Sir zpolt can you give thoughts about kz az09 vs kz hd aptx bluetooth cable upgrade
the 1st one that they sent me, the connection is not that stable when you wear the L&R adapter. The replacement that they sent is the same. You will be annoyed if you use it in a conversation
Zpolt is there any connection issues or any errors to the az09 after you've had them for a while? Mine just arrived and seeing if they'll eventually go bad or not.
Hello bro this very helpful review my question and required iam listen music + gaming on pubg mobile so iam accepte this is work on my field like pubg music and calling
And iam use kz bluetooth wired upgrade cable this is so nice sound quality and + latency is best
but
cons is
Wired quality is very very duffer and bad so and one design is good but is all the time sleeps my ear and iam use only one year is and his and this time kz on my dustbin because his wired cracked is joint sided iam disappeared and dissapointed purchase on kz bluetooth module wired so this time iam check the all side of pros and cons
Tip: tap the button 3 times to activate high performance mode to listen high quality audio. been using this for a month now and i must say its the same quality using wired, im pairing it with my kz zsn pro. it last about 8hrs straight and the box can charge 2-3 times which make it last about 20-24 hrs of usage
nice info.
i want to pair it wiht the kz zs10 would that be good for gaming?
does the box serve as a powerbank that charges the earphones wirelessly?
@@kekekw3478 Yes. The case is a charging dock
@@figoamigo2692 maybe not amazing for gaming due to the latency but otherwise i would imagine them being fine
10:59 I love how you added this bit. Something practical that others might overlook, but a very good thing to consider as well. :D
Aaaahhhh yeeeeeeeees! Been waiting for these!
Had this bought with my first IEM KZ DQ6 and they amazed my weeks
Great review! Thanks for sharing your considerable knowledge, friend. Cheers!
KZ finally done it
Although I guess this module is similar to KZE10, the first TWS from KZ
They're good, but I think KZ is still Experimenting... Hopefully we'll get a better "Pro" version soon
Woaahh finally💯🔥
Thank you for the review! I was planning to buy one then I heard that they have released a KZ AZ09 Pro. I'm gonna wait for that review, in the meantime, keep it up and thanks to you I was able to choose which IEM I want as well!
NOOOO 😭 I JUST GOT THE NORMAL AZ09
Looks like a solid tws adapter. I will probably wait for one with LDAC support
finally, I've been waiting for this
same!
I'm still waiting for a version with aptX and volume control..
Good enough for iphone
Hoping to see the KZ AST review soon😄
I bought these as soon as they were announced. I loved the sound, but quickly had connection issues . KZ sent me an "updated" version, and it's been smooth sailing ever since. What a value!
What about the noise floor? Is there any hissing sound while not playing anything?
@@shaswatdas6553 you can only hear the hissing when u stop the music and it will just last for about 2-3 sec
They should have added aptx instead of hard case & packaging. Hope they add aptx for future versions.
Finally have been waiting for your particular review...
I think i am gonna buy it in 1 week for my Kz Zsn Pro since It's Wire is destroyed
i know this comment is 2 years old, but how are they holding up?
Kz read my mind. Good job kz👍
Im waiting for this .
Nice review 😀👍
I was waiting for these products to get cheaper/prettier compared to when TWS becomes the trend.
Great and relevant review. I'm gonna add this to my cart now
That is really usefull because my iem's are kz's and the only wireless earbuds I have are some cheap wireless ones from amazon (bought just for casual and out and about listening but kz's are better for that I realised) but they have issues and I really like my kz's
They could save me plenty of money.
Thx for the review and you earnt a sub.
Hi! How's the sound quality compared to the "older" KZ bluetooth adapters?
Also, any comparison regarding the sound quality of iem+KZ AZ09 vs other KZ tws like the Z3, S2, etc?
Hey man thanks for this review! One question, when you did the latency test, was it with High Performance mode turned on?
I connect mine to my KZ ZAX and its really great. Highly recomended
Good news, type B pins have appeared and will support some of your IEMs.
Wow! I was wondering when, but now you actually review this. I'm so glad how bang for the buck this is.
This actually has a gaming/high performance mode, just click the button 3x.
What difference does the high performance mode make?
