“ This a relatively solid case, well cushioned, good sized and very functional. Given that - I am at a complete loss as to why the closure is so poorly made. I bought 2 of these and within 60 days BOTH case latches developed a lateral crack running along the clasp left to right - in one instance it broke off completely. I had bought them from Sweetwater and they replaced both of them...” --Lifter59

I mean, I based my decision to buy the most expensive earphones I had ever owned solely...” --Checkbox G

“ I personally prefer the sound of the "Westone" series to the "UM" products. I use my IEM's for listening to pre-recorded music. The sound of the UM series is very good, but the WESTONE 4R is the closest I have come to the sound of my FOCAL speakers.
