Sony Type Terrestrial Digital Earphones 5m MDE-S5B

Plug diameter: 3.5mm (stereo plug) *Size that can be used for general TVs and radios. Cord length: 5m Product Features: The part that goes into the ear (transparent part) is made of soft resin, so it won't irritate your ear holes even if you use it for a long time. For those who use it for a long time and those who have sensitive ear canals. Precautions for use: Since it is inserted into the ear canal, please refrain from using it if you have ear inflammation. There is no age limit for use, but parents should be careful not to allow small children to use the product alone, as the cord may become tangled in the body or cause damage to the ears due to unexpectedly high volume. When using regular monaural earphones with a stereo audio device, you may not be able to hear the sound from one channel or the volume may be low. This product solves that problem by mixing stereo audio (R and L) so that it can be heard with one ear. *This does not completely reproduce stereo sound. Mix stereo audio and consolidate it into one ear. When you don't want to cover both ears.