Thank you for the information. So far I have been disturbed because when I listen to music on CZcams, the tone often sounds up and down. It turns out that with this mode everything is normal. I just found out after using this for 3 months. LOL
I bought these as a quick replacement to my UTWS3 and my wife (somehow) lost one of them. So that I could use them will other .78 iems besides the KZeds I modded them by cutting off the plastic surrounding the 2 contact prongs. Work great on all my compatible IEMs now.
so what do you think compared to utws3, i’m confused to choose between those two
waiting ur az09 pro review😈
Nice review Zpolt!. Have ordered. Will the KZ ZSX fit in the box?. TRN doesn't accommodate them.
I bought the QKZ-VK4 after watching your mic test on a bunch of EIM... thanks for that because I'm very happy.
Now, this adapters...can be use for any EIMs? I will subscribe and wait for your review when you get one adapter with aptx codec and Qualcomm chip..
Hello I've been researching bluetooth adapters for the KZ ZSN Pro X that I will be buying but the options out there are really janky I wanted this kind of adapter but the bad reviews on this product and as well as other bluetooth adapters are really high that I feel like I'm just gonna be wasting my money.
So I've looked at bluetooth receivers and ther are really expensive and over my budget. I did found one in Lazada that's quite cheap the
Ugreen Bluetooth 5.0 receiver for php800. Was wondering if anyone had any experience with this and what's it like. Thank you.
I have those and a pair of zax and one of dq6 and I noticed that with the zax I was loosing a lot of high end and clarity and the bass sounded boosted and unnatural, so I wasn't able to use them with the zax, the dq6 was different because the sharper v spectrum was balancing the loss of high frequencies and the sound experience was better. I would suggest to use them with less analitical items, these are still my opinions and I am not an expert whatsoever so take these with a grain of salt. Quality over price 10/10 still
Tap 3 times for high performance mode
like your description
the case makes it better than the other Bluetooth adapters
I already have mine haha I saw a brazilian reviewer talking about this one and bought for my ZS10 Pro. I really loved it!
How is the battery life?
Same setup bro heheehe..
how is it now bro?
Can you give an update please
please review the kz zex. thanks dor this review.
I initially purchased the AZ09 Pro. I was sattisfied with the sound quality etc... I decided to get the AZ09 as a second pair for working out and treating it without much care...
I don't know how other options in the same price range fair, however the AZ09 have a very high noise floor for my taste... I like to listen to music in medium volumes. I also like songs that have dramatic pauses... Listening to a constant hiss is NOT ideal.
I got the AZ09 for around 18€. The AZ09 Pro costed 36€. Were they worth it? IMHO yes. They have 5-6 times less noise (what I can notice at least), that's close to no noise, much better battery life and are arguably prettier. They have weirder sound effects tho...
Anyways, if quality is your priority (since you are looking into these options, I'm guessing it is), skip the AZ09 and please go for the AZ09 Pro.
All in all this noise problem is a little stupid... I have a Fiio BTR3 Bluetooth receiver. It has independent volume control for the bluetooth unit (not the volume of the device sending the audio). If the BTR3 is on full volume, it has some noise. Similar or just a tad higher than the AZ09 Pro. If I lower the volume of the BTR3 the noise reduces accordingly. When at 50% volume, there is no noise at all. Much better than even the AZ09 Pro.
So why doesn't KZ give us the option to lower the output of the unit? Why does the noise remain the same even when in high performance mode? Is it possible to have such control through software (an app on our phone that intructs the unit to reduce the output)? Maybe... But we'll never get these things, because the AZ09 is a cheap unit :)
It might be easy or it mught be hard for these things to be done. What's certain is that it's better for sales if the AZ09 Pro has such a lower noise floor.
Now I just thin to myself... What is the noise floor of other similarly priced options... If anyone is kind enough to reply...
Im planning to buy kz zs10 pro x with kz az09 pro. But wanted to know wich one is better. These pair? Or soundpeats capsule 3 pro?
Im still using the stock cable that came with the KZ ZSN as the jack is kinda broken now and I was planning to buy either the old Bluetooth adapter and the Type-C cable but the the latter seems it is phased out now(at least in Lazada or Shopee) until I found out the AZ09. Is there any difference in sound quality if I upgrade to the AZ09?
Interesting. Thanks for sharing your review. I wonder about durability- Any accident drops from ear height and still worked?
I have Blon BL03 thinking to try this.
Someone knows if the az09 are sweatproof? i´ve seen the pros are sweatproof, but there are some descriptions in amazon that say the regular model is also waterproof, but nothing from a manual or official kz page
Watching this review, with my KZ AZ09 + DQ6, d ko na naantay ung review mo haha
i've tried using this while playing valorant/csgo, ok nman latency, bsta naka-on ung high performance mode
Do you recommend it?
