My headphone amp has a dB scale that I can adjust from 0 to -infinity and while with the specific attached headphones it's very loud at 0, it's not soo insanely loud that I consider it complete madness. Tolerable for short periods of time with regular music that is. From that, I assume it's probably somewhere between 110 and 120 dBSPL for 0 dBFS (*). (*) dB Full Scale, with 0 being the maximum. Good CDs are mastered at around (max) -12 dbFS average although unfortunately since 2000 or so the music industry has completely lost their senses and you nowadays find quite a few CDs at as bad as -6 dBFS average meaning you have exactly one bit left for your entire dynamic range, which you then have to range-compress to fit it in! Google "Loudness War" and write to your senator(s)... those idiots are destroying modern music.
