For Sale one pair of MrSpeakers Alpha Prime closed Planar Magnetic headphones with 4 pin XLR connector. They are near mint. The package includes the felt dots for adjusting the sound to personal preference. I never used them so they are unopened. They also ship with the included MrSpeakers headphone rack. If you need another connector besides 4 Pin XLR you can order from MrSpeakers or many other after market cable companies.
