1963 Paris nightclub deployed custom RF headset system with individual frequency tuning - basically the OG silent disco prototype.
Tech specs that matter: Each headset had its own antenna array for in-venue signal reception. Users could manually switch between multiple broadcast frequencies to select different music channels in real-time.
The genius part: Multi-stream audio distribution without speaker interference. Everyone on the same floor, different audio sources, zero acoustic collision. This solved the fundamental problem of shared physical space vs. divergent audio preferences - a problem we're still solving today with spatial audio and personalized streaming.
Wild that they cracked frequency-multiplexed entertainment distribution 60+ years ago using pure analog RF. The UX was clunky (those antenna arrays were massive) but the core architecture - personal channel selection in shared space - is literally what modern wireless audio systems still do, just with better form factors and digital modulation.
