How long did your Megalodon last, anyways? Specifically speaking.
As for what I am going to suggest... no Razer, SteelSeries, Logitech, Plantronics, or other plastic gaming peripherals toybrand will come even close to. These are professional grade audio products made by companies who have been succeeding in the business for a far longer time. They focus purely on audio products and nothing else. They are used by all your favorite musicians, movie-makers, the creators of the sounds/music in your favorite video games - you get the idea. This is top notch quality stuff and not nearly as expensive as some would think. And do mind, for music, none of those gaming headsets will be nearly as optimal as these.
If you have $150~ I'd suggest a pair of
Audio Technica ATH AD700 (great for gaming and music, though slightly lacking in bass I hear) and a
Zalman ZM-Mic1 clip-on microphone.
Other great headphones you could consider in the same price range would be....
Sennheiser HD 280 Pro
Shure SRH 440 Professional Headphones (I use these, love love love them)
AKG K240 Studio Headphones
And of course there others from these brands you can look at, these are just the most often suggested. The most popular amongst the regular posters here on the computer forums would be the Audio Technica ATH AD700s, Shure SRH 440s, and AKG K240s.
