Hmm, so i have to RMA them, sell them and buy some other pair i guess...
What would be some nice models with a non defective design to replace them?

I don't think the problem is a defective design of the EPH-100, as they're working fine for most of us! Maybe you should look into the VSONIC GR07 MK2 model or even the new GR07 Bass edition...
How does EPH-100 compare against SM3 especially in means of bass (quantity and quality)? I have SM3 and that's my only reference point, so I'd appreciate it if one who owns'em both could do this comparison...
I just recently purchased the IE80s to place them, highly recommended.
Best scenario you can do is to RMA them, get a brand new in box pair, then sell them.
Would work out a lot better for you if the next person also gets the problem, he can't blame you for selling him a used pair that has the problem, accusing you of selling it to him/her knowing of the problem.
So, you consider that the problem reported by some users (from memory, I'm sure not more than 10 users, at most) in a 188 page thread, means that the EPH-100 just works fine for some users, right? I mean, from what you wrote, the majority as problems with them? 

Well to be realistic, it is only a minority of people who have the problem.
But why do you want to risk buying a pair when a minority(a minority is a lot more than a rare case) on a forum such as head-fi.org have the problem where the sound dies, it's a big issue that's not being addressed by Yamaha. I've sent countless emails and they refuse to do anything about it. Not surprised as they won't even supply replacement tips for people who lost them. The customer representative said it was the source of the sound which is the problem, wouldn't accept the fact that when another set of earphones/headphones plugged in, it was fine.
Furthermore, due to the complexity of the problem, it's something that will take a long time to RMA if it is out of the 7 day policy, the sound dies intermittently generally after use. It won't be too easy for them to reproduce the same problem unless they have a tech monkey listening to them for a while. Even if it's just trading for a new pair, people don't wan to risk it.
Once you've been through 3 pairs like I have(most people wouldn't even bother going to that extent), you wouldn't ever go back to experiencing it again.
Got a pair of IE80s through Amazon which cost 2x the price as the EPH100s, wish I took this route earlier.
Etymotic...
Any model. They are all built well, with a great warranty.

Well, but that's just typical forum behavior... The vast majority of the EPH-100 owners without any problems don't even bother to come to this thread and say that they work fine! On the other hand, users with a problem come straight here to post about it, looking for solutions or recommendations about their problem... If you're conducting your "study" about the EPH-100 failure/problem rate based on the posts on this thread, then the results will be way off! Just my 2 cents... 
The same logic applies to people who have the problem, most won't even go on a forum to post about it, they will just be returned/RMA'ed.
The 2 people I have recommended the IEMs to, both have the same problem.
Either I am cursed and coincidentally got 4 pairs of dysfunctional EPH100s, including everyone I recommend them to.
Or people need to recognize that it isn't a rare, once in a thousand issue anymore and should be aware that a minority of people have experienced it.
It's like buying something off ebay, you wouldn't buy from someone that has a 92% rating, you'd look for sellers that have a 99.8-9% rating. Maybe not the best analogy, but you understand.
When ASUS released their version of a graphics card that came factory overclocked, probably 5% or less users reported issues regarding the temperature and heating for certain games/apps - it was acknowledged and addressed. Yamaha are most likely not going to do the same - not their primary and dominated market - IEMs.
You also have to understand that these aren't popular IEMs, they're not beats, they sell no where near to brands such as Sennheiser/Klipsch etc. available pretty much all retail outlets.
my 2 cents.
Agreed, There are problems...
Yamaha hasn't addressed it.
Time to move on.

Mine only had the low sound problem once and never happened again. I've since sold them and didn't feel it would be a problem that would happen again. It might have just been something blocking the little vent hole because if it was something wrong with say the wiring or a technical problem it should have happened more than once. I think its a rare problem so it shouldn't scare you from getting a pair imo.
Just the fact that the qualification of "rare vs minority" is discussed here, works against the reliability of the product. I think that all of you who have had problems, should get together as a group and communicate with Yamaha (not the seller, but the manufacturer) what has happened. Give them a good opportunity to respond. If after doing that, they do not to care about refunding your money or making sure that you get a good replacement, then promise them that each one of you you will write the corresponding negative review on all online places where reviews can be posted and each one of you will also post a YouTube video sharing your experience with the product. You not only owe this to yourselves, but to others who could experience the same misfortune after getting the EPH-100.
Great Advice...
