How much darker? I love my SRH940 and the UE900 seems similar to that headphone. But if the W4 is only a bit darker they would be maybe more like my SRH1440 which I also love
. Also which IEM has the most energy? Sorry for all the questions but I would have to return these and then order the W4 online so have to do some due diligence here...
A lot changes as the pinhole blocks :p For all intensive purposes, I'm assuming "energy" normally correlates to a bump in the upper midrange to lower treble (maybe also midrange). So before the pinhole fills, the W4 is only a little darker than the UE 900. The W4 still has more energy in the upper mids and lower treble. After the pinhole fills, the W4 becomes a little more darker, but the 900s gain a lot more energy.
