Pros: Amazing all around sound, superb bass, mids and treble, cool and modern design
Cons: Nothing for me. Non-detachable cable might bother some.
I'm not that much of an IEM guy. That said, I needed some IEMs as I sometimes travel. I wanted a good all-rounder, something with which I could listen to music on my phone and also play games on PS Vita.
I didn't want some "decent" IEMs though. I had those (Sennheiser CX-300 II, Audio-Technica ATH-CKX9IS) anyway. I wanted the best IEM out there. I've tried two that are said to be the best, Shure SE846 and Sennheiser IE800. I wanted a universal fit and these were said to be the best. SE846 are also great IEMs but to me they looked weird. IE800s look so cool and they are so small. Yet they sound amazing. I couldn't believe such small drivers could sound so good with any genre. Sub-bass is out of this world. Just listen to Daft Punk's Giorgio by Moroder with IE800s and you'll hear what I mean. Even though I can listen to these IEMs for hours without any fatigue, there's so much detail in the sound. These IEMs don't boost treble in order to create an illusion of a detailed sound but actually sound reference class without any coloration.
Also as gaming headphones on PS Vita (or multimedia) these headphones are amazing. Games sound great, and also movies. These also work well with Meridian Explorer.
I recommend these to everyone who want the best IEMs.
