First I've assembled headphones with some noname chinese headband. Cups I've made from aluminium. And with all that things I came into very friendly (at least to me ;) ) audiophile store that specializes in headphones.
Several people made listening tests of almost all available planar top headphones (oppo pm-1, Hifiman he-1000, audeze he-4) and dynamic top - Hifiman Hd-800.
That's me with my odd-job on head
That's again me, with perplexity on face why Aydeze he-4 costs so much?
I was encouraged with achieved and what is more important I was encouraged with reviews of other people.
What were the major bonuses in my headphones in comparison with planar top:
1. Overwhelming dynamics. It was like a big speaker with 15'' woofer vs bookshelf. Both can have 40 hz -3 db but you always clearly hear what is effortless reproduction of musiс and what is not.
2. Higher detailing in comparison to audeze, same level with He-1000.
Crooked tonal balance (headphones were almost without damping). That's a lot work to do.
After that test I relized that I NEED to build good headphones cause I'm absolutely not impressed by top headphones (especially when I read price tag).
p.s. I'm new to head-fi, yet not new in hi-fi. Never owned good portative system, but have an expereince in speaker building. Why not to build smth new?
