Query: Very tinny with no bass!

I used to be a fan of the Koss PLUG. I had two pair which I wore everywhere. They delivered great bass with a full range of sound. Isolation was good. But a cord of one got caught in my door and destroyed one earbud. So I decided I would purchase another pair. Well the new pair does not have the same bass response at all. It also does not have the hocked earjack but a staight connector. This new one is not convenient since it is easily kinked. But the sound change was dramatic. This was a real disappointment. I really loved their old design.
