Review: Great bluetooth headphone adapters! HD Audio latency is kind of bad, but you can fix that. - I'll give you a quick TLDR: They are good, buy them. They have latency on HD audio which sucks for watching video, but if you turn of HD audio they still sound great and the latency goes away. The rest of this is specifics about the the audio. Honestly, these sound amazing and I don't really feel the lack of lossless audio. The AAC audio is very high definition and it doesn't really sound different than one of my bluetooth DACs with lossless paired with the same iems. It seems that the digital amplification circuitry is very good a similar to a proper dac. No "hiss" at low audio levels and no crunchy fade in's from silence to audio. Reading some of the other reviews people have mentioned that the pairing audio is super loud. I would agree with that, but in my case I never ran into disconnections so I never deal with it. I think if you also experience solid connectivity that shouldn't be a problem, but your success will vary. I will say that I am really please with how stable the connection is as a huge guy. This is going to sound dumb, but I'm used to headphones cutting out if they don't have really good bluetooth because bluetooth signal has a hard time transmitting through flesh. Being 6'5 and 350lbs, I'd say 1 out of 4 bluetooth headphones I use cut out randomly at times because of this issue. These didn't have that issue with either headphone. One tip I will give people with these is that, if you are dealing with serious latency while using them to watch things like youtube, it seems like these headphones are slow on the decoding of the HD Audio. They sound genuinely fine even without HD audio on, so if you are using them with Youtube a lot you might turn off HD audio. Oh, and the case is 10/10. Seriously, I have a case for my IEM's and it's fairly compact, but given the nature of the IEM's I use the most, they are just chonky. It's hard to make anything that isn't thick that can safely store them. This has just enough room and the rounded edges makes it about comfortable as a case for these IEM's can be. It makes me want to 3d print a similar case, but with a little extra room for a cable. Review: Excellent! - Have turned my IEMs into amazing earphones. They connect well. Make sure that they've been disconnected from every other Bluetooth. A minor niggle is that they have very short range. Otherwise they're fantastic ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | CCA | | Colour | Black | | Ear placement | Over Ear | | Form factor | In Ear | | Headphone jack | 0.75mm Jack, 0.78mm Jack, Wireless (Bluetooth) | | Noise control | Sound Isolation | ## Product Details - **Brand:** CCA - **Colour:** Black - **Connectivity technology:** Wireless - **Ear placement:** Over Ear - **Form factor:** In Ear - **Headphone jack:** 0.75mm Jack, 0.78mm Jack, Wireless (Bluetooth) - **Included components:** Wireless Charging Case - **Model name:** KZ AZ09 - **Noise control:** Sound Isolation - **Wireless communication technology:** Bluetooth ## Images ![CCA KZ AZ09 IEM Bluetooth Adapter, Bluetooth 5.4 Module, Wireless Waterproof Ear Hook Extra, Long Battery Life Cable for ​KZ ZS10 PRO/X/2, ZSN Pro/X, AS16 PRO, Zax,ZAR, CRA/C12(C pin) - Image 1](https://m.media-amazon.com/images/I/51wxFWDmtiL.jpg) ![CCA KZ AZ09 IEM Bluetooth Adapter, Bluetooth 5.4 Module, Wireless Waterproof Ear Hook Extra, Long Battery Life Cable for ​KZ ZS10 PRO/X/2, ZSN Pro/X, AS16 PRO, Zax,ZAR, CRA/C12(C pin) - Image 2](https://m.media-amazon.com/images/I/51GE7jolXJL.jpg) ![CCA KZ AZ09 IEM Bluetooth Adapter, Bluetooth 5.4 Module, Wireless Waterproof Ear Hook Extra, Long Battery Life Cable for ​KZ ZS10 PRO/X/2, ZSN Pro/X, AS16 PRO, Zax,ZAR, CRA/C12(C pin) - Image 3](https://m.media-amazon.com/images/I/71ZVm4W7rgL.jpg) ![CCA KZ AZ09 IEM Bluetooth Adapter, Bluetooth 5.4 Module, Wireless Waterproof Ear Hook Extra, Long Battery Life Cable for ​KZ ZS10 PRO/X/2, ZSN Pro/X, AS16 PRO, Zax,ZAR, CRA/C12(C pin) - Image 4](https://m.media-amazon.com/images/I/61Kq3SxkkwL.jpg) ![CCA KZ AZ09 IEM Bluetooth Adapter, Bluetooth 5.4 Module, Wireless Waterproof Ear Hook Extra, Long Battery Life Cable for ​KZ ZS10 PRO/X/2, ZSN Pro/X, AS16 PRO, Zax,ZAR, CRA/C12(C pin) - Image 5](https://m.media-amazon.com/images/I/71OW48-wWQL.jpg) ## Questions & Answers **Q: Does the case charger via usb-c or micro-usb?** A: It charges with USB-C. **Q: Can I use the KZ Pr2 with these?** A: I think you can. As long as the connection is the same on the monitor as it is on the Bluetooth part. There are two different connections. One round. One with the flat two prong connection. **Q: Would it be c pin or b pin for the zax-blackmic?** A: The ZAX has a C connector (B would also work, but not fit as flush). **Q: do I need c-pin or b-pin for moondrop ssr?** A: I would say b-pin. In my experience b-pin will work on both b and c pin iem's ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great bluetooth headphone adapters!
