Summary: The sound on these is absolutely stunning directly through the headphone jack. It may or may not benifit from an amp, all I know is that I have spent about 30-40 hours listening to Pink Floyd like a complete fool. Over, And over again, So I can tell you these headphones sound really, really, good. Initially, the treble was a bit harsh but since I like listening to music at low to moderate levels the sibilance really is not to a (Headache-like) level.
Pros: The most open I have listened to, Energetic Fast Attacking, Mids, Detail,
Cons: Comfort, Treble response, sub-bass is lacking on some recordings
Summary: I had the pleasure of living in Toronto for 4 years and bought these at the excellent Bay Bloor Radio. BBR have a wall of headphones all fed by the same source, so I spent a few happy hours there on a quiet Monday night armed with a few favourite CDs.
I listened to AGK701s, a variety of Senns and all the Grados head to head. For me, the 325is (the Gold edition) were the best of the bunch, even versus the reference series models.
Pros: Phenomenal SQ, like no other headphones I have heard
Cons: For me personally, a bit heavy and uncomfortable in long listening sessions
Summary: These were my third pair of headphones, after the AT ES7 and Shure SE 530. I kept reading about how they had really hot treble, and sounded really unique and would be the opposite of the HD650( which would've been the logical upgrade from the 530 in terms of sound signature). Something about having something almost opposite sounding was really appealing
Once I finally got these, WOW! I almost thought they had too much bass!
Pros: Great treble, impactful, unique sounding bass, BEAUTIFUL mids, great construction and aesthetics, swivel cups
Cons: SOMETIMES can be uncomfortable, bass could go a little deeper at times
Summary: My first set of "premium" cans were the Grado SR80's, driven from an old classic iPod. As you can expect, I was blown away by the sound quality compared to those little white earbuds.
I've tried other headphones in the $200 range including AKG K271's, UE triple.fi's universal IEM, and my latest set, the Beyerdynamic DT990-600.
To my ears, all non-Grado phones lack a certain warmth in the mids.
Summary: After 4 years of regular use, my cables were looking a little rugged, the plastic cover over the cables that split to each ear were cracking at the Y splitter . I called Grado and they quoted me $45 (includes return shipping)for a new cable plus an additional $15 to upgrade to the newest 8 conductor UHPLC copper connecting cord.
Summary: Long story short, they're fantastic. I bought my headphones from a display/test setup at a Magnolia hi-fi, I didn't want to wait and I got a great discount on them. I'm sure the salesman still turned a profit of course. (I work retail, I have an idea of the markup levels.) They're comfortable to me, and I don't intend to own many other headphones.
Pros: Better than anything else for the money, well built
Cons: I now realize how many low quality recordings there are!
Summary: Hi everyone, Just wanted to give my two cents re: the Grado 325is!
I was on a head-fi poison hiatus for a while because I thought I'd already spent too much on this hobby by acquiring a high end IEM (JH16 Pro) and a good PMP (Cowon J3 - which I unfortunately lost). In the case of IEMs, I think I already achieved audio nirvana, but then this itch of wanting to try what full-sized cans could offer was always bothering me.
Pros: Musicality, Emotion, Heart and Soul
Cons: Great with SOME types of music and mediocre with others , HEAVY and hardly portable, wire management is a dilemma
Summary: Ok, this is my first review. However, I feel that my opinion matters as much as anyone elses. I'll start from the beginning. I have been creeping in here for quite a while and soaking up as much info as I can. I am not an audiophile, really just a person that enjoys music a lot and its a part of me. I decided a while back that I wanted to roll with Grado because the genre of music I prefer, old metal head with some punk and classic rock thrown in.
Summary: The Grado SR-225i was my first real pair of "audiophile" headphones and I loved them to death. In a foolish fit last month, I traded them away. After trader's regret set in I found a pair of goldie 325is that had been modded with detachable cables and screw fasteners to keep the headphones from sliding down.
Pros: Best sound and definitely worth upgrading from the 225is
Cons: slight slippage in the fit when I wear them for an extended period
