Summary: I loved this headset for about a year - it had amazing sound quality and a perfectly clear mic, and it was only $150. Now it's a worthless piece of rubbish because Razer decided to use the world's flimsiest cable to connect the headset itself and the control brick, thus causing the left speaker to only work after fidgeting with the cable. They refused to replace it even though it's only slightly over a year old, so I'd say to avoid Razer at all costs.
Summary: I purchased this about 8 months ago. Had great sound, mic sensitivity had to be set to 0 or it had feedback (I tend to leave one ear off, and it picked up the other speaker like nothing else. Once I played around with it a bunch it finally sounded pretty decent. Pros: Lots of configuration, easy to switch between surround and stereo, clear mic, comfortable Cons: 8 months later and something disconnected in the headset disabling first the right ear and now both.
Summary: I ordered this on June 26th, 2012. Have worn it and used it regularly since. While it is a good product, the headset audio randomly stops working. If I unplug the USB and plug it back in, it works just fine again. I have the latest drivers (Pft, from 2011...) but this still occurs. I'm not sure how to fix it, and all Razer Support does is send me their copy & paste email support BS. I just want a headset that works, that I don't have to re-buy every 2-3 years.
Summary: The drivers are horrible for windows 8. they keep disconnecting. had to warranty it after 10 months because of the wire shorted out, now it has shorted again. if im going to drop 140 for a head set it better last. i have had a Logitech mouse for 2+years and it still runs great. Prolly going to get a Logitech head set now to replace this. It was a great headset when it worked but it dosent last so i wont buy again.
Summary: Ear cups are way too uncomfortable. Software had a god awful and HORRIBLE screeching ring sound on the microphone that only went away with drivers, and even then there was allot of white noise on the mic. Pod also get very hot for what basically seems like a volume control/digital mixer. My turtle beach DSS does the same thing, is about 25% smaller and lighter, and never gets hot. You cannot justify this headset for even $80, let alone $150.
Summary: I got these because i needed a good headset for when i game. The megalodons do just what i was looking for good speakers(the 7.1 is okay really only turn it on for FPS) but the 2.0 does sound pretty good. They're also pretty comfy to wear for awhile. The mic needs a bit of tuning but once you get it adjusted it works well. It comes with a case which is pretty nice because i also use these for work. TL;DR Good sound, 7.1 sounds weird. Mic needs adjusting. Comfy.
