Razer Seiren V3 Pro
Overview
The Razer Seiren V3 Pro is a professional-grade dynamic USB/XLR streaming microphone designed for streamers, podcasters, and content creators who demand broadcast-quality audio. Featuring a 30 mm dynamic capsule, dual USB-C and XLR connectivity, and 32-bit float support via Synapse, it delivers pristine audio with an ultra-wide dynamic range.
