Designed in France by Focal's acoustics engineers, Listen combine all the advantages of premium portable headphones for hours of intense listening pleasure. Excellent noise isolation is guaranteed with the closed-back design and by the large ear cushions which preserve the headphones' acoustic qualities, even in noisy environments. The heat-sensitive, very high-density memory foam ear-pieces offer maximum comfort for the listener. Finally, at the source of Listen's acoustic qualities are the innovative 1-3/4" (40mm) drivers. Thus, Listen has an extremely dynamic sound, tight bass and remarkable tonal balance. These qualities are what make Listen the ideal travelling companion: listening pleasure, everywhere.
