check out the akg k181dj. it's much better built and sounds better. with some simple changes it is reported to turn these into surprisingly high performing cans (http://www.head-fi.org/t/323653/akg-k181dj-review#post_4183439
Hifiman HE-5LE. I never found them comfortable for my head as the cups are installed so low down on the band that the tops of the ear pads would push down on the tops of my ears, no matter how high up I pushed the cups up the rods. I had to bend the headband into a straight horizontal line to raise them up enough to be comfortable (this headband design is the reason i won’t try out the HE-500 even though I figure I would love the sound)
That's essentially the issue with the HE-400s, the HE-500s and I'm assuming the HE-300s, too. They have the same fit, measurements, etc. People with a smaller distance from the top of their head to their ears, will have a feeling of the HifiMAN headphones fitting this way. By no means, does it indicate the individual has any less brain mass by having a smaller head. However, I'd think that HifiMAN would listen to some of these comments and make the necessary manufacturing adjustments. Thus, I can only think that in the country where they are produced, the heads are possibly even smaller - and, drowning the tester with the cups tugging down. My last sentence wasn't meant to be racial, or single out any special racial group either, but thought it was relevant in my comparison.
perhaps putting some padding on the underside of the headband would be a simple, albeit stop gap, solution to this problem?
