Pros: Portability and sound.
Cons: No padding on headband.
I bought these for portable everyday use, and I can't say enough good things about them. They are perfect. The sound is amazing. I have Beyerdynamic DT770's and these sound like small versions of those. These have very punchy bass and nice mid and treble, with beautiful sound stage. All of this coming out of a small headphone. All the specs are good, and I couldn't believe these were 32ohm. Awesome!
They are "on ear" but they nearly cover my ears, which is great. I didn't want really small on ear phones.
The cord is really short, which is great. No more having to deal with million foot long cords bunched into my pocket all day.
They fold DJ-style, which is beautiful. When around my neck I can fold them in this way (flip the earcups so they are facing out) and I don't even know they are there.
They are SO light. So light in fact that I don't really feel them while I wear them, but after a couple hours I may adjust them on my head as I may feel the headband a bit, as it doesn't have padding. But this is really no big deal. I thought to put 3M foam strip adhesive padding under the haedband, but really they are so light there is no need. Other regular full sive DJ headphones (even my Beyers) hurt the top of my head ALLOT more.
Build quality looks beautiful. These don't look like the leather earcups will be coming apart anytime soon, if ever.
If you are looking for headphones to wear all day, look cool, and actually sound as good as $300+ headphones, these are for you.
