You know, I would pay $50 for a quality ear bud. I don't need the latest whizz-bang technology either. Since I can get a good seal by simply pushing lightly with my fingers, I'll bet someone could come up with a decent semi-seal on the cheap. A partial seal would help achieve the "rumble" when needed. I don't need the full seal of a stiff finger push on the body, as I'm not a basshead. I do appreciate the full range when appropriate,but attack energy, rolloff, etc are all important. I have 8 or more IEMs that can easily provide decent midrange and pretty good treble, all for $50 or less. Seems like the $50 audiophile ear bud is just around the corner. And for you early adopters, a shout out would be appreciated.
