^^^lol...i also need an explaination

 

[Joe Bloggs]

Driver flex, I just found out, is when you have *too* airtight a seal between the IEM and your ear canal, so that shifting the IEM or your jaw changes the sealed volume of the ear canal, creating a pressure imbalance between the sealed volume and the outside, pressing the driver off its neutral position.  Symptoms I hear include the driver making a crinkling sound and, if the pressure difference remains continuous, everything sounding like it's underwater.
 
In other news, I can't be sure how much of the difference I'm hearing can be attributed to sealing the sound hole and how much to changing up from small to medium tips.

Couldn't have said it better myself, Bravo!!! Was listening to my FX40s last night and it's still freaking me out on how amazing they sound, it out classes the FX101 for sure, but the FX101s are for bass lover, so I can dig. 
 
@ Joe Bloggs or anyone with insight, can you explain to me what "driver flex" is and what it entails? Came across this term a couple of times and looked it up but the explanations were kinda unclear/ too technical, etc.  Can you put it in laymen terms? Thanks in advance. 

You can hear it when you insert one of the earphones into your earcanal, its a "click" sound.  think about a thin tin flexing.

Wanna try the live sound from sony cuz the frequency response looks so amazing and guessing that it will sound just as good ....its now avalible at the local sony shop.

FWIW, the cable isn't the problem on the FX40s, yes it's thin, but with care it should be ok. It's the lack of strain reliefs that hurts. One wrong pull and you'll end up with a short in them like I did.

Thanks you'll for that lesson on "driver flex", getting schooled by head-fi one term at a time.

Yup !   ...it's like you went swimming and got water in your ear canals, when you tilt your head and there a kinda poping sound in your head.
 
Actually almost all IEMs will have a certain amount of driver flex if they have a good seal and you push them in deep and hard enough.

Wait LoL, I though having/ experiencing driver flex was a "bad" thing and should be avoided no? But from what you are saying that "popping" sound as I insert my IEMs means I got a really good seal, hence would get the best isolation/ sound no? So isn't driver flex a good thing then??? Does having a too air tight of a seal really affect the drivers of the IEM, seems kinda strange cuz when there is a popping sound after I insert my IEMs it's indicative of the best seal/ sound for me hmmm.......MIND BLOWN.   LoL 

 
I guess the less I know the better ha, ignorance is really bliss heeeee.

I don't think so, with unmodded SHE3580 for example I've never had driver flex, in fact I don't see how they can possibly have driver flex since they have this vent between the driver and sound tube that vents any pressure buildup in the ear canal. It's only when I sealed this tube hoping to increase bass fidelity and isolation that I managed to induce driver flex.

Got my FX101s today, they sound pretty good out of the box, not quite sure if they sound as good as my E10s but perhaps I should burn them in? How long should I do this for?
 
Also, I keep hearing this clicking/popping sound when I insert them into my ears. Is this a good/bad thing? I'm not quite sure how far in I should inset them to get a good seal.

48 hours should be enough for them.  Enjoy your music!
