Denon-exclusive FreeEdge driver design, usually reserved for ultra-premium headphones, cancels out unwanted resonances to provide detailed, accurate sound. Soft, pliant surround materials allow the drivers to deliver crisp highs, deep bass and precise imaging without flexing or distorting the music signal, ensuring the best possible acoustic experience.
