What would be involved in making this happen?  I have an amp that has 220V input, but since I don't live in europe it's somewhat annoying.   I'm not asking for step by step obviously since I don't have any specifics on the output of the power supply or anything, just a general would would...

I have a pair of PX 200's that my dog ate.  They are fine other than torn up pads, and I had to cut out chewed up arts of the cable leaving me with delicate soldered connections.   I wondering if there is anything fun I can do with the drivers though, other than buying new parts and fixing...

So I finally decided to open up my cans to see if there was any hairs on the driver causing rattle.  I've had these sitting aside for well over a year now because I was afraid to crack them open all the way.   When I got them open, I actually did find many hairs clinging to the sticky driver...

I'm not sure how old they are, maybe 3 years, but I've noticed that the right side now makes a crackle sound. I actually haven't used them in months because its so annoying. I'm no tech or anything, but I opened them up, and to me I see no issues. No tears or anything. What can I do about...

Anyone know how to get these open? My dog chewed on the cable and bit it off right at where it exits the headphone. Cushions are messed up, found those online though. If anyone has any insight on how the black part pulls away from the white part (I have the white ones) I'd appreciate it...

I'm looking to get a pair of headphones for a girl as a Christmas present. She is just using the normal ipod ones that don't fit in her ears. I want to get her something along the lines of a px-100 in function... but not price or sound quality. I found a pair of JVCs that are somewhat similar...

I recently purchased a HP laptop, and I'm looking into getting a usb DAC for my headphones and to hook up to an amplifier. the laptop is a dv5t and the headphones I have are Beyerdynamic 770 pros of the 8ohm variety. the amp I'm looking into is this Amazon.com: AudioSource AMP-100...

I have a pair of Beyerdynamic 770 pros with red leather pads on them. The leather is starting to look pretty nasty where I grab them all the time with my hands. Any methods of cleaning then without removing the color?

Does anyone know of a good, cheap and easy kit to build to power speakers? I'm looking for something in the rage of $50 and maybe about 20W or so.

I build a CMoy pretty much to the exact specs on How to Build the CMoy Pocket Amplifier. While it does amplify the signal, by mean of making it louder, I don't notice any difference at all in the sound quality. I was hoping of getting a little more bass, but that is not the case. I have...

could someone with px100's or px200's post a picture of the drivers? doesn't have to be too extreme, just remove the pads and snap a picture.

I bought some Sennheisers off ebay and I think they have been tampered with. How do I go about opening them up to check? I have a cheap pair of koss headphones and the quality of them seems to be better. Nevermind... they seem legit, I was just overwhelmed about how much more bass the Koss...
