Hosa YMM-492 — Air Travel Headphone Adapter
YMM-492 Overview
The Hosa YMM-492 is a compact headphone adapter engineered to convert dual 3.5mm TS mono phone jacks to a single 3.5mm TRSF stereo phone plug, making it purpose-built for use with personal headphones on international commercial airliners. The dual right-angle 3.5mm TS plugs insert cleanly into the twin-jack armrest connectors found on airline seat audio systems, while the female 3.5mm TRS jack accepts standard headphone plugs. It is a practical carry-on accessory for touring professionals, broadcast personnel, and frequent travelers who rely on their own headphones in-flight.
The right-angle orientation of the dual TS plugs reduces strain on the adapter connection at the seat, keeping the profile low and minimizing the risk of accidental disconnection during use.
