I've been searching for my "end game" pair of portable headphones and have come across story after story about build quality problems among the top models. In particular I'm talking about the NAD HP 50s and the Focal Spirit Professionals, which generally seem to be regarded as the two best sounding portables.
I've tried a number of headphones lately myself - the Thinksound on1s, the Onkyo EF300s, the Soundmagic HP100s, the AKG545s and the Mikros 90s. The only pair that comes close to my $50 Koss DJ100s in build quality are the Soundmagics.
Why? Do manufactures know that us audiophiles will pay for sound above all else and therefore skimp on construction quality?
Personally, I'd be much more likely to part with $300+ on headphones if I know they had a good chance of lasting me 5 years under regular use.
Which elite sounding portable headphone does have the best construction?
