I don't like how they're built half-assedly and odds are you will encounter some sort of build deficiency somewhere along the line. I don't like how there's a special term for driver rattling that plagues Grado's exclusively. I don't like how the earcups are held by thin metal rods and as time passes these metal rods start sliding off because there's no more grip. I don't like how they don't sound that special.
I quite like Grados - I've had the SR60i / SR225 / SR325i / SR325is and GS1000, as well as Alessandro MS2 and MS2i
Couple of things though :
1) Cable design. Bloody awful. I *love* chunky cables, but I should not, for £300, be afraid of the earcups turning around too much and the cables splitting.
2) Overall build quality. Questionable - I've had a new pair of SR325i with tooling marks in the metal, and GS1000 with cracked wood on them.
3) Comfort. There is simply no excuse for the sandpaper-like bowls Grado use on some of their heavier bodied models (SR325/325i/325is and Alessandro MS2/i)
There is no excuse for a pair of £300 headphones being too uncomfortable to wear for more than 30 mins. I mean I tried bending the headband, which made them too loose to lay down with (and still sandpaper like on my ears!), and I tried all sorts of 'mods', but just gave up.
Which is a shame, because in all honesty I thought the sound out of them (the 325is in particular) was exactly what I was looking for, and even better that they didn't need amping - but what was the point where I was in pain using them?
If I had one word of advice for Grado, it would be that they - in all honesty - they've got the sound quality of their lineup sorted - now must come the time to work on comfort and build quality? Perhaps a bit more work on ear cushion material or designs, perhaps even drawing from DIY ideas here?
