Pros: Designed for and tested with Macs Reliable Manufacturer Decent Price Installed in a Late-2011 MacBook Pro 2.2ghz Core i7, immediately detected. VMWare Fusion flies, and my laptop is a great power machine with the i7, 16gb of RAM and an Apple SSD

Cons: The RAM Packaging isn't reusable. Not enough to knock a star off, but it would be nice to have a reusable container so I could put my old sticks in there

Pros: Easy setup with my Macbook Pro running OSX Lion Main reason why I bought this was to control my xbox. Had to reprogram a couple buttons, but it was a snap. Setup my TV, Xbox and Cable Receiver in less than 10 minutes!

Cons: Not even CLOSE to refurbished or recertified. Deep scratches down the back, scuffs on the front. For the price I'm not too upset, but am upset at the misleading condition statement on NewEgg.

Pros: Can give you a headache with less than 30m of use!

Cons: The entire headset

Overall Review: My current headset is a Turtle Beach XP510, which has been working great. I wanted to upgrade to something completely wireless, and noise cancellation seemed like a huge plus. After I got the headset, I let it charge overnight, then upgraded the firmware of the transmitter and headset before trying them out. Within 5 minutes, I was instantly regretting the decision of buying them. While most wireless headsets have a slight hiss to them when there's no noise, the Elite 800X has the worst hiss out of ANY wireless headset I've ever used. On my XP510s, I can't hear any hissing, but the Elite 800X was extremely loud. To give people an idea of how loud the hiss is, I had paired the headset with my iPhone and played various music at 60% volume (no eq settings or anything on the phone). During every song, I could hear the hiss over the music. I also played two rounds of Big Team Battle in Halo: MCC, and the hiss was audible through the majority of both games, with the game volume at 100% (it seems like game sound is quieter than bluetooth for some reason?). After two rounds of Big Team Battle, I got a headache and had to quit using this headset. Noise cancellation worked great at blocking the sound of my AC, but just made the hiss louder. I had read some of the other reviews regarding the mic volume, I can't give any input on that since I didn't bother trying to use the mic after hearing the noise these were making. To be honest, if I could wear the headset without getting a headache, I would most likely have kept the headset. This supposedly comes with a dedicated toll-free concierge line, but you won't find that number in any of the documentation that comes with the headset. They include a piece of paper that says there's a toll free line without giving you the number. Since my XP510s have been working great and I haven't had any major issues with them, I figured the more expensive turtle beaches would at least be on the same level of quality. If this was a $150-$200 headset, I would probably give this a 3/5. Given the fact these cost almost as much as the consoles they were designed for, they should be almost flawless, but Turtle Beach really messed up on these. I'm returning them back to the store I bought them from.
