When I unpacked them the weight of them threw me at once, I thought this is not going to bode well... But they are very comfortable with the plush headband and ear pads, the pads could be a little bigger for me and they do get sweaty, so some velour's might be a nice option or it will destroy the sound completely...
No Bright Treble! So I love them right out of the box, bass quality is on par with if not a bit deeper than the HFI-780's, the HFI-780 with HM5 pads beat them in comfort but the HM9's might just be a better all rounder than the 'Sones.
I was going to try the HM5's but after reading and comparing them to the FA-003 Ti's, I'd rather have the Fischer's based on the look and build quality, I like the metal yokes and those plush pads are real leather.
So I am glad I chose the HM9's to review, I feel they will work out very nicely!
Yes, the weight I have concerns about younger teenagers, in particular females holding the weight of HM9 over many hours. The pads are very much like XB500's if you've ever worn them but smaller in diameter. Considering it's Winter here I can't test for sweat and heat build up due to lack of air under your ear but it should be ok.
I really love the HM9 for its appearance, almost futuristic or alien type approach and believe that's what the headphone is a large percentage about. Grabbing the mainstream.
