Look, you want perfect sound, you need isolation from noise. For that you need an IEM, but anyone who spends a decent amount of time listen to them knows, you're ears will ache eventually. Now sure you can pay a bit more and get a custom made earpiece, but really, you bring that thing into the office with you and you're gonna look like an idiot.

These ear buds look like anything you might buy anywhere. You plug them in and no one would know them from something that came in the box with their phone or i-whatever. But you'll know...you'll know because it will seriously sound like the musician just unpacked his instrument, and started playing it right in front of your desk. These things meld with the sound in the room like open air cans do, so you don't get sound isolation, but if you're at work, you don't really want that. They isolate enough not to bother the guy in the desk next to you, but if he turns to get your attention you can still hear him. They are perfect from an office politics standpoint.

Considering that they aren't IEM's the sound quality is magical. Open, precise, neutral, and transparent. A little base light but nothing that can't be fixed with a little EQ there if you prefer a little more thump. They don't distort no matter how much base you throw at them.

Sure they are high impedance and they need to be driven hard. You can still hear them fine without an external amp, but they are going to be noticeably quieter then most any other earbud you could buy, and if you want to hear their full potential you simply need an amp. Most would say you need an amp no matter the sensitivity or impedance of the headphone/bud...but I see it as all relative and these simply relatively need an amp.
