I liked my old Etymotic er3xr but they didn't have wifi. Since I use it when I'm doing something noisy like working in the garden, the wireless connection is a big plus. So much so that I used a sure bluetooth receiver with my etys which ended up breaking them :(Then I discovered that the ety _finally_ has a bluetooth option. I love these things, great sound quality, fantastic isolation and now this wireless capability The only issue I have is that they don't (ironically) have long enough cords!The Bluetooth adapter was better in that regard, otherwise it's fantastic.
