Note: Cable connector is Female XLR 4-pin, incompatible with standard amplifier output connectors. Due to pin-out arrangement and 0.3Ω load, do not use adapters or connect directly to amplifiers — this will destroy both amp and headphones. Connect only to RCDI-32, RCDI-8, RCDI-Viva, or specialized Direct-Drive Amplifiers for RAAL Headphones (HSA-1a/b/c, VM-1a, Jotunheim R).
