A990Z arrived and I am pleased. I am currently listening to Florence game OST by Kevin Penkin. The A990Z has more low end than I expected, but has a nice warmth to it. I like the treble is mellowed compared to some other closed headphones like SRH840, K553, MSR7 that I owned. These A990Z I appreciate were made for music appreciation, these are not studio headphones or tried to be as flat as a European model. These are headphones I can definitely appreciate music with and get lost in the music. These are a keeper. K553? Bye bye, A990Z are taking up your listening time.
Compared to K553
- Seal is more forgiving on the A990Z. These rest on my head comfortably and as the memory foam conforms to my head, good seal. The K553 I had to change pads and really bend the headband near the cups to get a decent seal.
- Sound Stage. This is where K553/K550 seem to get a lot of praise, closed with soundstage. Well I have to say the A990Z is better. It's got a more airy sound that surround me with wonderful sound.
- Imaging, as expected, K553 is superior. Overall K553 is the more detailed headphone. But then it is marketed as a pro studio closed headphone. So it would make sense it would have superior imaging and detail. A990Z is no slouch though.
- Bass. A990Z yes. Just because of better seal, and I do think A990Z has more oomph. I think the bass from EDM like Hybrid - Morning SciFi - True to Form sounds much better on A990Z. But for rock K553 has more detailed bass from kick drums.
- Mids. K553 has more detailed and better mids. But right now, I enjoy A990Z mids more.
- Treble, same, K553, but I enjoy the slight roll off with A990Z.
- Overall the K553 is technically superior, but A990Z is more enjoyable. The mids sweeter, the bass more weight, more airy expansive sound. A990Z is good enough, I don't feel the urge to hear the A1000Z.
Also green is my favorite color, that's a plus.
