Yeah right in-ears isn't meant for portable outside use at all where some type of noise is present most of the time.
It's not like most people use them on their commute, when they go to the gym and in their noisy office. That's the place people use open back headphones see.
No problem for me using the IE800 with comply tips, over-ear fit, not falling out and above average isolation. The isolation and fit could be better, but to say this (and light weight?) automatically makes them a Sony 7550 is rather nonsense. The biggest fail is the microphonic cable and the placement of the strain relief. Microphonic cable is unacceptable in my book, but it can be tempered with an over-ear fit. From what I've read a lot of people struggle using them this way so it's probably going to be a deal breaker for many people.
The sound is still the best I've heard in a in-ear. The mids are some of the best I've heard in a headphone period. Super clear and detailed, but at the same time no hint of analytical dryness. Just beautiful and effortless. The high manage to stay clear and detailed without being overly harsh or strident. The treble is not as good as the mids but still decent. The bass is textured, extended and with the right kind of fullness and impact. The only thing in the presentation that stands out is the deep bass boost which is intended I suppose as a deliberate counteraction of the drowning out effect, and it works as intended. I understand if some bass sensitive people consider this a deal breaker.
Not sure what kind of words Sennheiser used when marketing this in-ears, and I don't give a schiit either, because they managed to create an in-ear which makes
music sound fantastic. It's rare to find a headphone of this technical ability which is truly an allrounder when it comes to genres, and I listen to just about everything apart from Diana Krall.
If you want to praise Sennheiser, I gladly show you the direction to Amazon, but our niche market (professionals and hifi-enthusiasts) would not seriously want to pay that kind of money for the flawed IE800.
I'm with my Swedish fellow man here when I say you very much sound like an elitist ******.
