Abstract
To both ends of a frame constituting a lateral pressure structure of headphones, support sections functioning as fine adjustment members for performing fine adjustments to the lateral pressure structure are attached. Paddings are provided on one of the ends of the support sections. When the headphones are worn, the paddings come into contact with a user's head. Earphone arm support sections are provided towards the tip of both ends of the frame, and earphone arms are rotatably connected to each of the earphone arm support sections. Earphone capsule sections are provided at the ends of the earphone arms. When external sounds need to be heard temporarily, the earphone capsule section can be released from the user's ear by rotating the earphone arm while the headphones are still worn on the head.
