I recently traded up my AKG Q701s for a pair of HD650s and I am blown away. I love these cans! I liked the sound of my 701s before, but I found them fatiguing to listen to, and I was missing the bass. I love the bass impact when watching a movie like Jurassic Park on my computer and the 701s wasn't cutting it. The 650s are blowing me away and absolutely love the sound signature. So now to the point, I want to have that same sound signature everywhere I go. I have a pair of klipsch X10s and I am happy with them, but I'm thinking of switching them up for ie8s. My question to you Head-Fiers is, does the ie8 have a similar sound signature to the HD650s? Would you suggest I upgrade, or is it not worth while since I have X10s? I listen to all types of music, although I would choose a headphone more for classical music, jazz, and electronic music. Thanks for your help!
