I must say that I ended up selling my MTW4. At first, they seemed to be an upgrade regarding more bass definition, altough still a bit congested sounded like MTW3. When I listened to them more and more, I find guitars peaks to be a bit to edgy and bass is thunderous and much louder than other parts.
I tried to reduce the bass amount with sound peraonalization setting it to the lowest point, but surprisingly it is still thunderous and persistent to the point I cannot listen to music that way. As an owner of also MTW3, I would say that MTW3 is closer to Sennsound than MTW4 which is much more mainstream no matter how much MTW3 is V shaped.
The bass on MTW4 is just way too much for my ears and I like bass in overall.
I didn’t want nor expected this scenario as I’ve been excited about version 4, but it is how it is. Maybe version 4 is just for very young generations and not for older guy like me who listen to old rock, blues and jazz.
Tried Sony XM5 in the meantime, but they are absolutely dire with their mechanical, edgy and overtightened sound.
Back on MTW3 and music is back, but would like something with better separation, definition and crispness, but made in a right way and without just sharpening the edges.
