They look like they are a decent pair especially for the price, When it comes to Headsets it's a lot about the comfort those seem to be an open ear set which is defiantly a good thing to have, Ive had about 5 pairs of gaming headsets so far, I've owned, tritons, samsungs, razor, steel series and turtle beaches, the thing I find most irritating is when my ears get sweaty, my favorite set had to be my razor piranhas. However currently I'm using a pair of xbox 360 turtle beach x11s, despite being a console headset they quality is amazing I would recommend checking them out. http://www.turtlebeach.com/products/pc-gaming-headsets/ear-force-z1.aspx
It's ultimately up to you at your set limit the ones you linked look to be of sound quality ( no pun intended -.-). Turtle beaches I know to be a well known brand of decent quality, but if you can go over your limit I would check out razer they have been bar far my favorite with quality and comfort, and they are about 75$ for the piranhas. That is just my opinion hope this helps you make a decision.
