I've had an e250r for over a year now.  A couple months back, I started running into problems with the sound cutting out in one earbud.  I figured it was just the cheap earbuds that came with it so I replaced them with a better set only to have the problem still occur.  In troubleshooting the issue, I've found that this happens with specific MP3s at exactly the same spot in the song.  In some of the songs, the sound will be completely cut out only to fizzle back in, starting with lots of static and eventually returning to normal.  Some songs the sound stays completely out but as soon as the next track plays, it is back to normal.

Anyone else experience this issue?  I'm thinking it's something in the MP3, perhaps the bit rate or something.  I'm thinking I may re-encode the problem tracks to see if this corrects it but I'd like to hear if anyone else has experienced this.  Thanks.
