Bluetooth 5.1 vs 5.2 (And Why It's A Big Deal) 

That was truly helpful, quite digestible and cleared the field for me. Thank you very much for sharing your expertise, sir. Hope there will be more 5.2 stuff around soon. The year since you published your contribution seems to have done nothing for bigger market share of mid grade consumer 5.2 or even 5.1. I'd like to hve a BT headset with good sound and minimal lag in BOTH directions at last. I am using that Slipstream crap and I'm quite tired of it... Them Corsair folks feed very well on the lack of alternatives, which 5.2 could finally bring.

Answered a lot of questions I'd been wondering about. Excellent presentation, as always!

Thanks Franco. I just ordered the Sennie CX TW; my first pair of wireless buds ever. The videos I watched rave about the fact that they come with 5.2 but none of them say why it's a big deal. I got curious and stumbled across your tutorial. You have the kind of fluidity about it that can only come with expertise.

Quality video. Appreciate the help picking out new headphones bro!

I still waiting for audio routing options, so I can use 2different brand speakers and designate one L channel and R. I know some brands have links within their own ecosystems but I want my devices settings to be able to also route audio the way I want. Multiple channels and a sub woofer, I can make my own 7.1 surround sound with whatever compatible speakers I have laying around lol. I use iOS for music production and am worried about when Apple axes the usb c and lightning, latency is my enemy, I hope the Bluetooth tech gets fast enough for live music applications. Great video.

Excellent video, very clear and helpful, THANK YOU !

Nice job Franco, hard to find info, and easily understood.

that was a concise summary of exactly what would anyone want to know in this matter, clear and helpful. Thank you.

Wow thanks Franco.. superb info on newer versions Bluetooth.. 🤟🏼❤️from India 🇮🇳

Very cool info, thanks for explaining this.

Awesome explanation and easy to visualise the possibilities , hopefully 5.2 becomes quickly and cheaply introduced quickly so I might get it built into Bluetooth earbuds I'm looking into buying soon.

Very interesting! I have one question: if I got that right, with 5.2 one source can connect to many headphones at the same time. Does this also work if the source has 5.2 but one or more connecting headphones only have an older version?

I was scrolling through your videos and this one caught my attention.

Super helpful. Thanks

For dual audio, is it necessary that the receiver (speaker/headphone) also have bluetooth 5.0?

So nice explanation. Thanks! 👍

Im still trying to figure out if i can have 5.2low latency on wireless buds while using a 5.1phone... any help?

So im a video editor, depending solely on wired connections...but always open to bluetooth if latency issues are fixed. Does the new compression rate of this codec mean that the faster decompression fixes more of that latency issue I experience while editing?

That was a very good overview. I listened to it using AURACAST! I have 8 VOCE transceivers, and have one set up as a transmitter on my iMac. Another is plugged into my Bose 700 headset, and yes, I am wearing my Phonak hearing aids under the Bose 700. I can hardly wait to get Auracast for my Phonak hearing aids!

Thanks for the detailed explanation

will Bluetooth 5.2 be able to automatically switch between paired devices whenever you play media (per device)?

I have a Google pixel 2 and can't do that dual stero audio like Samsung can. I also noticed when I use Bluetooth in my Google home mini 2 there is a huge audio delay even though google makes the phone and home mini 2...BUT my Alexa speaker has no delay at all.

thank you, very useful information

Thanks for this video bro. I want to aske that is okay if u buy an test with 5.0 ?? Please help I'm so confused 😅

Thanks for heads up, to keep in mind when buying new Bluetooth gadget/device. 👍🏼

Does anyone know if 5.2 will make high quality audio+mic on windows possible? I'm stuck with hands free protocol which SUCKS

Thanks for your hard job on it!

bro is a version 5.2 wireless headset compatible with a bluetooth 5.0 phone?

I there a dependency in-between devices for 5.2 or the LC3 codec? E.g. if I have a smartphone which has 5.0 and don't have support for LC3 and have a TWS which sports 5.2 and have support for LC3. Do I get improved quality and fidelity?

