I absolutely love the new Steelseries Siberia v3s. They are great for the price. They have great sounding drivers and a pretty god retractable microphone. And yes they are under $150 depending on the model.
This will void your warranty, though it think getting water in it already does, but search on google on how to take apart the screen on your specific laptop. Then just wipe off the water and reinstall everything. Bam your done.
SteelSeries Serbia v2 is quite cheap on amazon right now. Theres also the bitfenix flo. or for $75 the Cooler Master Pulse-r are very very good for the price. I would recommend those two.
