I'm not a fan of them, but if they are cheap enough, fit you properly and you like them, then go ahead.
As with all posts like this, the best kind of headset is the one that fits you best. It doesn't matter if you prefer DC's, Peltors, Sennheisers or Bose's, certain designs fit certain people better, which is why the perenial argument about which headset is better is a bit daft.
Try them out and make sure they work properly and make sure they aren't being sold because of any problems.
