Grigoriy Chausovsky, from Zaporozhye, said his condoms came fitted with a special sensor that registers when the condom is put on.
It transmits a signal to a miniature speaker in the base of the condom which play a melody.
He told local media: "As the sex becomes more passionate, it registers the increased speed of the movements and plays the melody faster and louder."
