I haven't clogged my 4.A, I clean it semi-regularly, but its tubes will never be as clean as on the day I received it. For that reason, I've sometimes wondered if a universal with custom silicone tips couldn't be the best of both worlds: comfortable, easy to clean, with good isolation. A problem I can see (and did see, on pictures) is that it can make the IEM protrude quite a lot more than seems strictly necessary.
Of course, some universals fit so well, custom tips may not be needed at all. I tried many (many many many) tips with the Etymotics models, never to my satisfaction, until very recently, when I tried the Atrio's tri-flange on it. It was perfect. Better than on the Atrios themselves, actually, because the suction of the tips can create a vacuum seal that provides great isolation but prevents the Atrios's dynamic driver from moving (i.e. no sound at all), while this problem doesn't occur with the HF-5 and ER-4 models.
I have custom tips for a universal and they don't change too much for me. Actually, they improve the sound in certain aspects and make it worse in others. Using a hearing aid dryer is really the best way to protect your investment; they are heavily used in the hearing aid industry for a reason! And nice find on the tips for the Ety's.
Joe can you give a view as you have the nt-6, nt-6 pro and ls8 with multiple cables such as the magnus and twag2.
Yes, it has to do with the size of the sound tubes in BAs, but the filters also are a significant failure point. Dynamic drivers just appear to be more robust unless you regularly care for the BA in a high humidity environment. My SA-12 failure was probably in part due to lack of using my hearing aid dryer for some time since I just left it in my gym bag.
So close but yet still so far. I'm now convinced that it's the part where it hooks under the flap at the top of the ear that is now the problem. Tried these on and off at work today for longer periods and always got uncomfortable. However my ear canal feels absolutely fine in comparison. In the past it always felt sore after about half an hour. Just feels like it really digs in there. I know the idea is for it to "lock" under the skin but it feels like it just needs reducing a bit. Been in touch with Lee so will see. Right ear feels fine as long as I get the insertion correct (ooer!). When it was sealed properly I finally began to get a good idea of the sound. How long would you say these need to be considered run in? So far all things considered I think I'm on about 5-6 hours in total.
That stinks, but at least you are getting closer. I hope once you get it right everything fall into place and you can just enjoy your music! As far as run in, I honestly can't recall exactly, and 5-6 hours could do it, or it may take 100, which is my typical burn in time. You can just let it play music 24-7 for a week or so and that should be plenty.
Do you happen to know of a CIEM that's brighter than SE-5 in the highest end? (>4.5k)
I'm talking around 6 dB/oct brighter (meaning notably), but not as bright as Brainwavz B2 / Fisher Audio DBA-02.
Tiny bit lighter midbass and more forward 1-2k mids as well if possible. General sound quality preferably on par (will be hard to match in bass and subbass).
If it helps, here's the graphical representation:
The extreme subbass and super highs (>17k) are less important. The high dip is centered on 14 kHz.
Similarly sounding headphones are also acceptable if you happen know any.
The ACS T1 Live! comes to mind, and I do compare the two in the T1 Live! review.
