The Sennheiser e900 Drumset is a wired drum-mic bundle from the Evolution Wired series designed to mic a full kit. A common configuration includes 1× e902 (kick), 4× e904 (toms/snare) and 2× e914 (overheads). The kit pairs dynamic kick/tom mics with a pre-polarised condenser overhead set, all using XLR connections and requiring 48 V phantom power when used with the condensers. Exact contents vary by retailer/box label.
