The Razer BLACKSHARK V2 HYPERSPEED is an ultra-lightweight gaming headset with a battery life of up to 70 hours. I am selling it because it didn't suit me, even though I used it a couple of times after purchasing it new. I think it's in near-new condition as I haven't used it much, but please refrain from purchasing if you are sensitive to used items. - Model Name: BLACKSHARK V2 HYPERSPEED - Brand: Razer - Battery Life: Up to 70 hours - Driver Size: 50 mm - Weight: 280 g - Microphone: Razer HyperClear Super Wideband Mic Thank you for viewing.
