Panasonic RP-HT21 Lightweight Headphones with XBS® Extra Bass System
My life has always evolved around music and I have never before purchased headphones at this price without that "tin can" sound.
What I read the other Customer Reviews about the Bass, not only Is this true but , I was impresssed myself with the Bass.
My only complaint is, I wish I had the opportunity to purchase them at the sale price which was offered shortly after I ordered two pairs.

good for the price
The sound is very good for the price. The fit is on the loose side for my somewhat narrow head; if I'm moving around much I usually wear a cap over them to be on the safe side.
