Tinny Sound--No Bass

Help! My Clip sounds very tinny.

I swapped the ear buds with known good ones (JVC), but it made no difference. The same earbuds work fine on other comparable MP3 players from other manufacturers. That leads me to believe that I should not have to modify or swap the earbud foam.

I tried all the EQ settings, including custom, with the bass turned up and the treble turned down. Nothing resembling bass tones were to be found.


My MP3s were ripped directly from authentic CD source to MP3 format. That would have minimized any lossiness, plus, the same MP3 files sound fine when played from the PC. 

Short of returning the device to the store, what else can I try, please?

Would the firmware update have addressed this problem?
