my sony mdr 700's range is 5hz-30khz. you can get them for 100-150 deending on where you get them.
Very accurate headphones and they can get so loud the bass actually hurt my ear drums

. Some people say they are bass heavy but IMO they accurately produce sounds in all ranges. Booming lows, Solid mids, crisp clear highs.
One of the best things about my PC setup is those headphones. Combine with an audigy and youll see what i mean
