Ok so im somewhat new to audio, my brother has been into it for many years. I go to him for advise on what i should get but sometimes he dosnt understand what it really is i want. I am willing to spend up to $600 on headphones for Classical music, and Opera. My brother is urging me to get Senheiser HD 650, he also told me to get those because i told him $400. I totaly see why just about anyone would buy hd650's. I on the other hand wouldnt, I have read a number of reviews saying how their sound is amazing, BUT the build quality isnt there. I like to have my headphones for years and years. I have had a pair of Beyerdynamic MMX300's for almost 3 years now. They still look new, and there is no way they will ever fall apart. but now back to what i want.
Great sound for classical and opera
sounds even better through amp, dac, pre-amp, ext...
good build quality
good padding, not just around ears but headband as well
cup padding cant be leather, if are id like to be able to buy different cup padding
as little plastic as possible (not really a big deal, but would be nice)
i do not care about weight
So thats mostly what i want in my headphones. so really there are just 2 headphones im avoiding because a number of reviews say build is bad or they can start to just get uncomfortable. thats the Sennheiser HD650's, and the HIFiMan HE-400. reason for the he400 is the headband. one other thing is i would consider paying even another 100-150. just to give a little bigger price area. i dont know if build quality goes up with price or if its just sound gets better and better. but i guess ill find out.
