Somehow the iems that I have used the most this year are a pair that I bought for under £20. The klipsch image x1 (s2). They aren't brilliant by any means but through a combination of factors have turned out to be the pair that I have the most hours on. Got my three main pairs (klipsch x10i, westone 2 and Triple fi 10) reshelled to save on tips but due to poor fit have had to go back a second time. As I'm in uk and fisher are in the states, this takes about 4 weeks each time!). Keep meaning to get a better pair but do what I always do when trying to make a purchase. Narrow it down to two possibilities and then paralyse myself unable to make the final decision. That's how I've ended up with a pair of £20 iems as my main beater pair right now (that and the fact that the pair of shure se215's I bought broke twice and gave up).
A sad day for me yesterday. The aforementioned klipschs finally bit the dust. Can of coke in my bag decided to empty itself over all the contents and the iems were inside. Not that bothered as they were only a £20 headphone at the end of the day it's more the timing that sucks. Another week or so and my customs should be back from their third refit!
