These definitely look like a great option. The sound quality of the Klipsch 'buds is a tiny bit better, but the durability of the Shure SE215's is simply second to none. I've had to replace three in-ear headphones over the years exactly for the same reason: the internal cables broke. The SE215's also have a much better fit and are more comfortable, not to mention better when it comes to sound insulation. You have more choices regarding the ear tips, too. I'll definitely be picking these up on Friday or Saturday.
Thanks a ton for the recommendation.
