Quiet Events—which provides wireless headphone rentals for silent discos and has offices in Los Angeles, New York, San Francisco, Austin, London, Ottawa, and Tokyo—offered a meeting-friendly idea during the trade show's morning education sessions. Because four workshops were happening simultaneously, with only draping separating them, the headphones were used to ensure audiences could hear the sessions. Speakers spoke into a microphone, which fed directly into the headphones that had been provided for each attendee. The headphones can be customized with company logos, and they work as far away as 1,500 feet from the speaker and have a 12-hour battery life.
