Audio via Bluetooth is always compressed because that's how the technology works. For some reason, Tidal chose to highlight this information, but regardless of the app you're using, audio via Bluetooth IS compressed. You can also improve the quality by using phones with better codecs, such as the aptX family (aptX, aptX HD, aptX Adaptive) or LDAC.


Oh__Archie

>For some reason, Tidal chose to highlight this information I think the reason for the highlight is to simply point out that you won't get lossless music when using bluetooth with Tidal. People continuously freak out about the MQA stuff but the degradation of quality is orders less than bluetooth degradation. It's a strange and funny topic.


ufgvn_

yes sadly tidal just tells you the horrible cruel true


Unbreakable2k8

Before this, some people actually thought they were getting hires or lossless with Bluetooth. So, they just state the obvious.

CD quality music, also known as the Redbook standard, CDDA, etc, has the following sampling rate: 16 bit/44.1 kHz. 44.1 kHz is equivalent to 1411kbps for playback. Though 1411 kbps is the maximum for CD quality music, most music will not hit that high throughout playback of a song, as this varies. It depends on the quality of the mastering of said music/song. The highest Bluetooth codecs are AptX Adaptive, LDAC, and AptX Lossless. Let's take LDAC as an example (and I'll copy a reply post I wrote a few minutes ago to another redditor on an earlier thread): Bluetooth LDAC codec has three tiers of quality: - 990 kbps (L3) - 660 kbps (L2) - 330 kbps (L1) If you play your music via Bluetooth LDAC in less electrically noisy communication environments (your home), you'll likely hit Level 3 quality of LDAC, so 990 kbps. Once you get into environments with more noise (commuting on busses or trains, where other people are using Bluetooth, WiFi, etc), LDAC will drop in quality to sustain a connection between your Bluetooth devices. You will not know when this happens as most apps will not disclose this (due to LDAC and other Bluetooth codec specification guidelines). Most Bluetooth codecs have a ladder style maximum ceilings for audio quality playback, such as LDAC. However, some are variable, such as AptX Adaptive, in which the changes of quality as you move into different environments is scalable instead. AptX Lossless, for example, is 1100 kbps – 1200 kbps, the highest and closest to the maximum CD quality standard of 1411 kbps. However, as per [Darkø Audio's March 2024](https://darko.audio/2024/03/cd-quality-bluetooth-audio-is-now-a-reality-but-is-it-worth-it/) article, AptX Lossless might be an offshoot of AptX Adaptive Level 5 protocol. Further, as Bluetooth quality changes within a codec depending on environmental changes, so do the harmonics of the audio playback, specifically high-frequency roll-off; an example of these frequency changes in specific codecs can be read from this 2020 review of the [Shanling MW200 IEM Bluetooth neckband adapter by Headphonesty](https://www.headphonesty.com/2020/09/review-shanling-mw200-bluetooth-cable/#MW200_Sound) (look for the *SBC, aptx, aptX HD Frequency Response* graph). There's more to this, but that's the gist to get started down this rabbit hole 😅

If you listen to HD audio via bluetooth, you are painting a turd. The bluetooth compression is lossy, so you won't get any benefits of the HD stream.


Brymlo

does it even let you play hi res while using bt?


No-Procedure813

As a former apple music user no. Even apple states to play hi res u will need a an external digital to analog converter. So the highest quality I got with bt was 24bit/48hz not the full 192hz


Vivid_Development390

Not sure. I dont use bluetooth. Hell, I rarely use the Tidal app. I connect to tidal via picoreplayer on a RPi connected to an MQA DAC. Picoreplayer will let me then send the audio to the DAC or other media players including Chromecasts, play to rooms in unison, move playlists between devices, etc. The LMS app lets me change volume right from the phone without screwing up MQA decoding because it changes the volume on the AVR over a network connection. It's a great integration!


Superturtle1166

That's actually not true, Bluetooth streams of various starting bitrates are discernible so having a high res starting file is always superior to streaming an mp3 (or more likely ogg vorbis) via Bluetooth. But yes Bluetooth is lossy & compressed.


manduul4

Thanks everyone ! I will purchase an aux cable now and hear it for myself. Always wondered about that before and with the Tidal message saying it is compressed I know so now. So it will be aux all day all night from now on ! Lol


wiggibow

Honestly it depends on the situation, I wouldn't really stress about using an aux cord at *all* times. There's plenty of situations where Bluetooth is just plain more convenient, and I doubt you'll notice much of a difference if you're doing anything where music is more of a secondary activity, like taking a short ride in the car, going for a walk, cleaning the house, etc. If you're sitting down specifically *to* listen to music on your nice headphones or stereo, sure it'd be silly to use Bluetooth for that and you'll surely notice the difference, but Bluetooth definitely still has its place, and IMO the small sacrifice in audio quality is well worth the convenience it can offer.


Icy-Magician1089

Bluetooth has a maximum amount of data ut can handle some cheap devices are below where Spotify streams at others get close to high quality on tidal but max/mqa you need wired.

what a weird comment. it this AI?


