For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I’m excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.

LDAC is great, but simply stating that the encoder is “open source” is quite misleading (while technically correct). The codec is owned by Sony and heavily licensed. It’s a savvy business move of Sony to make the encoder free to use though, so everyone else can support their standard while charging manufacturers who want to integrate it into their headphones.
If we want a really free and open high quality codec, we should push for opus support via bluetooth
Yes… I made double sure to mention ‘encoder’ between that.
Xiph really won the lossy codec scene with Opus and I transcoded all my junk to that format. Hitting (my personal) transparency on 128k vbr is flat out impressive and it warms my heart that corpos won’t have a reason to collect taxes for basic things like audio codec. However it’s a different story with bluetooth audio codec in which I hope will change.

Same here. I’ve left myself a bit of a safety margin at 144k vbr, but having my whole library at transparent quality AND portable size is very convenient.
Though, now that opus 1.4 is out I feel a bit of anxiety whether i should re-encode everything from flac->opus1.4
Which tool do you use to re-encode everything to opus ?
I tried with ffmpeg and it works but I had many issues with covers.
Because 75MB an album is better than 400MB when you’re trying to pack them on a mobile device. Flac is for archival.

Isn’t the new default codec in BLE Audio LC3 free and open and high quality? And it’s required for BLE Audio support, so there will be more and more devices that support it.
LC3plus isn’t really HiFi. It’s designed to be low-complexity & low energy: https://hydrogenaud.io/index.php/topic,122575.0.html
LC3Plus is more then sufficient for transparent audio at the typical rates you will achieve with bluetooth, 160k is really low and you can normally sustain around 300-600kbps which is more then sufficient for LC3Plus. this test is IMO flawed for the intents and purposes for bluetooth audio
EDIT: LC3Plus caps at 512kbps, I cant remeber if that is before or after FEC (forwards error correction, not to be mistaken with PLC, Packet Loss concealment, FEC is kinda like raid, PLC hides dropped data)
Not anything to do with the LDAC codec but why does wireless headphones on windows suck. On linux (even a wm) I just turn on my headphones and it works, on windows every time I have to remove the device and add it back again
What about wireless headphones that don’t use bluetooth? I think I had some Logitech ones that did not use bluetooth. Are those a viable alternative to bluetooth on linux?
Bluetooth stacks are notorious for being gargantuan spaghetti code base. People have been trying to put out all those little fires because it’s more possible on Linux than Windows.
The standards are terribly complex and the reference implementations were originally written by the standards groups.
Then to keep compatibility everything has to be broken in the same way as the reference implementations which put more effort into “it works this time” than any kind of resilience.
I was trying to connect headphones on my partners Windows machine and it was a disaster. Most of the time it failed to pair, the rest of the time it paired but didn’t recognize as an audio device. We tried with 2 different devices and both worked perfectly on Linux and Android.
It’s the same for me. I thought it’s due to the motherboard I’m using, windows being the problem never crossed my mind. The only thing that worked well and didn’t have to be re-installed after a disconnect was the new xbox controller, so I feel like maybe there’s something fishy going on here.

I didn’t have the same experience at all. I’ve used a Bluetooth Xbox controller for years, and it’s worked great… As long as it was only in Bluetooth. If you try to plug it in, let’s say to recharge it or because you want a more reliable connection, you won’t be able to reconnect it in Bluetooth, unless you unpair the device first. Apparently, that is even the _expected behavior", for some reason.
The only way to disable that behavior is to go the the Windows device settings and preventing the controller from being recognized as a USB device, so it only uses the USB as a charging port. Another solution would be to connect the controller to a power plug instead of a USB port of the PC to recharge it, but how unintuitive is that? Imagine if Nintendo, Sony, Apple or even Microsoft themselves on Xbox pulled that? That whenever you plugged in your wireless controller to your device, it suddenly stopped working wirelessly? Out of all the smaller or bigger quirks of Windows, this one has been one of the most unnerving to me for a very long time.
Windows’ built-in bluetooth stack is famously bad. Try installing the Toshiba one instead. It’s a bit clunky UI-wise, but tends to have less issues.
I recommend you all to switch to Pipewire. Most bluethooth problems are fixed.
I’m so confused, please don’t confused a new linux user it doesn’t help me
Where the hell do you still buy Anker headphones? I’m in germany and holding on to my soundbuds flow because nothing else even comes close to comparison. I get Anker chargers and adapters and cables and whatever but nothing audio related to a point I thought they gave up on the whole branch.
They use the Soundcore branding currently for their audio products but it‘s the same company
Micro center carries soundcore products. Where I bought my current P2-L headphones, couple years back.
If you’re looking for a replacement for Soundbuds Flow (i.e. ~€20), you’ll be disappointed. For me, Soundbuds Flow were perfect for workouts. Cheap and I didn’t care too much about sound quality. Anker rebooted their audio line and focuses on mid-range to high-end products.
I have their Soundcore Space A40, and the battery life is legitimately amazing. The case lasts me a week of heavy usage, and the buds easily go 6-10 hours depending on how heavily I use the ANC. If the buds get low, tossing them into the case charges them back up most of the way in 15-20 minutes.
The ANC isn’t perfect, but it’s made my recent flights way more tolerable by cutting out most of the noise from the engines while still letting the voice of my seatmate through.
Sony did drop the ball with LDAC quite quickly, it could’ve been the new standard.
But with the release of the WH-1000XM3s (or was it the 4s?) they basically made most of the selling points incompatible with LDAC, so now almost no one uses it anymore.
Yes, LDAC and multipoint do not mix hence I’m looking forward to LC3plus that replaces it. To be fair it’s not a big issue to roll back to AAC or even SBC to use multipoint, because you probably aren’t gonna notice a difference when you don’t listen to high res apps like Tidal. It also should be known that a good codec does not fix mediocre drivers and/or chips. Regardless, Linux shines in letting you use a feature you did pony up for. :)
AAC hurts my ears. Not sure why since I can’t hear a difference between it and LDAC without listening very carefully, but after half an hour or so I need to switch it to something else because it becomes more and more uncomfortable.
Switching between LDAC/multipoint mode means rebooting the headphones and connecting them again, so it’s a massive hassle. That makes multipoint absolutely useless to me. I personally won’t be buying sony headphones (or anything else that comes with an app) in the future because of that.
I see, so Edifier and Soundcore shall do some homework as well: LDAC and multi point don’t work there either.
Oh LDAC conflicts with mutli-connection? That’s why I can’t get it on my 1000xm4?? It’s good to finally have an answer.
On my headphones, you can either use LDAC with one device or SBC/AAC with two devices. I can only change it via the app. Is there a similar setting for you?
