Optimized weight for extended wear Just like the Razer Electra, the Razer Kraken Pro gaming headset has been field-tested by countless professional gamers and athletes to determine the optimal weight for extended gaming sessions as well as for unparalleled comfort on the go. Fully retractable microphone The left ear cup houses a fully retractable microphone boom that pulls out only when you need it, perfect for taking your headset on the go. The flexible design allows the unidirectional mic to be adjusted to individual needs so it's always in the best spot whether you are giving strategic commands or making a quick call to your friend. Powerful drivers and sound isolation for highest-quality gaming audio The Razer Kraken Pro's large 40mm neodymium magnet drivers are tuned for clear high- and mid-ranges as well as deep bass for powerful lows. A closed ear cup deign with plush circumaural padding creates superior sound isolation so you can focus on your game or conversation uninterrupted by outside noise.
