Query: Unfortunately frustrated

I really wanted to give these headphones a higher review, though i cannot. I must admit the sound quality is superb and unmatched by any previous models of in-ear headphones i have owned, BUT the build quality does not match that of the sound. After about a month of owning these the housing on the right headphone came apart but i snapped it back together and didn't have any problems until recently. After about 6 months of regular use the left housing completely came apart and recently one of the wires detached itself from the speaker (if that's what you would call it) rendering it useless . I'm going to try and sauter the wire back to the speaker so i'll update my rating based on the outcome.
