These are Beyerdynamic earphones☆ I've loved the sound of Beyerdynamic for a long time, and I bought these as soon as they were released. However, I haven't had much opportunity to use them, so I'm selling them to someone who will appreciate them while they're still in great condition☆ I've only used them at home, once or twice. The sound quality is, needless to say, incredibly good☆ They are in like-new condition, but please refrain from purchasing if you are overly concerned about minor details☆
