i wasn't too crazy about either of them to be honest. the kraken's build quality was a bit better than the megalodon
, but the mic quality was meh.
the megalodon had to be broken in a for a while before the 7.1 stopped sounding hollow. it wasn't a huge drawback, it just took a bit longer than anticipated
if you truly want good quality, test some hi-fi stereo models before going with razer imho. sennheiser, audio technica, beyerdynamic
