First pair I bought got stolen outta my car, somebody smashed my window and took my bag that held it :(Anyway, first pair sounded great.I bought another pair, there was an extremely disappointing crackle in one of the headphones from a low frequency.  This made me extremely annoyed/angry/disappointed.  I cannot stand bad crap, and I hate to give bad product reviews. But I had to send it back and now I will look for a different company brand, probably for the rest of my life. 

Question: How is the quality of the bass?
