The sound quality is pretty good, I expected more bass, especially considering they are "enhanced bass", but for walking around and working out they are fine.
The build quality was a little on the cheap side, but it's not the worst I've seen and the inline controls take a bit of time to get used to, but I am glad that the primary function of the up and down buttons are volume +/- rather than skipping. Also, the magnets in the earbuds is a nice touch, because it allows you to have it as a necklace when not in use.
They are comfortable, although I wish they had hooks to help keep them in my ear because they do fall out if I put my hood up or take off my jacket. Battery life is great, I got 12+ hours with just from the charge it had in it when it was shipped.
The price is a little high, but it is still a pretty good deal and if you can find any discounts it would be a great deal
