Just bought a pair of Sakar Ultra Deejay Headphones (with super bass quality). They sound good plugged into my usb computer speakers, while turned up to the max, but I would like to swap them out for a better pair. Bass is really good. That's all. parts-express.com has speakers, but I dont know where to start. Any suggestions? These are the most comfortable speakers I have ever worn, I really would like to upgrade them
