I am currently using 8 a Heir Audio custom IEMs.
I am planning to get HD800 and D7000 or D5000
But I am also considering to get one more sub-headphone.
I prefer big sound-stage, strong bass, light weight.
He-300 is 270g and ma900 195g. Doesn't that matter with weight here.
Which one has bigger sound stage and stronger bass? ( also balanced sounds as well).
They are both open headphoens. ( If He-300 is better, I would also consider to get He-400 or 500, but too heavy to go for them)
