[@adox66]

So ironically it’s quite an Apple type move where the listener is locked out of controlling the codec selection. My read from this video is that lossless just can’t be consistently stable over Bluetooth so the best you will get is the occasional lossless playback in a adaptive variable playback that you have no control over and is marketed as lossless.

[@NostalgicMem0ries]

imo its ldac alternative, as ldac scales down and up, same with aptx now, just qualcomm named their perfect condition loseless, sony could have done that too, but they didnt.

[@JensVesterChristiansson-wr4lz]

In Sennheiser momentum 4 true wireless app you can select the codec, either Aptx Adaptive or Aptx lossless, and afterwards in android developer settings you can for Aptx Adaptive select the 48 or 96 khz.

Nerdy? Yes. But, I enjoyed it very much. And I’m an iPhone user. Which I heard the disclaimer in the beginning of the video, yet I watched it all the way until the end. A testament to how interesting and informative your videos are. Thank you.

[@deiruch]

Some clarifications: 1. SBC is adaptive as well, not only LDAC. SBC codes adjust the "bitpool" parameter, depending on the connection. 2. By default, most SBC codecs are configured with comparatively low quality settings, but we can adjust parameters. I currently run SBC at 684 kbps. It's easy to run SBC at higher rates as well, e.g. 990 kbps, but at some point you run the risk of producing dropouts when you hit the bandwidth limits of the Bluetooth connection. 3. LDAC fares worse in listening tests, compared to SBC-With-High-Data-Rates and/or AptX. Don't use LDAC. 4. Some codecs, like AptX, compresse audio data not by removing content, but by increasing noise. LDAC and SBC remove audio data.

In my experience, LDAC has been a game-changer. It's been the most reliable for sound quality and constant uninterrupted connection which was something that plagued my many other Bluetooth headphones/iems. I also agree that the hardware makes a bigger difference. For me the now old Sony WFXM3's are just unbeatable! I love them and they can be had for so little now relative to their new price.

Yeah it was nerdy but really liked it. Kinda confirmed all my suspicions. To get real lossless on wireless there are just too many factors in play (phone, IEM/headphones, software, bluetooth chips and the air in between). So wired for quality and wireless for ease of use it is 😊

Great video John. Not in any way confusing. I assume requirements are BT 5.3, Qualcomm Snapdragon, and the phone manufacturer to pay the appropriate licences. Samsung only pay for APT-X. Never APT-X HD or above. Because they have their own high quality codec... Would be good to tell your audience about this... They are a major player. Can't install a better codec either..

[@JensVesterChristiansson-wr4lz]

@DarkoAudio the Sennheiser momentum 4 true wireless control app allows you to select either Aptx Adaptive or AptX Lossless. If you after selecting Aptx Adaptive go into developer options you can select the bitrate to be either 48 or 96. In the Sennheiser control app select Aptx lossless and in developer options you only have 44.1 khz available. Funnily enough both have in developer options only 24 bit available and they are both called Aptx Adaptive. The Aptx Lossless should be 16 bit so the 24bit is a bit weird but if I get better lossless dynamic range who am I to complain. Another thing is that you can only play Hi-res 96khz files bit-perfect if you select Aptx Adaptive. AptX Lossless does not play files higher than CD-quality, but it plays CD-quality streaming very well.

Excellent explanation ofJohn thank you, as a Sennheiser user I can say there is a notable difference between the two codecs Aptx and Aptx Adaptive. I recently started using the BTD600 dongle so I can extract every ounce of sound from my Momentum 4 since it enables the full AptX suite and you can even FEEL the difference.

[@karlh]

I find it funny that these manufacturers mention codecs so much in marketing to promote their earbuds, when the difference is as you said in the video is practically inaudible, because of the limits of sound quality you can get in ~300$ wireless earbuds. I use Sony's WH-1000 XM5 headphones (that should have a much better sound quality than all current wireless earbuds), with LDAC on my phone, and I can ever so slightly hear a difference between a CD-quality file and a 320kbps mp3 one if I'm in a quiet environment and raise the volume a lot.

