Razer Arctosa

Engineered with industry- leading gaming technology from Razer, the Razer Arctosa comes with outstanding features  like fully-programmable Hyperesponse™ keys with macro capabilities, customizable software profiles with on-the-fly  switching and 1000Hz Ultrapolling™, giving you the competitive edge to perform faster and better in-game.  Say goodbye to amateur hour; your gaming abilities can be brought to the next level now.
	Slim Keycap Structure with Hyperesponse™ Technology The Hyperesponse™ keys of the Razer Arctosa reduce key latency and maximize response for critical actions during competitive gameplay ensuring fast, accurate and consistent actuation response in the intense frenzy of competitive gameplay.
	Selective anti-ghosting capability around WASD gaming cluster  The Razer Arctosa addresses "ghosting" signal failure that occurs when you press multiple keys simultaneously on traditional keyboards. Selective anti-ghosting around the WASD gaming cluster on the Razer Arctosa allows more commands to be entered at any one time without the "ghosting" signal failure.
	Fully-programmable keys with macro capabilities Too many keystrokes to enter and too little keys? Sometimes we wish we had more fingers (or maybe an additional arm for that can of soda or beer while we're in the middle of a raid.)  The next best thing would be fully programmable keys with macro capabilities that  enable instantaneous, multiple commands with a single keystroke. Buy armor and weapons  or execute complex manoeuvres with a single key with the Razer Arctosa. Some things are  better than extra fingers (or arms).

Razer Megalodon

Razer's latest headphone product is dubbed the Megalodon. Behind the odd name hides a well performing USB headset with all the usual Razer trimmings. The Megalodon features a driverless USB sound card and has a neat little control box that allows you to control all aspects of its performance.
Right out of the box, the Megalodon reminded us of the Carcharias. You'll find both headsets carry the same basic design. The Megalodon is outfitted in a stylish all-black design--from the headband right down to the boom microphone. The ear cups are large, padded, and easily fit entirely over our ears. The soft foam headband makes for an even more comfortable experience while the adjustable wire-framed sliders helped mold the headset to our head. The outer ear cups are covered in slick, dark metal grilles with the Razer logo emblazoned on each side. Like the Carcharias headset, the Megalodon is large though it's surprisingly lightweight, which allowed us to have extended sessions of play time and chatting.
On the left ear cup you'll find the protruding boom microphone that can swivel 270 degrees around--completely out of sight if you'd like. With that feature, we have no hesitations about recommending the Megalodon for use with other media other than gaming.
