The Yaesu YH-77STA light weight, open air stereo communications headphones have dual samarium-cobalt transducers with 103dB/mW sensitivity. They allow easy signal separation during dual receive. They are designed primarily for use with the Yaesu FT-900, FT-990, FT-1000D, FT-1000MP and FT-1000MPV transceivers, but will also work with most newer communications receivers that support a stereo jack. Adjustable.
