I used to review consumer electronics as a side gig, and one year Shure was nice enough to send me one of every in-ear headset they made. This was around 2005 or so. The gear was excellent, fantastic sound quality, but they all broke. Even the $700 pair. The cable got pinched or something. Shure replaced them (even though at this point they were out of warranty), and the replacement pair broke a year later. Wires suck.