I hope you get to review the newest KZ AZ09 pro too.
This, is, really cool😎😎, very 👍👍Nice
Good, one👏👏✌🙂
Bought one of these. was really good, unfortunately battery charging failed on me for the left earphone after a week.
KZ SKS review next please 🙏🏻🙏🏻🙏🏻
Derrick, would the case fit when it plugged into CIEM ?
Sir zpolt can you give thoughts about kz az09 vs kz hd aptx bluetooth cable upgrade
This is very similar to the design I was thinking for a TWS adapter for chifi iems. Just need to add aptx
Hi everyone! My case's lid closes down just by gravity. Is it too loose? It's brand new but idk why this happens.
Hi Zpolt! Can a KZ EDX fit on this KZ AZ09? I'm not an expert with the kind of stuff.
I have the aptx Bluetooth cable thingy how does it compare too that I don't like the fit of that one it pushes my ear piece out of my ear constantly but I'm fine with the sound so how does it compare too that one
how does this fare when paired with Moondrop Aria / Aria Snow? I ordered an Aria snow and wanted to convert it to wireless but do not know which one to buy.
Perfect. Im using Kz Zsn for 2yrs.
Thinking of upgrading to Zsn Pro X or this
You should! The sound signature of the ZSN changed and is much better than a couple years ago. Also, the ZSN pros are a great grab for only a few $ more.
There are new GK GS10’s on amazon that have 10 drivers as well, sound similar to ZS10 pros but half the price.
Same here. I've been using mine for over 2years and its still good as new.
Will this works with other brand iem? Like moondrop starfield or aria?
Hi, hope you can review Baseus Simu S1 ANC. Thanks! 😉
High performance mode decreases the latency Incase you are gaming so your gaming audio is not delayed. Change your Bluetooth codec from sbc to aac. Aac has a better data transmission rate and sounds better. Should have no complications. Overall this product is on par with kz products it works fantastic for the cheap price they ask. It has more like 8 full charges on board and sound quality is good if close to the device. I use mine with a pair of KZ ZAX. I recommend the product for these IEMs atleast. Overall a solid products it's kinda quiet in sbc mode but in aac Bluetooth codec the volume is so loud I use about half volume typically.
hey, how is the latency for gaming? is it at all noticeable? and did you try it on android as well?
Also, does the aac option not show up in the bluetooth settings? and does it have better latency? I thought AAC ony had better quality. please let me know if you can, would be much appreciated, thanks.
@@EpicBunty I only use it on Android. I typically use one a time because they're a good option when I'm around my wife. I wouldn't say I've noticed any sort of delay or latency issues. I cannot really even tell the difference between 80ms normal mode and 40ms high performance mode. I have not really used them for gaming but my KZ ZAX 8 driver IEMS are phenomenal for sound quality so I would imagine they'll be alright. If I am gaming I use fully wired HIFIMAN HE-X4 planar dynamic headphones as there is no latency and the audio is more naturally. Regardless for only $30 you can't go wrong. You'd have a very hard time finding anything even on par with the AZ09 for the price range. If you want no latency gaming get a 3.5mm wired set unless wireless is important for you. Like I said 40ms is hardly any delay and you would probably only ever experience issue if online and I doubt you would even then. Worth the money. As for swapping to AAC I can do it in my Bluetooth settings for the AZ09. My old phone I had to go into developer options and change the Bluetooth codec that way.
Can you check if the wireless module has built-in in mic ??? cause I tried and it seems like jlno audio coming out
to improve mic performance i use one in ear and second in hand in front of my mouth like a lapel pin during a call
Just ordered this via Lazada flagship shop! Btw can you do a difference between KZ Z1 vs KZ Z1 Pro? It's really bugging me because the Z1 is much pricey than the pro.
For BLON BL03 users, you can cut off the acrylic surrounding the connector so you can use it with the BL03. For IEMs with recessed ports though you can't use this.
It's true!!! But U can't use in other cable
File the corners round with a smooth finger nail file.
@@kakanic sure. Like how you can't use qdc with some 2 pin or 2 pin with mmcx. This is just a tip to be able to use this with BL03.
Hello, I have 2 of them and when I connect them to a cell phone, they both pair to the same cell phone, can they be identified separately when connecting them to a system? Thanks
I've been hoping that you'd finally find a TWS adapter worth getting. Thanks!! I've ordered one on Amazon today.
Do you recommend it?
