I agree about that, but for me it isn't a "vented" seal that fixes it, it's a shallow gentle fit. But no air can be leaking or it sounds completely off to me. This might vary for different people though. I personally feel that if you need to create a vented ear tip and really finagle with the fit then that isn't a great earphone. I'm not saying I don't do things like that to get great sound. Great sound is what matters most to me. However, it makes me think less of an iem if the best sound can't be achieved by simply using them as intended.
No prob, if it doesn't work for you, simply let it be... just saying front and back venting is a common way to tune DD based IEMs, nothing wrong about that.
As for the bolded part, well it's a fact that people have different preferences, listening habits and HRTFs. How about all the filter swapping and EQing posts in the ER4S thread, does that make them lesser IEMs?
Well, now that you say it, it's not exactly a seal where air is leaking, but if I push them a bit further than the "sweet zone", the air pressure, and the vacuum on my ears feels reeeally uncomfortable and even painful, asides from the mediocre sound. Whatever, at least with the "vent mod" I just push them firmly on my ears, and it's done. No more annoying vaccuum.
I've learned that air pressure and a vacuum seal can be a big issue for some people, ranging from annoying to painful. I personally don't have this problem, but for me, if the ear canal's air pressure is exactly equal to the outside, perceived transparency is enhanced and soundstage gains a nice open feel.
The er4s "was" designed to use filters and those filters are permanent replaceable parts that are consistent and even sold by the company.
So i would say you can't compare those things really. Not to say the er4s isn't flawed in some areas, or that people don't mod them. My point was just that i think it's fine to do these mods, and i'm not discouraging anyone from trying them. I was just implying that it isn't an especially good product if an unsupported mod is required to make the sound good. Not just sound better, but from what we can tell... Sound good. Usually the mod reduces bass. If the bass variances didn't exist, most people wouldn't need a mod. That's the fault of quality control.
I liken it to something like a new computer with a broken cd drive. If you can tape the cd-drive shut to get it to work then who cares?... Well, realistically i don't know many people that wouldn't return a computer with a messed cd drive. So why should the tenore be any different?
In the real world it is probably because not many othet affordable iems sound so good. So people are willing to "tape the cd drive shut" to get it working, since the cds rip so incredibly fast or something... :-P
Anyway, point being, they sound great. Mod them if you need to. But it doesn't excuse the need for a mod like that. :-o that was all i meant.
I love modding things to improve them. But it's one thing to shape the sound with a mode. It's another to mod something to fix a problem that shouldn't be there. But i guess you could argue whether it would be necessary for someone to do even if they had a neutral set. At that point i'd say do what you need to if you like them. I was just speaking from the viewpoint that people were bringing the bass back down in bass heavy sets.
