Following the rising popularity of portable music players, The Who's guitarist, Pete Townshend, has warned of potential hearing problems caused by headphones. The warning appeared on Townshend's personal Web site.
Townshend wrote: "I have unwittingly helped to invent and refine a type of music that makes its principal proponents deaf. My intuition tells me there is terrible trouble ahead." He also blames stereo headphones for his hearing problems.
