This thread is so full of controversy, I just had to buy a pair.
Besides, the white version is just too sexy to pass up, don't you think?
So anyways, I received them two days ago. I got them used, but they have very little play time, something around 25 hours. After a careful but thorough cleaning, I put them on my head...
Wow, those are light! Compared to the Shure, those are feathers on your head.
The clamping force is close to not existent. Then the bumps under the head band started digging holes in my skull and the ear cushions (At this size, it would be more appropriate to call them pillows) made themselves felt on my bones. I just don't know what AKG thought when they designed those bumps under the head band. As for the cushions, they are not really hard. The issue is the sum of a few facts. First, the clamping is very light and Second, the contact area of the pads is huge. Put this together, and the pads don't "squish" on your head. They simply hold on to the angles of your bones. That said, they are still more comfortable than my Shure and I had no troubles wearing them for a few hours straight. With the Shure, I continuously have to resit them as the weight and the clamping force gets overbearing.
I listened to the Q701 directly trough my Audio-GD NFB-12. My first impression on the sound was that it was very distant, at least compared to the Shure. With the SRH-440, it's very obvious that you have a driver less than an inch from your ear. Vocals sound like the singer is speaking directly in your ear. All the sounds come from inside your head. It's actually worse than sitting in the middle of the stage. When I put the Q701 on, I feel more like I'm sitting a few rows back in the crowd. It sounds more like I'm listening to speakers than headphones. I must admit though that this sound left me underwhelmed at the Q701. I don't hear anything special about them. So far, I found them more "laid back" than my Shure. Since those are my first open cans, can I conclude that what I hear is a normal open headphone sound?
I listened to Electronic, Rock and Metal so far. I can see how so many people claim the Q701 are bass light. Even my SRH-440 has better bass than them... which I totally didn't expect when I looked at the FR charts. Kick drum sounds SO much different between those to cans. Q701: "tud tud". SRH-440: "bang bang". Weird. From the many live kick drums I heard, I'd say that the Shure has a more realistic representation of them. I'll have to listen to more albums and do so A/B testing before I conclude on that though.
I haven't had my NFB-12 for a while either, and I'm still testing the different filters. So far, I found that the filters with treble roll off sound smoother with the Q701. I'll be listening to them more and post my findings later. I watched a few movie trailers and was quite impressed. They pull out impressive sub-bass. I can't wait to watch a movie with those.
