I just got in a set of Brainwavz HM9 Full Sized Headphones in a few days ago for evaluation I've been listening to them for over 25 hours now, with few breaks in between to judge long wearing comfort, and with several different type of music. I can state right off that these are, thankfully, nothing like Beats...a problem with lots of bass emphasized headphones. The signature definitely edges towards the bottom end, but in a good way, not an over powering way. There is a full soundstage at play here, with some really nice separation, and no muddiness at all.
The bass end is rich and full, with many layers to it, easily separating the Bass from a guitar from a Bass drum. The high end is also well represented, with a full range to it, but zero sibilance rearing it's ugly head. The mid range is the only thing I'm feeling could be better represented here, it's not missing, but it isn't as center stage as the rest of the signature. This isn't "V" shaped, not in the least, just not as strong as a, say, neutral set would have been. A little bit of EQ fiddling fixed this right up, though, so it really isn't a problem that cant be fixed. All told, this has a full, rich great sounding signature, one that would fit right in with those looking for a strong soundstage for many different types of music, especially modern pop.
I like the three sets of cables that came with the HM9's. The two main cables are flat wired and are of differing lengths, one shorter one for travel, and another much longer one for home use. They seem sturdy and plug into the left ear cup(this is a single wire solution, not a dual as the HM5's were, I like that, less clutter). Also included is a rounded shorter length mobile mic'd cable. I tested it with my new Nokia 521 Windows 8 phone and it seemed to be recognized well, and a few phone calls revealed it to work great, with both good sound quality outgoing and incoming, nice. I could not answer a call, though, but I could terminate it. Always gonna be a compromise here with these mic'd solutions. I'll try it on my older Android phone later on and report back on its effectiveness.(EDIT: I tried it with my Samsung Galaxy S2 and had no problems with it at all. All worked as it should). As for fit, the HM9's have big, fluffy, comfortable memory foam ear pads that sit ON the ear mostly, but have conformed to sit partially over my ear(the top part) after around 10 hours of use. It has little clamping force...a good and a bad thing. Good for comfort, bad for staying put on your head with a lot of movement, so these wouldn't be my first choice in the gym, but they do clamp enough to stay put with normal activities like walking and sudden head movements. Build quality is above average here, with strong construction and really high end materials used, like aluminium and strong, but light, plastic. I also like the little touches, like a little bit of foam on the inside edge at the top of the ear cup to prevent it from getting damaged by the metal(see pic), nice. I like the overall design as a whole, with a modern look, it looks better than I thought it would on my head. And thankfully it doesn't try to emulate Beats, too many trying to do that already. The folding aspect is also a nice one, as I travel a lot and it makes the included case more compact for easy packing.
I used my Rockboxed Sansa Clip+ as well as my Nokia 521 Windows Phone for testing purposes, with no external amplification.
I will update this as I go along, and welcome any comments :) I may do a video review of these, if interested let me know and I'll post it here.
