Please be sure to read the profile before asking questions or making a purchase. ZERO AUDIO ZH-DX210-CB Wired Earphones Carbo Basso BANECHO Black Earphone Case Headphone Clip Set My family used these a few times, but switched to other wired earphones, so these have been stored at home. Operation has been confirmed (sound). However, since my family is currently living outside the prefecture, I cannot confirm if the sound is the same as when purchased. They apparently didn't use them much, but please understand that these are used items before purchasing. Shipping will be via Yu-Packet Post Mini. #ZEROAUDIO #WiredEarphones #EarphoneCase
