I'm not even sure how they come up with those frequency ranges. Grado, for example, claims the RS1 goes down to 12 Hz, but it's rolled off nearly 25 dB by then!
Picking on Grado? Can I join?
SR60i, SR80i, SR125i: 20-20khz
SR225i, with the mere addition of UHPLC copper voice coil wire, nets you: 20-22khz
All are within like a couple of db in freq. response.
Still love the Grado sound and the value of the lower end models. Still chuckle at the freq. range marketing.
Forget these unambitious wimps, I'm gonna design a headphone that can do DC-1mhz to match the customer's 10,000$ amp.
