Summary: When I purchased my AKG K550, I was in the market for a closed-back headphone that gave me the best open-back sound while containing the noise so I could use them in a dorm room. The AKG K550 does that and much more.
After a few days of pink noise break in and heavy music listening, they really showed their true high-performance colors.
Pros: Balanced response, Versatile, Closed-back with an open sound, Build quality
Cons: Lack-luster with classical, ears touch drivers, take a while to break in, lose some personality with time
Summary: This headphone has a great neutral sound but I can see many people finding the bass a bit too lean yet not light. This can be due to poor seal which as mentioned earlier is a bit tough to get for some. I personally did find the bass very good however there are times where I feel it’s a bit lacking. But even with the perfect seal, people who are used to big bass and stuff may find this headphone a bit light in the bass.
With a good seal, I think the bass is very good.
Pros: Looks sturdy, bass is tight and midrange is lovely
Cons: Hard to get a good seal. A bit-lean sounding. Treble is a bit odd but still good
Summary: My last set of cans have all been Sennheiser's, (except a pair of Shure SRH550's which were very thin and uncomfortable). Sennheiser Momentum's were top of my list next to the HD598's.
My music tastes are very vast, but commercial, varying from Boyz II Men, Bruno Mars, to Bon Jovi, Kings of Leon, to Biggie and Jay Z.
Pros: Great for R'n'B and Hip Hop.
Cons: Top end can be a tad harsh, fit isn't perfect.
Summary: I am completely new to this forums and headphones; and not an audiophile at all. But I truly enjoy listing to good quality music.
I was looking for very very long time, scanning forums and all over internet trying to find the best headphones to start enjoying music with better quality.
I never tried any of the other headphones so I wont be making comparisons; but IMO this are great headphones to start with, I am very happy.
Pros: sharp looking, perfect bass for my taste, comfortable,
Cons: no detachable cord, long very long cord, maybe a bit too much treble
Summary: Along with the summary below, I have posted a Youtube video review of the K550. If you like the video, check out my channel for more reviews :)
The AKG K550 has excellent build quality, with a great fit and finish and a solid, durable feel to the materials. The earpads are very large and may not fit everybody's head; despite being very comfortable and supple the earpads are sensitive to seal and small changes to positioning will affect the already...
Pros: Comfortable, spacious open sound, great build quality
Cons: Very sensitive to seal, overall lean sound, somewhat raw treble, slightly heavy
Summary: Comparison Review: ATH-A9X, ATH-A900X, AKG K550
I have decided to update this review, not only because I've spent some more time with both the K550 and the A900X, but because I found frequency response measurements for both of them on Golden Ears. I know not everyone likes the way they measure, but since there are no professional reviews of A900X other than on DigitalVersus, and since you shouldn't compare measurements taken by different websites/reviewers, I...
Pros: Linear, smooth bass with great extension. Manages to sound fairly neutral while still maintaining good musicality.
Cons: Multiple issues in treble region. Mids are thin and lack body or presence.
Summary: Very comfortable and easy to wear for extended periods. The seal is good, if not tight--but I attribute part of the comfort to it not being too tight. Plus, the phones can be swiveled for a better fit (a feature I really like in headphones), which I sometimes have to do when I put them on. Ear pads are very big in diameter. I have a big head but small ears, so these covered my ears with plenty of room to spare.
