Plug earphone or a concha earphone

摘要

The invention relates to a plug earphone with a front portion and a rear portion, wherein a flexible plug can be placed on the front portion which includes an outer portion and an inner portion. An electroacoustic transducer is arranged in the rear portion, wherein the front portion is positioned on the electroacoustic transducer and on an opening of the rear portion produced in this area. To achieve a reliable acoustic friction piece which is easy to manufacture, the front portion, and optionally an inner portion and an outer portion, together with a front wall of the rear portion, forms at least one radial channel leading from the interior of the front portion to the outside, and an acoustic friction piece is optionally arranged in the radial channel.
