The bass is decent but it muds up the rest of the audio.
The high end is a bit off compared to the mids.
Ear fit is great. I have large ear canals (especially the right side) and the standard size does a pretty good job.
They have a unique design which is nice at times and at other times weird. The left speakers is on about a 1 foot cable from the split and the right is on a 2 foot cable from the split. Its nice when you keep in the left while keeping out the right so you can hear if some one comes to your desk and that keeps the cable out of your way while typing.
They do a pretty good job of blocking outside noise in an office likes sales people and office printers.
I would give them a 3.5/5 for price to quality.
