Streaming content from a television set, audio receiver or radio device, users can individually adjust the left and right channels for varying types of hearing damage. An automatic limiting system is incorporated to reduce distortion and phasing issues, resulting in clear transmission up to 12 meters away from the base unit. Frequency response controls are also available for frequency equalization based on content type, with preset configurations for common applications including musical and spoken word programming. The A 200 also includes a secondary set of softer earbuds for longer listening sessions, as well as a roll of sealing tape for optimizing frequency response.
