It's NOT M80 sound, these are for serious bassheads. It says on their Facebook that the LP2 has a different sound signature compared to M80 too.
I wonder what headphone those 2 grey curves on the graph corresponds to, the $349 headphone which I suppose is the darker grey curve I think looks suspiciously much like
D2000's curve. I wonder if the light grey curve is LP1's curve though... if that's the case the LP2 would have better bass extension than LP1 (amazingly good, beating or about par on XB500) and has a little more balanced highs and mids.
It even looks possibly like being TOO bassy, I mean if we put 100dB as the normalized / zero level the bass stretches as a 15dB boost (115dB) at ~15Hz to ~50Hz but from 60 ~ 170Hz we're talking about like 3dB higher boost, ie ~18dB+ boost (118dB!). Man these will punch like mad, possibly too much even for a serious basshead. From the graph IF it's accurate this could be the bassiest measured headphone so far... well to be honest it's difficult to say since XB500 got a lot more recessed highs and a huge dip in the upper mids at 3.5kHz so that might even up the bass boost difference quite a bit, but yea at least they will be bassy that's for sure... it will be interesting to find out and compare especially with XB500 since they got somewhat similar curve but LP2 looks to have more balanced mids/highs.