[@DraconicA5]

This is true. The difference between lossy and lossless is only noticeable in an ideal environment and when you fully focus on the audio. This is why audiophiles haven't always offer the most reliable advice. They also ignore the advantages of EQ, focusing solely on the unaltered initial audio performance of their headphone. 🙄

[@ernestwong3872]

AptX Lossless is an extension of AptX Adaptive But the problem is unlike LDAC, you have no control to enforce it running at lossless mode. They rely on the Qualcomm software solution for picking up the right mode which is unreliable in my own experience. Using Pixels as test source is a complete failure as well as it can't offer Android SRC bypass like Sony Xperia with her own music app. It is locked to 48KHz. So you are lossless in the codec but subject to SRC loss which completely lose the point.

At first, I attributed all of this excellence to aptX adaptive; but gradually, when I played those same songs from devices that did not support aptX adaptive, I realized that the hardware of the ZE3000 was as much in play as the codec.

I love your videos and the effort to decipher the madness that is hi-res/lossless streaming over Bluetooth! I own all three earbuds as well as the Zenphone 10. I found to consistently stream 44.1khz on the PerL Pro I had to disable Aptx Adaptive Hi-Res 24bit 96khz streaming in the Qualcomm settings in Bluetooth settings. But even then, when I enter developer settings it still shows the connection is 24bit not 16bit. So yea even more confusing but basically I agree, going from regular Aptx to Aptx lossless is the slightest improvement. The same difference using the Denon PerL pro on my iPhone 15 pro with AAC vs Aptx Lossless.

[@mcnaugha]

Just read the article on the Zen Blue 3. Firstly, comparing the Bluetooth bit rates between different codecs and then to audio file formats is completely nonsensical. They are not comparable. The bit rate specified for a file format is the speed at which it needs to be read from local storage to playback without skipping or dropping out. It has nothing to do with what happens with Bluetooth. It would be about the speed it would be read from memory after the Bluetooth transmission is over. Bluetooth transmission rates are more comparable for their likely impact to energy usage and heat dissipation. They differ because their algorithms are different. Not because they’re telling you how much they’re throwing away under lossy conditions. The algorithms are usually proprietary and we don’t get to know exactly what they’re throwing away. So, comparing LDAC’s Bluetooth transmission rate with the read rate required for a FLAC file is like comparing apples and oranges. Even aptX Lossless shows this because it transmits at 1.2Mb and you need 1.4Mb for a 16-bit/44.1kHz AIFF from a CD. That’s the other thing John missed from his list of reasons to rain on aptX Lossless’s parade… it also only works when fed 16-bit/44.1kHz lossless sources when using the Classic Bluetooth variant. It supports 16-bit/48kHz when using the LEA variant, which is don’t think anyone has implemented yet. It does not convert other sample sizes/rates for lossless transmission. So, 24-bit sources will only be able to avail of lossy aptX Adaptive. They claim this iteration of aptX Adaptive delivers 80% of the original audio data but I’m not sure if that covers all sample rates up to 96kHz or it just covers 24-bit/44.1kHz. Also, the article doesn’t mention the Zen Blue 3 does support Bluetooth transmission. It’s not just a receiver. So, it could be useful for taking an analog source and transmitting it over aptX Lossless. That’s provided iFi’s ADC is supplying the analog audio as 16-bit/44.1kHz. Of course, you can use it with earbuds that support aptX Adaptive and aptX Lossless. It might also have been worthwhile mentioning that the FiiO BT11 USB-C dongle is coming soon and it also uses the QCC5181 and is compatible with all smartphones including the iPhone. It promises LDAC. We’re not sure if they have licensed aptX Lossless on it. I’d be surprised if it doesn’t support aptX Adaptive. The FLOOGOO FMA120 supports aptX Lossless and is available now but it’s a little less convenient as it’s a USB-A design. It’s intended for use with desktops/laptops but should work on anything supporting USB Audio 2.0.
