Highly recommend upgrading. I had three pairs of E3s back in the mid noughts. Cable went out twice, was replaced twice by Shure under warranty over several years. I bought the se425 a couple years later and they are probably the finest value headphones I've ever owned (versatile, dynamic, accurate, quiet) compared to RS1s and HD600s, and the replaceable cord is undeniably elegant
The Brazilian representative for Shure refused to replace my phone at the time and I decided to just let it go.
I did not simply upgrade at the time partially because I was at odds with Shure because of this. Ten years later, the anger has faded, and I'm considering them again.
Would you say that a SE215 (their lowest-priced), has a good isolation? I'd use it mostly for podcasts, so I don't care much about sound quality.
Wow, that's too bad. I remember the warranty process being a breeze. They sent me two new pairs; the cable was crap and always failed before 2 years so I did feel like they should make up for it, but I would in no way say that they didn't treat me fairly or I didn't get my money's worth. Sounds like they care more about their US customers :/
I'm on my fifth or sixth pair of Shure Se215's now. Awesome sound, isolation and fit, but eventually the connectivity between the ear buds and the cable will start to fail. (6 months to 1 year). I will probably go for a different brand without detachable cables soon, since my current ear buds are starting to fail again...
For the ultimate silence on airplanes you can put some Bose QuietComforts on top of the Shure buds.
