Thank you for the reply. I thought it was some auto shutoff circuit. I'm using HD 650 headphones. I also hear a very loud pop in the headphone if I pull them from the jack.

Got my new Valhalla 2 last week and noticed something strange. Wondering if anyone else has had this problem. I unplugged my headphones to plug in elsewhere without powering the amp off and the amp shut itself off. I had to power the amp off and power it back on to get it to come on again. Tried...

Thanks for the help. Some really smart people on Head-Fi!

Hi all,   I use a NAD CD player as my source most of the time. I would like to be able to switch from my headphone amp to my integrated amp (when listening to speakers) without swapping cables. Anybody have a suggestion?

What are you using as a source? I was going to hook up the Valhalla to my cd player.

Also take a listen to Macy Gray's new album Stripped. As good as it was through speakers, it was even better with the HD650's.

My amp does not have the -20db button. I just wondered why the HD650's seem easier to drive on my amp than other headphones.

Hello everyone,   I usually play my music through an early 90's luxman amp. With my Sony MDRV6 and my Grado SR80 headphones, I usually have the volume 1/4 the way up to listen comfortably. However, with my recently acquired HD650's, I have to lower the volume down to about 1/8 to listen...

I listened first on a Yamaha desktop radio (with speakers) and thought yeah, this is pretty good. Finally listened to with my headphones after a trip this week and wow! Amazing sound. Thank you Dr. Chesky; hope you keep recording music this great.

I just picked up some HD 650's too, and to my surprise I have to crank up my fiio x5 way way up to just hear the sound. I don't have that problem with my momentums.  I didn't try with my phone yet but I am expecting similar results. But running the 650's off of my luxman integrated amp, I have...

Also check out Alexis Cole's release from Chesky. Heard it at the New York Audio show this weekend, demo'd on a pair of Stax headphones and bought a copy right at the show.

Good news,   Comply has a solution for us. Just got this email today, and they remembered....what a company:   Hope you’re doing well! I wanted to let you know that our engineers have tested the Sennheiser Momentum earphones and they have found compatibility with our T-150 Comply Foam tips...

I have the same problem, mediums are too small, large are too large. Let me know if you find a fix. I have read many similar complaints.

I saw these in Sears and was struck by how similar they look to the momentums. So cheap I almost bought them just to give them a try. Nakamichi was once a very will respected brand. Any one heard these?  ...

Reading your post, I was surprised that you like the font size. I read several complaints about this somewhere else. Did the font size change with the new firmware? Is it possible to do that?

Thank you. Enjoying some music now. Downloading music was simple too. The font on the X5 is really small.

Can someone tell me how I go about updating the firmware on my x5 to 2.0? Do you just download the software to the sd card off the card reader, or do you need to download the firmware to your computer and then move to the card? Very new to this stuff so I would appreciate some detailed...
