As someone who makes a living as a DJ, these earphones had overwhelmingly superior sound quality, and I've been using them extensively for about a month. However, I recently lost the earphones themselves, so I am reluctantly putting the earphone case up for sale. I hope someone who needs this case will take it. This is my first time listing, so there may be some awkwardness, but thank you for your understanding. --Product Description-- Features a magnetic fluid driver, a first for wireless earphones.
