Thank you for viewing. This is a Hi-Res compatible earphone from FiiO, equipped with a dynamic driver, so it delivers high-quality sound. You can enjoy a three-dimensional sound quality, with excellent high frequencies as well as solid bass. It's also suitable for gaming. The condition is as good as new. I purchased it new and only opened it once to check the operation, so it's practically unused. - Brand: FiiO - Model: JD3 - Type: Dynamic Driver In-Ear Monitor - Hi-Res Audio: Yes
