would driver flex finally kill a pair of IEM ?

What do you mean by "driver flex"? Can you specifically describe what you're experiencing?

right out of box i experience the driver flex on both ear pieces, the flex is much worse than my last pair of jamz.

 

do all the closed IEMs have this driver flex?

You don't have to pay shipping back to monster for warranty repairs. Just explicitly ask them for a shipping label and they'll email you prepaid FedEx postage. 

The Jamz have a bit less driver flex than most closed IEMs but the Golds weren't too bad when I had them. There are others that have even less flex (e.g. Hifiman phones, Senn's IE series, Atrio M8, Ety MC5).

monster ranks the worst in terms of driver flex IMO, almost every phone I have tried suffers from this issue, interestingly enough, as ljokerl has pointed out in his reviews, the higher end phones actually suffer more from this issue (miles davis tributes being the best example)

I just got in a pair of IE7s and I'm experiencing driver flex on both sides. I'm getting them replaced, but I'm figuring the new pair will likely have the same problem. Is it really true that it doesn't affect the sound quality or lifetime of iems? That crinkling sound just makes me cringe thinking about what's happening to the drivers inside.

My Brainwavz M2's don't do this, but I did experience this with a pair of crappy Skullcandy Titans.

yea i think the M2's are technically ported.

that actually makes sense, though it does come at the cost of decreased isolation and more wind noise

 i agree, its like a comment sense ,  it sounds horrible when the flex happens

IE7s have a 2 year warranty, but not sure if Sennheiser pays for return shipping. I was deciding between the MTPGs and the IE7, but went for the IE7 so I can't give a good comparison to the MTPG.

What's interesting is that the IE7s are ported and they still have the driver flex issue.

Based on the other threads I've read, some people say driver flex damages drivers and others say it doesn't. I'm just wondering whether it should be a deal breaker when choosing an IEM or if it's something people just live with.
