Summary: For notebook users or those that want something to use while exercising they work great. Have had them for almost 2 years and I am constantly forgetting I have them on so they get yanked out at least once a week - still working:)
Pros: Hang in ear, one size fits all. Comfortable and sound better than the speakers on the Notebook. Very inexpensive - so quite good for the price.
Cons: Since they don't fit tight in the ears there will be less bass
Excerpt: These aren't the loudest earbuds out there, but for $[*] they serve as a good secondary pair for occasional use. I keep mine in my camera bag, so if I have some downtime between shooting, I can listen to some music on my smartphone.
