The Who's Townshend on iPod and Hearing

Rocker Townshend cautions iPod users on hearing loss to turn down their MP3 players otherwise to avoid damaging their hearing. According to the article, Townhend’s hearing loss is from wearing earphones in the recording studio not from The Who’s loud concerts.
There’s a comment from someone who probably didn’t read the article closely as the comment focuses on loud concerts instead of earphones.
