My taste varies wildly, from D&B to Rock to Hip Hop to classical. An amp isn't something I could afford and I had yet to be impressed with a pair of headphones across the entire range of my taste that are closed back and work with my laptop/iphone/work computer on the go. These fit what I was after exactly. I had tried momentums previously and thought they felt too closed in on my head and a little too boomy for all types of music. I also tried the UE6000s and thought they were very disappointing (NC off and amped) they also felt so cramped. I come from normally only wearing IEMs and in my opinion they gave me nothing over the Shure SE535s I normally wear all the time.
With these I'm doing that thing where I'm re listening to my entire collection again. In regard to the 'improved bass', there is definitely a good low end, but it's not bass-head heavy at all and only seems to be there when it should be and suits i.e Hip Hop has a nice thump without making me want to instantly take them off my head. I imagine it's not heavy enough for 'bass heads' but I can't understand how anyone would want any more, they sound well balanced to my ears.
For me, these fit my broad tastes perfectly and seem to do justice to everything. Sitting here with a big fat grin on my face after being disappointed a couple of times before. I was expecting the same this time and it's a world apart.
