Thank you for viewing. I am selling wired earphones that I found while organizing my house. White earphones: Lightning earphones made by Elecom. Sound was produced. I confirmed that the volume up and down on the remote control work properly, but I have not checked the microphone. Yellow earphones: Unknown manufacturer. I have confirmed that sound is produced. As mentioned above, I do not know about the technical aspects of sound quality, but I have confirmed that both produce sound. However, since they are old, I am selling them as junk items. If you are okay with this, please consider purchasing. Thank you.
