HD-669 : Good for the money, but there's better options for not much more money

I wanted a pair of beater headphones for people tracking that I wasn't too worried about, so I grabbed these.

First off, the build quality seems pretty good. I haven't had them long, but for the most part they seem reasonably solid.

They came with 2 cables (long and short) which is nice, but the short one will never leave the box. There's also a clip that holds the cable in place - good for someone not moving, bad if someone steps on a cable, as rather than the cable detaching, you throw your cans on the floor.

Adjusting the size is a nightmare - incredibly stiff,with no external markings to make it clear when both sides are equal. Better tight than loose though I guess. Also, they have these weird separate foam blocks sitting on your head - I've never used something like that before, and I'm not a fan. They're at an odd angle, it feels weird, and seem kinda flimsy. Once everything is set and they're on your head, they're fine though - tight but not too tight, reasonably comfortable for a couple of hours.

Sound is where they win over though. At first they felt bass-light, but actually it's just not hyped like in many headphones. The bass goes pretty low, but it's never over-powering, which I like, and it's reasonably tight. The highs take a while to burn in - they were crazy harsh at first, but after a day of running loud white noise through them it's much better, and getting mellower all the time. It feels like they go higher than most of the other headphones I own - they aren't top heavy, but I feel like there's something happening right at the top I don't usually hear. Mid range is detailed and clear. Over all, they seem pretty well balanced - pretty unexciting for listening to music on, but probably flat enough to use as a reference for mixing. The lack of hype should mean they won't be too fatiguing for long tracking sessions either (assuming the high end continues to soften).

Honestly, at this price I wasn't expecting much - but they sound way better than I thought they would, and the feel more solid than I expected. I can put up with the weird headband blocks and the crappy adjustment when the sound is this solid. For a bit more money, there are definitely better options, and I'd always go there first. If you've already got a bunch of headphones and just want another flavour, these are a decent bet though.
