Just an update.
I accidentally broke my shure cable by cleaning them..yep. the gold ring on the cable popped out which is the part that locks the earpiece securely into the cable. I should be getting a new complete pair becasue the company (addictedtoaudio) told me that the special edition cable isn't sold separately in Australia, the have requested an order but there's no ETA and I might be waiting for ever.
Iv'e used the SE215LTD's at the gym for a couple of weeks now and they isolate really really well, I have to literally take my earphones out of my ears if someone is trying to talk to me..even at low volumes. It's kinda annoying having to take my earphones out every time some random is trying to get my attention to ask whether I'm using something or not because being an around the ear style it takes a bit more effort to put them on.
also Im kinda paranoid that I may cause damage to the IEMs over time due to sweat. I don't sweat a lot but I do sweat around my forehead, either side of my face and my neck and im making a habit of wiping my face more often. Im considering to buy a pair of Sony XBA-C10's from amazon.jp for the $30ish plus postage which I was considering before.
I love my se215's and I don't really want to have to return them, I just won't be using them AS MUCH if I go ahead and get the C10's.
