I've had good experience with the JBL lineup... I'm on the largest (boombox), and I find the quality acceptable (I don't find the quality of most audio products acceptable). The convenience OTOH is phenomenal -- it comes with me biking, kayaking, (it's submergible) and camping to charge devices and play music, and the charge can last >week. I can only remember it dying on me 2 times in the months I've owned it, and I rarely charge it. One consideration is that it's much too large for backpacking or hiking.
I wouldn't necessarily classify myself as an audiophile, though I do care more about accuracy of reproduction than most I meet.
