Dang - finish peeling off
I used my UE 700s yesterday during my weekly lawn cutting duties, which tend to be a sweaty affair

. Now today I find that the silver finish on both sides is peeling / flaking off. Other than some sweat from previous outside activities, I've never abused the UEs, so I'm a bit disappointed to find out that the finish is not as durable as one would hope for.
I'm going to check with UE on this in the morning, but for now I would just note that the "liquid metal" finish is just a very thin film over plastic, and should be treated gently; save your heavy physical activity for some beater IEMs.
Edit - BTW, I am still thrilled with the audio quality of these things.
