Great product
Worked as expected.

Go wireless!
I had a pair of earbuds that sounded good but were uncomfortable to wear because of the cable design. Attaching these in place of the original cable made them so much easier and more comfortable to wear, and they sound terrific. I just wish the case was not quite so large.

Best iem Bluetooth adapter
Why did you pick this product vs others?:These are great. Good sound quality. Also the battery life and Bluetooth range are great. The shape is a little bit chunky on the ear hooks but got used to it - my only complaint is it was hard to find the different adapters for different iem connectors.

Many avenues for improvements. Good ones too!
What is this? Nice fit, actually, but the IEMs don’t fit the case by a MILE. I understand they’re KZ but still. Why recess the connector and make it longer. If it were shorter my IEMs would still in the case fine. 2-3mm inside near the front. You can see from the photo.EDIT: The only thing I WISH SO BAD these had is some kind of active transparency mode. Noise Cancellation is good as is with just the right tips. I just wish I could hear through them.

terribly underpowered
The build quality is high, especially considering the price, and is comfortable and has well designed controls. However it sounds truly horrid- there is *very* audible distortion/clipping at normal (not super loud) volume. If you plan to listen to music with them, you will be sorely disappointed.

Surprised by the performance
These give my iems a great experience for the price, battery life is phenomenal and can last about 8-14 hours at constant low volume.

Good
Bought these to put on some planner magnetic earbuds I got a while back, these do degrade the audio quality a tiny bit but that's just Bluetooth in general, no fault of these, these are comfy and I've never had a problem with them dying on me

Go wireless with your MMCX IEMs!
Very light, and for the hour (or so) I've been using them, they seem very comfortable (I barely feel them at all). As you can see in the attached photos, I wear glasses, and the BT adapters don't press the arms into my head, which was something I was nervous about (I really didn't want to have to return these in that case).I had zero issue getting these paired to my phone - As soon as I long-pressed the button on one of them, they showed up in my phone "Connected Devices" list, and paired without issue.I'm happy that the BT adapters, IEMs, and the foam tips all fit into the case -- every pair of ear buds I've had over the years could not fit the foam tips I use into their cases. Having to remove them, and keep them in a separate case (that I'd have to carry in addition to the IEMs/buds themselves) wasn't something I looked forward to, and caused extra wear to the tips.Only complaint I've got is that, without EQ on my BASN BSG-MC100 IEMs, the audio is very mid-bass heavy, nearly no treble - something that's pretty easily fixed.I can't speak to 'value for money', as I've only had them in my hands for a day, but so far things look pretty positive in that department.
