Summary: When I first got these the sound was rather tinny, but over the initial 50 hours they really, really opened up and grew to have a very natural sound. I have them paired with an HRT MS2+ and a Schiit Asgard, which is apparently a good match for Grados. That sound became more warm and round when I switched out the normal pads for quarter-cut softies.
Pros: Bright, lively, good separation of ranges.
Cons: Uncomfortable pads and headband, design flaw on cup holder, heavy.
Summary: Was not happy with the 325i. Very bright sounding through most of my musical catalog. Sounded very detailed at low volume. Bass response was surprisingly deep. Very forward sound signature. Good headphone for metal and very fast. Comfort is terrible. Only torrerable at low volumes for my ears, even tamming with soft tubes.
Pros: detailed highs, people ask questions while wearing
Summary: The harsh brightness also removes some of the depth and dimensional space you'd expect from Grado headphones. I'm sending 'em back and buying the reference 2 for 499. If those are similar fatiguing and unwearable for more than an hour, then it's back to my BeyerDynamic 880's for me.
Pros: very detailed clear sound
Cons: harsh and bright. if you mix with these, you'll think your music sounds grating.
Summary: I have owned a pair of Grado SR325i's for about a month now. I use them to listen to a variety of sources including an iPhone and a high end audio system. Acoustically, they are pretty good, but not quite as good as i'd expected from reading some reviews. On the positive side, they present a very revealing and clean sound that is usually very pleasant to listen too. I feel they are a little bass light though and occasionally sound a little too crisp for comfort.
Summary: This model has been replaced by the SR 325is, which is silver in colour whereas these older ones are gold. I am rating these as 3 stars because Amazon won't let me post this review without a rating, I do not own these headphones, nor have I heard them. I do however own the newer model. I would recommend to anyone considering Grado headphones to give them an extended listen to find out if the headband comfortable for you and if the construction of them is to your taste.
Summary: I bought these and a pair of HD650's for comparison on my two gaming PC's which have dedicated Xonar D2X sound cards and on my Sony FA30ES amp. The first thing which struck me is how cheap the build quality is on these cans. I mean, the ear pads are cheap foam material, the black plastic bits on the ear piece seen in the picture are badly moulded and the whole thing just feels tacky.
Summary: Wonderfull detail, BUT too sibilant for my liking and for the price. I have been using my set for about year and it is as hisssssssy now as when it came. The costly addition of Graham Slee Novo headphone amp did not improve the problem in any way. The set construction feels a little primitive too. The cans twist around freely and its too easy to get the cables,(enclosed in a cumbersome loose sleeve) twisted "out of place" with minimal use.
Summary: I've just received my first pair of Grado's today and thought I would go for the SR225i's. I have been using the Ultrasone DJ1's for the past 12 months and have grown used to the excellent sound stage provided by the S-Logic system. For listening to music in general these cans were great, but for TV they were too sterile (suited mainly for DJ's) so I decided to seek a replacement. Hence my Grado purchase.
Summary: Dieser Kopfhörer ist ganz sicher sein Geld wert. Der Klang hält auch mit dem von deutlich teureren Hörern mit. Die Auflösung ist sehr gut, verglichen mit einem guten Elektrostaten sicher nicht gleichwertig, dafür klingt der Grado aber teilweise druckvoller und dynamischer, was dann auch wieder realistischer sein kann (und auch sehr viel Spaß macht). Um so bedauerlicher ist für mich der Tragekomfort.
