Pros: Highs, mids (if your a mid's person)
Cons: Bass, high mids
I purchased these headphones for my birthday of this year to replace my Logitech G930 headset. I've never had an "audiophile" or very high quality pair of headphones, but have heard very great things about them. I am a person who makes sure my music is in FLAC or other lossless (Or from original CD to lossless) so this isn't your average person who listens to MP3's on their Ipod.
To start when I got the headphones, the design was terrible. Looked tiny like it would break and actually DID break on the second day of usage. The left connector to the cup broke off, I do not have a big head and I never mistreated them, but it's most likely manufacture defect. The next thing I noticed was the comfort, they use foam pads that are itchy to my ears, and their not very sensitive. It can really get on your nerves and you have to take them off for a while after a couple hours of music listening because of their ear irritating fatigue.
But the most important aspect of this is the sound. When first used, there was no bass. NONE, not a single bit of bass could be felt from these headphones, my G930's surpass these Grado's 10x over in bass production, which I find quite sad. Although I do have to praise the reproduction of high frequencies. From listening to a couple high-string heavy songs from Red and a couple of solo/chorus high singings it seem's VERY nice to listen to. It will make you be able to feel some of the highs, if you know what I mean.
Lastly, the mid's we're turned up way too high on these. I don't have an equalizer running from my motherboard audio source (Realtek audio stuff) and neither in any applications, so this is pure headphones. The mid drowns out any sort of highs and makes it sound quite muddy, not defined. And no matter how I equalized, it would sound bad.
The combination of the no bass, oversized mids and headphones breaking pretty much sealed the deal for me to return them to amazon along with my FiiO E9 (And 6.3 to 3.5MM jack) that I bought along side the headphones. (Not even the FiiO E9's Bass boost would make the bass any better!)
So right now i'm stuck with my G930 headset, that I have no major gripe about since I got the software to work and have the headphones equalized to my liking, and they are closed headphones, so I don't have to worry about waking anybody up anytime soon (And are wireless!). Grado's are not my audio reproduction style, although they might be for you.
So my journey for my perfect headphones moves on!
