Review: KZ AZ09 vs TRN-BT3S vs KZ HD gray BT adapter for IEMs - After ordering 2 different sets of IEM BT cable adapters from KZ (TRN BT3S and KZ HD gray cable) and I picked up the AZ09 against some of the reviews and was pleasantly surprised that 1) finally my callers could hear me properly. 2) it connected very fast like the KZ HD but I could use just one ear if I wanted and 3) the case is slick, magnetically grabbing them into position and charging them on the go. The led indicator is helpful and these finally let me wear my glasses much easier than the other two which I had to constantly trap the wire underneath the legs so they wouldn’t fall off. The BT3S were not bad mic wise but its not BT5.2 and connection was so so. Cutting in and out with a snapping audio cut everytime was irritating and replacing iphone clicking sounds with these annoying loud beeps sucked. Latency was terrible as well, had to re-pair them quite a few times to get them to sync up again. The KZ HD set was a good one and I hesitated returning them but the one main flaw was the length and arrangement of the wire. If they update the BT3S with the guts of the KZHD and shorten the cables a bit they would have a winner. Alas whenever I would take off the left one it would drag the mic and buttons to the back of my neck and that SUCKED. As a listening set it sounded great. I might say maybe better than the AZ09 by a bit. Louder and cleaner. By 5-10% Overall I am very satisfied with these AZ09. Sounds close to wired sound and I have them paired with KZ ZAX Metals in black which sound fantastic on them. Little bit of noise floor but tolerable for a day to day device. But they win all around. Definitely recommend them.
Review: They Work Really Well, But. . . - I bought the AZ09 to pair up with my KZ ZAX and iPad Pro 11 (2nd Gen). The sounds was great, pairing was easy. After about 10 minutes the audio skipping started. Followed the standard instructions and removed the device, rebooted my iPad, re-paired and same thing happened. I than paired to my iPhone 11 and no audio skipping with a super stable connection. I than paired them to my iPad Pro 10.5 (1st Gen) and again no audio skipping, so I relegated the AZ09s to the closet never to be heard of again. However, I went on the internet to search out this issue on the iPad Pro 11 and it turns out that there is a bug with “hey Siri” enabled and audio skipping. Turned off “hey Siri” and problem solved. I am now finally enjoying the AZ09s full potential. They do produce a slightly warmer sound signature. Bass and mid-bass ranges will be slightly more pronounced, mids and highs still sound great paired with the KZ ZAX. You will also get a little bit of audio compression but the is the price of Bluetooth. There is a high performance mode that cuts the audio lag in half meant for gaming and works as advertised. Battery life is excellent with fast re-charge rate. If you are getting audio skip on you iOS device, disable “hey Siri” and try again!

### ⭐⭐⭐⭐ Useful add-on if you already own KZ IEMs, but don't go out of your way to get these.
*by I***N on December 3, 2021*

Have been using them a few days now and this what I think so far: Sound Quality: The sound quality with these on my KZ ZS10Pros is on par with what I'd expect from a decent sub-$100 set of True-Wireless headphones--which is to say, perfectly acceptable. Bass is a bit over-emphasized to my ear and the highs are almost too-crisp, like a sharpening filter or eq preset is being applied. To me it's perfectly usable for casual use, but if you listen critically you may well notice the compression artifacts, particularly in songs with wider dynamic range and in older remastered recordings where there is tape hiss. Honestly, if the ZS10Pros were not so dang accurate, I probably wouldn't have enough resolution to notice. Interface: If you come in knowing what to expect from cheap true-wireless setups, there are no surprises here. The buttons are clicky microswitches, one on each earpiece, with different commands delivered different numbers of clicks or holds. The "power on", "power off", etc. voice prompts are delivered in a comprehensible but almost cartoonishly heavy accent. No volume control, so you'll be relying on the device you pair to for that. No app support, no EQ. There is a "high performance" / low latency mode...I haven't had time to mess with that much. Battery life: Used for 2-3 hours a day at my desk at work for the last couple of days without charging the case and no problems so far. Range: At least as good, if not better, than other bluetooth headphones I've used. They make it to the coffee pot and back. Overall: I wouldn't buy these (plus a set of IEMs) as a standalone product, but if you already have KZ IEMs and want to get more use out of them in casual listening situations, the value proposition at this price is more than fair. I'm happy with them. I might have been happier had I waited for the AZ09 Pros (those apparently have a Qualcomm chip and AptX support) but anyway, there it is.
