Summary: So, I've had the chance to try the pair my uncle owns, both in noisy (busy streets of Vienna) and silent environment.
You probably should take this with a grain of salt as I can only compare this to my good old HiFiMAN HE-400i, which is basically a totally different world.
Let's get to it, shall we.
Pros: Nice bass, detailed sound, very good for rock, nice (removable!) cable, punchy bass and highs hitting at the same time
Cons: The bass disappears when going very deep, doesn't stay in my ears with either of the ear cups > sound gets fatiguing and bass totally disappears
The Sennheiser IE80. I would like to start with stating that I am not an audiophile. However, for the past years I have had my fair share of headphones/earphones and I have been involved with the audio world for some time now.
Nice looking but not really so convenient hard case with tight space for the cable. Most of the tips are useless; There are no mid size foam tips (that most people use), just large and small foam and silicon tips are in all three sizes but others are really useless (odd shape, no isolation...
Pros: Good soundstage, great build and durability.
