That's pretty much the usual reaction after hearing accurate sounding headphones for the first time.
Yeah, right... sounding like a $10 radio is "hearing accurate sounding headphones for the first time"...
They don't reproduce the music instruments, the recordings are right, they are bad.
There's nothing good from them being open, except easier to manufacture.
They don't fold..? Why the hell would I want my hi-fi headphones to fold? So they take less space on the table next to my preferred audio source, a DAC and a headphone amplifier?
Does folding make them sound worse?
No?
Then I expect them to fold.
Grado is a high end headphone company, just like Sennheiser or AKG. Their target market is pretty much disjunct with Beats' target market.
Audiophile market is a market for fools.
Source: I'm an Electrical Engineer. They sell bad stuff for crazy (>1000%) high margins, and the worse, since they can't make nice modern things, they market old stuff as "better" (like turntables).
Want a good pair of professional headphones? Get a Beyerdynamic DT 1770 Pro, those are the best headphones in the world, confort and sound quality, want cheaper? DT 770 Pro. Then you'll realize what a good pair of headphones is.
