Low-end noise canceling products usually have pretty dismal sound when the electronics are switched off, but Sennheiser's audio quality remains stellar whether they are powered or not. Even when compared to regular (non-noise canceling) products, the audio quality is on par with the best of them. At the end of the day, these are the best overall sounding earphones I've used - and while I'm sure there are much better units available - for the price - and for what they bring to the party, they are pretty hard to beat.
