I was able to get a pair of Ultimate Ears Triple Fi 10s on Amazon during their Gold Box sales for $100. They retail at almost $500. One of the greatest purchases I've ever made.
I got a pair too, probably the better of the earbuds out there. I don't like the wire though, too stiff. Sound wise they sound fine but I don't seem to like the sound that most audiophiles do, to me it's bland. they don't hold the air tight seal in my ear too well however. I paid around $150 a year or so ago and plenty of sources to find them far below msrp, no clue where they came up with that price from. I only use them when I mow my lawn cause I don't want to advertise any kind of well known brand to my neighborhood. Their ok, I'm not wowed by them.
I also had the Bose in ear, I like the wire better however the sheath grips, so when it tangles up it tends to cause friction making it harder to just pull the wires to untangle. How it sits in the ear is very comfortable, but can still fatigue after a while and doesn't hold an air tight seal. Sound had a little more warmer sound which I prefer but they didn't stay in my ear well at all, gave them to wife but she ended up replacing them with skull candy cause they were in Pink...priorities ya know.
Ideally, it's a custom made mold so you have an airtight seal that makes all the difference to any in ear buds.
Speaking of Beats, I think the solo on ear versions do fatigue a lot more than the Bose on ear's which I found pretty comfy for long periods, not sure which I prefer better. People like to bash both brands but they should understand that some people just prefer their warmer sound characteristics.