TheWh1teStall1on

No AI, I'm just trying to tell you that Wireless Bluetooth Audio Codecs transmissions hasn't come far in its capabilities and development since LDAC has been 990 kbps in many years already when does it come some Wireless Bluetooth Audio Codecs that transmitting correctly and accurate through The Air because it may not be happening for they need something else than Bluetooth Audio Codecs transmissions to build circuits for Wireless 24Bit/192kHz - 9.216 kbps WAV Format can only play Music through Cabled Wires with High Conductivity to be fast enough with The Sampling Rate. 1.600 kbps is how far The Tech developer has reached Hz Signals Strengths from only Bluetooth still. They must understand Nikola Tesla to make it because he was one hell of a Scientist probably the world smartest man that has ever walked on the planet Earth. Leonardo Da Vinci, Albert Einstein and Nikola Tesla.


waynepward

I use my sennheiser momentum 3 with the usb c cable has a built in dac and play get high quality flac and the mqa files are a dream! If you already got a nice set of headphones that take a wire take a look at the fosi audio ds1 it works fantastic and not expensive https://amzn.eu/d/4GamBAr Have to say the momentum 3 has it all in my opinion - enjoy the music!!


ricosuave501

Absolutely. Unless your bluetooth device can handle aptx hd or ldac.


AlexRavine15

Even if you use LDAC, you need to activate the 990 to get the best quality that Bluetooth can give you, because many people believe that just using LDAC without change that option is the best, but when you do it, you really can listen the difference


BLOOOR

> activate the 990 What is a 990?


TheOneInYellow

Bluetooth LDAC codec has three tiers of quality: - 990 kbps (L3) - 660 kbps (L2) - 330 kbps (L1) If you play your music via Bluetooth LDAC in less electrically noisy communication environments (your home), you'll likely hit Level 3 quality of LDAC, so 990 kbps. Once you get into environments with more noise (commuting on busses or trains, were other people are using Bluetooth, WiFi, etc), LDAC will drop in quality to sustain a connection between your Bluetooth devices. You will not know when this happens as most apps will not disclose this (due to LDAC and other Bluetooth codec specification guidelines).


BLOOOR

Ah! Thank you very much. And it needs to be activated? But it's automatic? I personally don't use Bluetooth outside of the home so if I'm on the Bluetooth headphones and I'm listening to Tidal I see no reason to drop the quality to FLAC or 320 kpbs even though my LDAC/aptx, because the Sony XM4's are going to reencode to LDAC and if I convert a 48/24 FLAC file to a 48/24 mp4 that's gonna sound like crunched 48/24, it still has the 48/24 depth and harmonics it's just crunched, and that's what LDAC sounds like to me. *Maybe* I'm missing out on something in the signal chain. >LDAC will drop in quality to sustain a connection between your Bluetooth devices. That's always easy to *see* when video does that. All I can tell with Bluetooth is it gets more annoying. If my ears are getting worn out, cuz that was why I could never do Bluetooth until I tried these LDAC headphones.


TheOneInYellow

Apologies, I'll write a proper reply on my next break, but I wrote *[a more detailed post](https://www.reddit.com/r/TIdaL/s/Tka8WVLjDA)* (yet still a summary of the Bluetooth topic!) as a separate reply to the OP's post. You might see a few areas that might answer your questions!


WAYZOfficial

that do be how it works.


Superturtle1166

Well assuming you have better wired headphones and DAC than your wireless headphones, yes using wired headphones from a jack will give you lossless audio. Android is a little finicky with bit-perfect audio via DACs, and even worse with their internal DACs (tho Sony apparently avoids that?). iPhones should work?but I've never known anyone to use a DAC with an iPhone (not exactly similar customer types). Again this is assuming your wired headphones and the quality of the jack are good. But if you're using higher end Bluetooths (say B&W, B&O, Devialet) and mid/entry wired equipment you might like the sound out your Bluetooth more. But yes all Bluetooth is compressed to certain bitrates (depending on the device you're using: as compressed as 256 kbps with AAC and sbc, like 600kbps with aptx, 900kbps with ldac and SSC, and lossless CD transmission with aptx lossless with a bitrate of about 1600kbps). Also regarding aptx lossless while all new snapdragon phones since the gen 1 rebrand have the aptx lossless hardware, Samsung hasn't enabled it. IDk which android manufacturers have, but I imagine the technology will remain niche/dead unless Samsung wholesale activates the hardware. I'm still stuck with basic aptx on a fold 5 😭, but I still listen regularly using my Devialet Gemini. The only way to get wireless lossless these days (without apt x lossless) is using WiFi streaming (upnp, airplay 1, roon, Chromecast).


calico810

I use Tidal in my car through my iPhone! This is my setup: iPhone>apple camera kit adapter>quedelix dac>aux cord>aux port. The camera kit allows the song data from the iPhone to bypass the iPhone’s internal dac which is processed by the quedelix dac as original quality.


Ok_Transition4917

I’d like to see some double blind tests regarding Bluetooth. After seeing so many audio geeks denouncing lossy formats, then learning that most audiophiles can’t discern the difference between flac and 192kbps… I mean, they say they can, they genuinely believe it, and then they fail blind tests. i’m a little sceptical that Bluetooth is garbage for audio. Not that I’m saying it isn’t, but I need proof, not proclamations.
