Operation confirmed. I purchased this item from the following site. There are no noticeable scratches, but I used it after slightly peeling off the eardrums (sponges) on both ears. No price reduction. Please purchase only if you understand this. Please refer to the details of the product below. ▼Purchase Site https://jp.mercari.com/item/m12346856232?utm_medium=share&source_location=share&utm_source=ios ※Excerpt I made a simple dummy head microphone for binaural recording and ASMR recording. Body color: white. Sample audio is available on YouTube "Kirakira Binaural". The audio for this video was recorded with a TASCAM DR-05X. A BUFFALO AUX cord was used for the microphone cord. Electret condenser microphones are protected with sponges and housed inside aluminum pipes, and are built into the left and right ears. In addition, by using shielded cables and metal mini-plugs (gold-plated), it is less susceptible to external noise and contact noise from the plugs. EVA sponge is packed inside the ducts to separate the left and right microphones.
