Is there a lottery with headphone drivers, similar to processor chips or monitor panels, where every one is a little different? I had two pairs of AD900x's. I swear the new one I got has less low-end than the last one. Also, this might explain why some people describe things about certain...

I had the AD700 and preferred it too, even over the K712. Not worth the price jump at all, so I got the AD900x instead.

If it matters, I thought the AD1000 had a bit harsher highs than the AD900x.

The imaging is good enough and much more immersive because it's in a larger space. You should be able to judge the distance of sounds better on it too because of this. The AD line is known for forward mids, which I think can be a plus for gaming.

I've listened to a lot of harsh sounding headphones. The AD900x isn't one of them, and I greatly preferred it over the HD598 and SHP9500 for the soundstage and mids. Good comfort too. I even think there was more bass, but I'm not sure, and they're all bass light anyways. If I had to pick one...

AD1000 has a more forward sound and no angled drivers. It has cleaner treble and more clarity overall, and better imaging but in a smaller soundstage.

I've personally compared the HD650 with most well-known open-back headphones $500 and under. This includes the HD600, HE400i, R70x, AD1000x, Fidelio X2, K712, SRH1840, HD700, and DT880/DT990. Am I crazy to still prefer the HD650 over all those? Please tell me I'm not the only one.   It has a...

They're similar but there are some differences. The AD900x is still a bass-lite headphone, but it has a bit more bass than the anemic AD700, and you can actually feel that it's there. The highs are less "smooth" and sound more like standard treble which helps you hear details better. The mids...

I have an AD900x on the way and will gladly compare it with my AD700 if anyone is interested.

Thanks! I have an AD900x on the way, and I'll be sure to compare it with my AD700.

I already have a headphone for music though, the HD650. So purely for things like gaming, the AD700x would be superior? Or do you think the AD900x would be more immersive with it's extra bass?

Is the HD598 different enough from the HD650 to use it as a gaming headphone when I'm not using the HD650 for music? Or would I be better off with something like the AD900x? For larger soundstage and positioning.

Quote:   So they have somewhat similar soundstage, thanks for clarifying that. One last thing, how would the HD650 compare to the DT880 for things like rock and electronic music? Would the midbass on the HD650 help them win with those genres?

Can someone who has owned both the HD650 and DT880 tell me how the soundstage compares? Thanks.

What would be the HiFiMan equivalent of the HD650? The HE500?