Thanks man , great job!!!

Can't wait. I just want to listen to an audiobook with my friend while on a bike ride.

I am considering buying an iPhone 14 since it's the first iphone with bluetooth 5.3 (13 was still on 5.0!). Does anyone have experience with using ISOC with multiple streaming sources and a single pair of headphones?

Is Bluetooth 5.2 tws sound quality is more better ?

Will a Bluetooth 5.1 earbuds device work correctly on Bluetooth 4.0 android phone?

Very informative and easily understood when using a layman's term. I give it a 5*.

I enjoy listening to high-resolution digital audio music, namely, 192 or 96/24. I have always used wired headphones. Now all the good headphones seem to be wireless. Is Bluetooth 5.2 capable of handling such high resolution, or does it degrade the source? Thank you very much.

Can you also talk about 5.3?

Best video on this subject thanks

If I buy 5.2 headphones but all my sources are 5.0 (like iphone, PC, etc.) can I still take advantage of the ISOC feature of 5.2 or do all my sources need to be 5.2 as well?

Great Video

Thank you for this video

any expected date when hearing aid industry will adopt bluetooth 5.2

Do radiation harmful effects become worse with each version (due to increase of range) or least harmful? Sorry, just wondering as sometimes I've been experiencing headaches with speakers that suppry bluetooth 5.0 like anker soundcore motion plus and Boom.

Which smartphone has bt 5.2 ?

When will Bluetooth get Surround Sound or Dolby Atmos capability.This could be a game changer for computers and hand held devices?

Very helpful.

Thank you very informative I'm currently purchasing a new laptop with add ons.

Why dont most of the new 5.2 earbuds implement multipoint pairing :-(

Are you guys no longer making videos?

Nice to know such detail level. Also nice to say that there’s no iPhone with Bluetooth level beyound 5, except ip14…

My desktop has Bluetooth 5.0 & my previous phone had 4.1. Streaming between these devices had very very low range & up to 10 seconds or more in delay & not the best audio quality. I recently bought a new phone(not just for the bluetooth, a new phone was really needed) & my primary requirement was for it to be 5.2 just because of the capabailities it brings. Now I can easily walk into my kitchen with a somewhat connection, but no delay at all in the stream despite a poor connection. I'll probably buy a bluetooth 5.2 usb adapter & can only imagine I would have absolutely no problem with my connection from anywhere in my apartment to possibly right out to the garbage bin. I use wireless connection for all kinds of things & especially audio, and just upgrading my phone was already a game changer.

Thank you! Thank you! Thanks

I will wait for the BT-6 Super Deluxe Ultra X1

Is the .2 only about audio?

Great video I am very happy with WiFi 6E+BT 5.2 card worth the upgrade

Valuable info

Good summary. What we really need is ability to have Stereo Sound Quality + Voice Channel. Not the Mono shit it fallbacks to in Headset mode...

quick question, can i use BT 5.2 earbuds on a BT 5.0 Phone?

Thanks bro..

this is no "small" upgrade as far as control freaks out there, more efficiency the better

All these features are for convenience. For sound and audiophiles, there is no comparison to wired. BT still need to compress the files and can't even transmit basic CD quality sound.

Which is better for phone call no delay?5.1 or 5.2?

Please, Update this video

Not many options in 5.2 earbuds at the moment unfortunately. A lot of 5.2 earbuds are just AirPod clones, nothing compact or discrete looking. I really don’t like the AirPod stem look. Hopefully more diverse 5.2 earbud options come out in the future

