Review on 🎧 KZ AZ09 Bluetooth 5.2 IPV5 Waterproof Noise Reduction Module Upgrade Cable Ear Hook for ZSX/ZSN/ZSNPRO/ZSNProX/ZS10PRO/AS12/AS16/ZAX/DQ6(C pin) - Enhanced SEO by David Jones

I installed my KZ DQ6 iem and connected to my phone within seconds. Very stable, no dripping. The range seems to be on par with the advert, around 30 feet. The sound is great! I cannot distinguish Bluetooth AZ09 from a wired connection. Bass, mids, highs... it's all there. The volume is more than sufficient, you can turn it up if you want. The latency is very good, I tested the "High Performance" mode with Netflix. I didn't notice any lags with the picture. The battery is good, about 7-8 hours on the first charge and use. I haven't had time to check how many charges I can get out of the case yet. The quality of the pods is good, they are very well assembled. The buttons are a bit small for my fingers, but the actuation is very positive. The charging case, on the other hand, is "plastic” but strong enough to easily fit in my pocket. The charging port is USB C, which is a plus. Overall the quality is very high for the price. I can't rate the durability yet as I've had the capsules for less than a day. But based on my previous experience with the KZ brand, they last a long time if you take good care of them. Overall I think the KZ AZ09 bluetooth adapter is a great product. I highly recommend it!