@@Rorensuwl8 Yes. I am using them with a set of BA5. But they aren't perfect. Volume is LOUD. I needed to turn my volume down to 10-15%. I do get a random drop out infrequently. But I am still happy with the purchase. They work better than any other TWS that I tried and I get to choose my IEMs.
@@kato258having the same issue with the volume. Have you found any tips with how loud it is?
It seems I received faulty unit of these. Left side ear hook doesn't turn ON. Any idea mate?
Which is a better buy? A bluetooth dac or a bluetooth cable adapter (kz aptx hd or the ones in the vid)?
Bro you made me vibe with just 14 seconds! (acutally 7 cuz I was watching in x2 lmao)
Just want to ask of this KZ AZ09 is compatible to other brands with 2 pin connector?
Hope you can answer this querry
Bought QKZ VK4 due to watching your videos.. and bluetooth/wireless are greath for online this days
was it really rated sweat resistant? mine didnt last regards the home work out and hourly calisthenic, sweat seems to ruin the copper charging contact of the adapters. opened it and learned the parts are badly soldered lightly regards its scale.
Thank you...
Can this be pair with tfz live 1 ?
Love mine but.. the LED on the case doesn’t work on mine 😢
hi .. This model can fit with Opera factory Om1?
Is there a sort of teardown in sound quality with az09 vs direct wire conn?
Hi. Can they be used with CCA CSN and which pin to select. B pin or C pin
Does it work for other brand of IEM like the RM-833?
I hope they could make an anc one. They would be good.
💯💯💯
I’m late to the party but I just got it yesterday for my zs10 and it’s very good for the price
I was wondering if you can use these with the Blon 03
Will this fit other IEMs? I have the moondrop CHU and this mic has the other version of the 2 pin that looks like it'll fit the CHUs
mine is sometimes failing, losing connection. yours too?
Hi guys! any of you had an issue where the "Right BT Adapter" is connecting even syncing to the L BT Adapter? Also, there is this dim Red light that frequently appears and will not turn the "Right BT Adapter"... I have tried Resseting Both Adapters and will still not connect. I also tried to connect only the Right Adapter but AZ09 will not show on the Available Bluetooth Devices lists on any Phone. I hope someone was able to fix this.
Hi, can you help me? I'm having problem on the Mic, I only hear buzzing Sound when listening on what the mic is receiving and it's connected to PC via BT dongle. How do I fix it or what do I need to do?
How long does it take to fully charge the ear hooks from the case? And how do you know that the dead ear hooks are now fully charged from the case?
hey i have a question? they do not sync both pairs my phone only get one pair to sync it's either left or right not both? how's that badly need an answer because in my experience of using it no problem then after long usage I encountered that problem that they cannot work both pairs in my phone
Hello can I just use one independently without depleting the battery of the other
Does it also charge the iem earphones inside the az09 case?
Can it be paired with Bluetooth transmitter? I'm planning to use this with airplane entrainment system that only have 3.5mm output and replace it with 3.5mm to Bluetooth adapter from ugreen. Thanks
Does anyone unit have a terrible noise floor, hiss when no audio is playing? (using with zs10 pro)
Can i use this adapter with moondrop ssp?
I bought mine recently, Nice review man, can you make a video on what IEM is best to pair with those? Thankss Man
He said that the adapter is noisy, so you want something less sensitive to hide the noise floor.
do you still have it? how is it now
Hey, can this be used with starfield moondrop?
Could I use this adapter on a pair of jade audio ea3?
Theres a pro model with aptx now, are you going to review it?
Can this be used with KZ ZS10 B-type pin ? If not any suggestion ?
What charger can i use for my kz-az09? Is it okay to charge the charging case while the iem is inside?
Really need a comparison for fiio utws5 and kz az09 pro..
had some issues with it idk if it's just not in high-performance mode but there are some pops here and there and there are times when the left side pops and disconnects
Hello friend
What is the best kz AZ09 or trn bt3s cable I mean sound quality ??
I'm planning to buy this kinda soon because I've bought like two or three sets of IEMs and two of them had broken earbuds and I use their wires as spares for my third one, but now, all of my wires have one side broken. I've bought KZ EDX Pro before and also bought QKZ AK6 and their wires still work if I pair them to each other's wires.
But in this case, does this work on other IEMs from other brands (like QKZ AK6) or does this only work with products from KZ? I don't want to spend 20+ dollars for it only for me to still need to buy another KZ IEM. I hope someone can answer my question.
Could this pair nicely with the Arias?
I have seen some adapters that say they play with the ldac codec, that is true?
