Summary: I began writing my review and realized it was almost identical to the excellent review of VanD above. I echo his comments regarding the great sound quality of the Grado GS1000i's as well as the outstanding Crutchfield customer service. I own the Grado RS-1i's, which are also fantastic headphones (I became a Grado-phile after comparing the RS-1i to my Sennheiser HD-650's; the Senn's sounded muffled compared to the RS-1i's, and I had been a die-hard Senn-ophile for years).
Pros: That crystal clear Grado house sound. Very comfortable over long periods.
Cons: Needs a little more bass No cushioning on head strap (a standard Grado flaw) No case Expensive
Summary: First, let me say that my experience with Crutchfield.com was beyond satisfactory; it was among the best online shopping experiences I've ever had. Customer service was attentive and responsive, shipping was super fast, and I was given a full satisfaction guarantee. Crutchfield's reputaton is well deserved. Now to these magnificent headphones. My first experience with Grados was with the SR325is.
Pros: That spectacular sound. Comfortable enough to wear for long periods, unlike the SR series Grado cans.
Summary: If there ever was a niche product, audiophile headphones are it. Purchased these based on reviews I read on the internet. I was not able to find a set locally to listen to. I had owned a Grado headphone amp for several years and was impressed by its quality and performance so I was already sold on Grado. This plus the fact that these headphones are designed to work with the amp I already owned made the choice easier.
Pros: Comfort, performance and retro look along with legendary Grado quality.
Summary: If you're willing to spend a lot on headphones, you'll hopefully have already put some thought into what sets you should be looking at. There's no doubting the GS1000i are one of the best, with superb levels of detail on-hand and far greater comfort than you get with the more expensive PS1000 pair. A keen ear and a quiet listening environment are key to getting the most out of these headphones, but if you have those vital ingredients and a love of great sound.
5 Stars for Sound Quality but only 3 for build quality
5 February 2014
Summary: I am reviewing these headphones after buying them from a Grado UK dealer near Peterborough for £997 rather than the £1200 they are currently being sold for on Amazon. I have come to the GS1000i's via the 80i's and then the superb Philips Fidelio X1/00's. I now live in a flat so can no longer enjoy my music through full size speakers late into the night as I used to.
Summary: Not exactly being an audiophile, I was initially interested in these headphones as I wanted something sturdy, long-lasting and first class in the sound department as these were going to be a one-off purchase for me. I bought these along with a good headphone amplifier (I opted for the Graham Slee Novo) and was truly blown away by the results.
