Summary: Final line, for the price you can't beat these. I bought these to replace a set of high priced Plantronics headphones, and am extremely happy with the purchase.
Pros: These headphones have very good sound quality, rich base and treble. I've heard better quality in $200.00 headphones, but I honestly have yet to find a headphone with better sound for under $120.00.
Cons: They are a little heavy due to the high durability of the components, and the ear phones could be a hair larger (to reduce ear pressure), but they are nicely padded so as I said above, I can wear these for 6+ hours without issue.
