the moment and when using at least the 660Kbps option. However, as stated before, LDAC mostly falls back to 330Kbps in which case aptX-HD is better (lower noise floor, better upper frequency extension). You have to force the 990Kbps option in Android's dev settings but then the connection becomes more sensitive to interference.Thanks! Yeah, I should have made my question clearer.

Panda on the receiving end shouldn't have much trouble but the smartphone/dap on the other end is the limiting factor (antennae implementation, chipset used, bluetooth software stack etc).

The best we can get with bluetooth right now is (almost) "CD quality"![]()
