Review: Works with Sennheiser IE200 - Worked great to hook up my IE 200 to my TRN RedChain Plus. The adapters are very small and fit snuggly.
Review: Doesnt fit er2xr - 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.
