These headphones pair the excellent acoustic qualities of the wood with 50 mm neodymium drivers. One listen, & you&0ll agree that it&0s a good match. Griffin Wood Tones headphones impart warm overtones that accentuate the mid-range. Vocals come alive, & low frequency bass emerges without distorting harmonics or clarity-destroying echoes. You&0ll notice an improvement in sound volume, as well; you may find yourself listening at a lower volume level than usual, yet enjoying it more.
