These are not at all that bass-y. Not nearly as much as a dedicated bass tuned dynamic at least. While the bass is there, the range is more attuned upward, towards the higher pitches. The mids are there, but are more for vocals, strings and some(but not a lot of) bass. Readings on a machine are one thing, but actually listening is something else entirely. I never use the infernal things because of that....I have over 90 hours and counting on these and all I told you about classical being good here is still true. Honestly, try these out for yourself because it's ultimately you who matters most.

More precisely: the major emphasis focusses on mid-bass with about 6 to 8 dB. Sub bass and upper bass have got less level but are also obviously emphasised.
I hate that.