Thank u

Very nice 👍

Thank you very much! Two questions: 1- Can dual audio transmit to two speakers in stereo mode (so that both speaker BT devices work in stereo between each other)? 2- Is the LC3 compression codec a lossless (100% of information retained), or lossy compression? After searching a bit and testing with gear I've recently acquired... I still wonder when the BT org will actually put their efforts into getting a higher bit rate for a better sound! LC3 will succeed in sounding better than SBC (old codec from BT 2.0 or 2.1), since it maxes out at 248Kbps for input files. 3rd party LDAC and aptX’s top codecs all work around 24-bit 44.1kHz, but still use what's known as "BT Classic": same rates since BT 2.1, but pushing the bit-rate beyond the standard SBC or AAC by hijacking other non-audio bits for extra data. BT LE would be good for getting lower bit-rate voice transmission, but it doesn't improve on the Hi-Res Audio side (raising the max bit-rate doesn't seem to be important for the BT org). Those heqadphones I've tried tant "accidently" jumped to LE, but then they sound bad. The "improved" version of BT LE doesn't improve anything in that sense (only better power consumption and simultaneuos streaming to multiple devices). Fraunhofer, the creator of both LC3 and MP3 codecs, also has an 'LC3plus' codec which goes up to 24-bit/192kHz. However, its specs indicate that 24/96 signals would not fit within the practical 1Mbps available even to BT Classic. So LC3plus seems more for streaming music from the web to your device, rather than from your device to your headphones.

Thanks, Eric Andre

You should have mentioned that the benefits of bluetooth 5.2 is only possible if paired with another bluetooth 5.2 device. You're not really getting the full experience if you connect lets say a 5.2 headphones to a 5.1 device. Dunno if they're gonna address that though. 🤷🏻‍♂️

Jake Peralta schooling me on tech! 99!

turn mic to corner of mouth less pops..

I bought a cheap Xiaomi Phone with 5.0 Bluetooth to be able to use Dual Audio. But for Sume reason it was not aviable despite it has Bluetooth 5.0.... Now im pretty sure Dual Audio its only a Samsung Feature...

The future is amazing

Waiting for Airpods Pro 2

*My earphone is under warranty and my earphone model is discontinued.* One side earpiece is sounding low. If it doesn't gets repair I'll get a better model as replacement. So how do I damage my earphone further so that I get a new replacement and warranty doesn't get breached.

The thumbs down must have come from a very angry & vengeful ex girlfriend! Awesome video concise, informative and definitely presented in a comprehensible manner For the lay person. Not a single wasted sentence! Thanks for the info Franco.

The Bose QC 45 have Bluetooth 5.2 :) So it will be great !!!!

What's next after Bluetooth 5.2 ?

Voila!

is the channel dead?

It's bluetooth 5.2 le not bluetooth 5.2 classic

You forgot about the super low latency in 5.2 for audio. Important for audio production.

So could bluetooth ever be lossless audio.

*SLAMS TABLE* GIVE ME LOW LATENCY BLUETOOTH WITH PROPER MCIROPHONE SUPPORT it's 2021 it's embarrassing. specially without headphone jacks... everything has advanced so much expect wireless audio. wish the tech they use in wireless gaming headphones would be standardized for phones and PCs and laptops. or that they AT least sold the modules separately from the headsets. does this mean there'll be less latency? finally? or am I hoping for nothing.

Its not gonna do shit for high quality audio, lossless audio is something like 1.5megabytes per second.

TV BUYERS BEWARE, Just purchased a 2022 SAMSUNG OLED TV expecting my 5.2 ANC TWS earbuds to be copasetic with the new TV Bluetooth audio interface….NOT!!!! 😡 Terrible latency and iffy pairing issues abound. Turns out Samsung is still using the archaic 4.2 BT chip in all of their new sets! So I checked out the new LG TVs and discovered they are the ONLY TV manufacturer now using the relatively recent BT 5.0 chip and I had no issues with good pairing and low latency with my buds….SAMSUNG on the return docket.

I play music. I want 1-2 ms of delay - NO MORE....

😢i have bt 5.4

plosives festival

too much hype, no real testing to see the numbers around latency, speed transfers, quality around the new format... You can literally encode something into a new format and do a comparison with the original audio to see how much if anything is lost during the compression.

Slow down please.

all i care about is audio quality and range, or others are useless info..

Good. But 5.3 is here now.
