※ Please check the third photo. After removing the yarn that was wrapped around the earphones, there are marks as shown in the photo. I have confirmed that there are no issues with the operation. Retail price: 1980 yen I would be happy to answer any questions about the condition or discuss a price reduction. The following is quoted from the product page: A classic earphone born from new research results for playing games and VR content that reproduce the directionality of sound using binaural technology. This is the birth of a new "classic" earphone born from research on the differences between sound sources created using 2-channel stereo and sound sources created using binaural technology. It was widely known that when listening to sound sources such as games and VR created in binaural with conventional earphones and headphones, a unique sense of discomfort occurred in the high frequencies. Researchers involved in acoustics had grasped the cause of this, but there were not yet many successful examples of countermeasures. This time, as a result of taking countermeasures to the problem with a new approach, we were able to create earphones that allow you to feel the sound color, spatial image, and directionality intended by the creator in sound sources such as games and VR created in binaural.
