Tonal Profile
The cult-classic analogue Kraken: 50 mm drivers, cooling-gel pads, one 3.5 mm plug and no electronics of any kind. The USB variants of the same shell (Kraken Ultimate, Kitty) are different products with a built-in DAC and do not belong in this comparison.
Amplification Warning
Whatever the missing unit turns out to mean, 32 Ω at 109 dB is loud from anything with a headphone jack. Treat the sensitivity figure as approximate: see the spec claim below before you use it in a calculation that matters.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Sensitivity (@1 kHz): 109dB»
Sensitivity in decibels means nothing until you know the reference: per milliwatt or per volt. Razer names it where it chooses to — the BlackShark V2 sheet says «100 dB SPL/mW, 1 kHz», the Kaira X «96 dBSPL/mW» — and omits it here. Read as dB/mW, this 50 mm driver would be 9 dB more efficient than Razer's own esports flagship; read as dB/V it works out near 94 dB/mW, which is exactly where Razer's labelled models sit, so that is how we store it. The two readings differ by a factor of about five in the voltage your source has to deliver.
