First Claim
1. Headphone apparatus for comparing a reference performance to an independent performance of a musical work comprising:
- right and left earpieces each comprising a generally cup-shaped casing adapted for covering the ears of a listener,first and second speaker means carried within each of said earpieces,coupling means connected to said first speaker means in each earpiece for coupling a first source of audio frequency signals representing said reference performance to said first speaker means, andelectronic signal processing means, including amplifier means, having an input adapted for connection to a second source of audio frequency signals representing said independent performance and outputs connected to said second speaker means in each earpiece for coupling said second source to said second speaker means.

Abstract
An improved quadraphonic headphone arrangement in which a first audio signal is coupled to a speaker in each headphone and a second audio signal, usually monaural, is coupled to an amplifier and then to a second speaker in each headphone. Switching means are also provided so that the second speakers may be connected directly to the second audio source without amplification. The headphone is used as a musician'"'"'s practice aid or for track-making or similar purposes. A prerecorded signal is coupled to the first speakers while the musician'"'"'s electronic instrument output is coupled through the amplifier to the second set of speakers.
