Great purchase
Amazing sound, especially for the price. Case is larger than current earbuds on the market but really I'm splitting hairs

Wireless IEMs? Absolutely
Didn't have the best expectations for this kit but wow. They connected with the transmitter for my iPod classic no issues. My KSTs fit perfect and the sound is great. They feel better than the quality of my wires that came with the KSTs and feel like they are durable for Everyday use. Time will tell.

Great value to make use of existing IEMs
For some ~10 year old Alclair IEMs, these were cheaper than a standard cable. As I'm not touring anymore, I just wanted to put the IEMs back to use as headphones... To make them work, I had to shave down the plug area as the B-Pin style didn't fit in the jack recess on the Alcairs, but after that modification, they work fine and are snug. Sound quality streaming audio from an iPhone is just fine. It's not perfect, but for the price point, I'm completely satisfied. The case was a bit of a bonus for me when I saw the IEMs should fit in it as well, unfortunately these custom molded IEMs don't both fit while still connected to these adapters, so I need to pull one and just left the IEM sitting in the case. Not the end of the world, but not ideal.

Extremley worth it but a few design flaws.
Sound Quality is decent, but not the same as when using a regular 2-pin. Battery Life is amazing 2 weeks in. On certain iems the pin does not fully secure itself in, but the earpiece sits nicely around the ear so it works out. (For refrence I have used it with Truthear x Crincale reds and blues) Overall, for the price its really good and pretty comfortable.

Super light with great fit and sound
Pros: super light, great fit, good sound quality, easy pairing, good value Cons: none so far, will update if any develop These are super light and they hug nice and tight, but that means they're functionally invisible to the user which is good. I bought them for the gym and paired them with a set of ZSTs (cheapest KZs I already had). Cost is just right for latest gen bluetooth imo. They drive the ZSTs perfectly well.
