I have both the HD555 and AD700. I have my brother the HD555 because I prefer the AD700 though because I can pick out more subtle sounds with them. They're also really comfortable. I use them with an astro mixamp though so I believe that helps a lot.

I got some on the FS forum with the HD600 grilles and HD650 cable for $175 shipped a few weeks ago. I just searched for older threads and ended up just PMing the seller and he hadn't sold it so I gave an offer and he accepted. Just gotta keep looking around.

i have one and tried it with some AD700's I had sitting around and thought they actually sounded great. next thing i knew, two hours had passed and i was still listening to music. there was a definite improvement from just plugging it into the headphone jack on my computer.

i have only one. a 30gig ipod video.

i'm glad you made this video. i got a pair of HD555 off of craigslist for $30 bucks but didn't enjoy them that much. after doing this fairly simple mod i can say i like them much better. thanks.

most people can't even tell the difference and i honestly think that most of them don't even care. on my morning commute, it seems like people listen to their ipods so that they can ignore all the weirdos on the bus and out on the street asking for money or a smoke. sound quality is the last...

Ultrasone Hfi-780. Not comfortable whatsoever.

I got mine but the sound cuts in and out. I have to wiggle the cable around until it works. anyone else have this problem?

mine should be here the 11th. got the tracking number today.

just got my shipping confirmation from logitech today. should be arriving on the 11th. also, looks like my second order was canceled.

I play a lot of MW2 on 360 and I just started using the Turtle Beach HPX through the Astro Mixamp. I was using the AD700 with the mixamp but I find that I'm using the HPXs more because of the mic and I find the bass to be a little deeper. When I don't talk though I use the AD700 because it's so...

Wow thanks for the quick response. I had no idea there were two models. He sent me pics so I'll post them when I get home. Is that a decent price for a used pair?

Hi, I'm not sure if this is the correct place for me to post this but there is a seller in my area trying to sell the HD650 for $200 and I was wondering if there was anything I needed to be sure of before buying them? Is there anything specific i need to search for that would tell me that their...

i ordered mine before work this morning around 8 am from logitech. I waited a few minutes for a confirmation email but didn't get one so i placed a second order. Turns out the first one got canceled and the second one went through. I was charged for BOTH orders though. Sorry to those who...
