Review: Get this over the regular AZ09 - The noise floor is hardly noticeable and I haven't experienced any connection issues in the past month compared to the original AZ09. It uses regular aptX not aptX adaptive but the sound quality is still solid. It's not listed in the manual but triple-clicking the left button enables a hidden high-gain mode that simply makes it louder. They also have a quirk where sometimes they will stay on and connected to my phone inside the case but just making sure they are seated properly on the charging pins has prevented that from happening again. Battery life is amazing compared to regular TWS earbuds. I use these continuously for 5-6 hours and my phone still shows 50% battery remaining. Unsure if that is correct but that's already more than the 4 hours I get with OnePlus Buds Pros with ANC on. I paired these with my Moondrop Arias but they will need modification since these are C-pin and the B-pin version is nowhere to be seen. The black part is silicone and the inner part is plastic so it is very easy to trim with a knife and file.
Review: Needs adapter for recessed 0.78 IEMs, but works well! - Disclaimer: I’m using this with an adapter so they are compatible with the Simgot EW300, which originally has a recessed 0.78 2-pin and will not work with the AZ09 without it. Sound quality is better than I expected for the cost of these Bluetooth adapters. I use them exclusively in “full power mode” which is accessible by pressing the button on the left side three times. It doesn’t seem to just be a higher gain mode, since it sounds noticeably more open and less muffled once activated. Not sure if this has an impact on battery life. Compared to wired, I feel that the slight loss in sound quality is an acceptable trade off for the convenience of wireless. I reduced it by 1 star due to the cheap construction of the case. The lid feels thin and flimsy. Does not inspire much confidence in durability but if you take care of it, it’ll be fine. Just don’t drop it! And one last thing to note: I tried the AZ09 initially with the KZ EDX (no adapter needed) and there was a noticeable hiss both when nothing was playing and in the background when music was playing. Oddly enough, that hiss went away when I switched them to the EW300. I’m not sure whether to blame the IEMs or the AZ09.

A: Si, pero debes comprar la versión con pin c

**Q: what ipx rating are these?**

### ⭐⭐⭐⭐⭐ TWS for audiophiles!
*by J***S on August 2, 2023*

I have been looking and waiting for someone to develop a TWS for my good multi driver IEMs and KZ has delivered with the KZ-AZ09 Pro. It is also called the KZ-TWS HD Bluetooth upgrade ear-hook. It uses Bluetooth 5.2 with support for Apt-x formats as well as low latency. The two pin connectors work of course with most KZ IEMs but also with TRN such as my TRN ST5’s. My favorite pairing so far though are with the KZ ZAX 16 driver IEMs (pictured). I stream mainly through Amazon Music HD. These support up to 24 bit/48khz. The ZAX sound as good as any wired solution I have at the moment which is not saying a lot since I do not own anything that can play much higher than that wired. Performance wise, they drive the ZAX with ease and with good dynamics and details. People complain that the ZAX low end is not very good but I seriously beg to differ. With the proper sized tip and good seal the low end is deep, punchy and fast. No bloat in my opinion. The wireless connection has been very stable and has great range. Battery life is really all day with these. I did 8hrs with them straight and still had yet to get the low battery warning. The case charges them with a built in battery to charge them about 4 to 5 times before it needs a recharge. The case has a current usb-c connection for charging but does not support wireless charging. For the price of around $49 you get a great bang for your buck! Highly recommend!
