For hobby and leisure use, e.g., as a karaoke microphone for singing fun with family and friends. Adapter for connecting to stereo systems, mixers, etc., with a 6.35 mm audio input. When you don't want to be heard: practical on/off switch for quick muting. Connection cable (2.5 m) with a 3.5 mm jack: plenty of freedom of movement for the right moves even with a cable. 3.5 mm: for connecting to speakers, for presentations, performances, and singing in small settings. 6.35 mm: for connecting to amplifiers, for larger events with a more professional setup.
