okcsc ETYMOTIC Male to QDC 2PIN Female Headphone Adapter for ER4SR Earbuds to QDC 2 PIN Cable Lossless Audio Adaptor for Etymotic ER4SR ER4XR ER3XR ER3SEER2XR ER2SE LNO08099 KZ ZSN ZS10 1 Pair Black

They work with my moondrop Katos but I broke one after dropping from high up.

Doesnt work, even though they look similar i found out the hard way they are not compatible PS: I made it work by using sandpaper on the ER2XR, still going to leave this review with 1 star because I shouldn't have to physically modify my equipment to make a product compatible when it advertises compatibility without any modification needed.

Worked great to hook up my IE 200 to my TRN RedChain Plus. The adapters are very small and fit snuggly.

They work. No fitment issues, just a simple converter. Does the job well!

Item doesn't fit flush on the qdc end(too long). Costs too much for what it is. Manufacturer should put more effort into ensuring the item actually fits.

si por accidente dejas caer tus audifonos podrian dañarce los pines y quedar incluso atrapados en tus audifonos, es de pesima calidad el material

Pins break off easily, requiring surgery to extract from IEM. I had to drill one out. I don't know if there is a better solution but be very careful with these. Avoid any sideways/shear force or excessive pulling or pin will shear off or pull out of the adapter housing.
