Too Many Issues - Update
So far so good. Set up and connection were clearly described and went off without a hitch. These are much lighter and looser fitting than my TRN BT20S. I've paired them with my KZ ZAX, and they sound amazing! Very pleased with this purchase so far, and for the asking price it's a no-brainer. UPDATE: Seemed to work fine at first, but after about a week of use they are constantly and frustratingly cutting out. These have become unreliable and ultimately unwearable. :( SECOND UPDATE: Seller offered to replace with a new version. So far connection is flawless and all is good! ... show more

I really really wanted to love these
I've been pretty stubborn when it comes to trying out wireless headphones and earbuds, constantly preferring to buy phones with headphone jacks and always sticking with wired because I really never saw the cable as that inconvenient. And I've pretty steadily using KZ ZSN Pro's for the past year and a half, being some of the best value I've gotten from headphones to date. So when I discovered that there was an official bluetooth accessory for it at a reasonable price, I had to try them out. Well I'll start with the good: The packaging and build quality - As with the ZSN Pros, the packaging and overall build is phenomenal for the price you pay. I've had worse presentation from earbuds costing 4x as much as these things, and just the general feel of the actual case in the hand is nice. It's obviously a bit bulky, but it'd be a bit much to ask for Airpod like footprint from something this cheap. The magnetic hinge is a bit slippery for my tastes but works perfectly fine. Also glad to see Type-C charging and an included cable (albeit a comically short one but points for including one at all). The look - I absolutely love how these things look. Integrating the original braided cable design from the ZSN Pros with the small bluetooth receivers. I appreciate them not going with the usual long flat cable design that so many cheaper wireless earbuds do and making them look even more expensive. The case itself also looks as premium as something far more expensive (even if it doesn't feel quite as nice as it looks). Sound quality - This shouldn't be much surprise if you're familiar with the original IEMs, but they sound just as great when they work (not to bury the lede here). They sound maybe just a *tad* worse than if you use them wired, but it's such a minute difference I wouldn't notice if I wasn't looking for it. I've seen some people complain about increased static (something the original ZSN's struggled with), and it was maybe also a *tad* louder but if you're used to it on the wired version you'll be fine. And honestly, I didn't notice a difference really between the high performance and normal modes, although that might be down to my limited testing and not trying any lossless audio with them. The average to bad but inconsequential: Initial setup - I found it a bit clunky at first, because only one would pair at first (seemingly because there was supposed to be tape over the contacts keeping them from connecting without removal but one wasn't even int he correct spot) and it's not exactly intuitive if you haven't checked the manual beforehand, but it could definitely be worse. And chances are you won't be doing this much either way so whatever. The built in voice - There's a voice that comes on and tells you when a function has been done such as "disconnected" or "pairing". Normally this would hardly be worth talking about, but the AZ09's is so atrocious I can't help but mention it. It's rather inconsequential which is why I put it here, but they're using a text to speech thing very clearly not meant for English, as it manages to pronounce "disconnected" like "dis-cone-neck-tate" with a very odd accent. It's still usable, but it was an odd choice to not just use a voice designed for the language of whatever market they're releasing it in. And the bad: Staying connected - If there's one thing I can hope bluetooth headphones don't screw up, it's managing to stay connected to my phone while I'm listening to music. You know, the basic thing they're designed to do. But these don't manage to do that. For context, I decided to take these working out one day to test them out. My phone is no more than a foot or a foot and ahalf from my ears most of the time, sitting on a machine. I don't even end up moving my head much while using them period. But over the course of about and hour and a half, these were near unusable. I could not listen to a single piece of music without the left and right ears dropping out constantly, almost independently of each other. I switched to high performance mode hoping this would fix it, but found no respite from the godawful experience of using them. I kept hoping they would get better, but nothing changed over the course of my workout. In fact, I could swear they got even more flaky as time went on. They were at 100% battery as well, so I have zero reason to believe this was tied into my dropouts. I later tried them at home, literally sitting completely still at my desk and found the same exact experience as before. Overall, I just cannot recommend these when they can't even do something as simple as stay connected and transmit audio for more than 5 seconds without dropping out. I expected better from KZ, I really did, and I hope they can manage to release a new iteration that fixed this issue. But for now, I refunded my order and I'm sticking with my wired ZSN Pro's for the foreseeable future. ... show more

AZ09 True Wireless Adaptor is awesome

I took the plunge even though I’m normally reticent of ordering straight from China, alas, Amazon only left me with that option. It took about three weeks for them to arrive and they are as advertised (except the buttons are different looking than on the website, but I think they blend in better so I don’t care. I’m using KZ ZS10 Pros with them, and the connector is the same C-Type so they hold firmly. They definitely aren’t as loud as using the APEKX Clip Bluetooth receiver I’m accustomed to with the factory cable, but they’re about as strong as using the Apple lighting dongle to connect to my iPhone. They seem to have no problem remembering three devices (Apple TV, iPhone and iPad), but they automatically reconnect to the previous one so you have to manually select them on a new device (and sometimes disconnect them from a previous device). The case is about double the size of the AirPods Pro case and twice as thick, but does charge them from about 20% to full in 30-45min. They have a “high-performance/low-latency mode” selectable which I assume must be for gaming. In standard mode I have no issues with audio sync to watch movies. The range is about normal for Bluetooth, 10m (30ft) ish, and if they do disconnect they reaquire the last device once you’re back in range. Putting them in or removing them from the case powers them off and on after the first pairing. It’s also important to note the left side is the master so you have to pair it in order for the right to then catch up. If you pair the right side first you’ll never get the left to pair. Once they’re paired, however, you can use them one side at a time if you wish. I’ve only placed a couple of calls with them from my apartment but neither party seemed to have any trouble hearing me and I didn’t mention I was using new wireless tech. The battery lasts over 4.5 hours of continuous use (they advertise 6-8 and I can believe it) and I haven’t managed to need to charge the case again after three days with it. ... show more

Wasn't Expecting much for the price but I think we got something!
Review Image by Michelle Geer Michelle Geer
Just received them today and sounds really good for the price! Doesn't get LOUD but more than adequate for my needs. If I want to get more serious with my music I'll just go for hard wire. Didn't bought these to replace hard wire. Just to use them at work. The reason for 4 stars is that It didn't fit the KZ ZSN Pro very good. It was too tight and didn't cover the entire base of the pin connector. I also own the KZ DQ6 and had better results. So to get around that issue with the ZSN Pro, I did a self mod. I cut the plastic ring around the pins with cutting pliers or a nail nipper. I slowly cut it until I hit the base where the pins end and then I just clean it up a bit. Get rid of the plastic shaving. Now with the mod, I can use my other 2 pin IEMS! In the picture above I have the FIIO FD1 connected with the KZAZ09. ... show more

Try something else.
They worked perfectly for a few weeks. Now they just kind of do whatever they want. They randomly turn off, turn on, connect, and disconnect. Sometimes they won't connect and they have be wiped from the phone's Bluetooth memory. The connection has started stuttering recently as well, even with the phone 6 inches from the ear piece. And the Engrish. Holy cow the Engrish is so so bad, the notifications only just barely sound like the word they are supposed to. "Connected" is "con-neck-tate." At 10% battery it's starts saying "lo-bab-tree" every 23 seconds. And it does this for at least 16 minutes. It is absolutely infuriating. ... show more
