Hi everyone,   I broke a stereo plug into my audio jack a few months ago, so I ended up buying an external USB sound card recently (Behringer UCA202). I'm having an issue where, when I am playing sounds or music, I get occasional crackling and popping noises. This never happened before. I...

Hi everyone,   I'm having some serious issues re-terminating my Yuin PK1's. There is a coating on the cables (once the shielding is removed) its blue in color and meant to be the insulation between the signal cable and the shielding and it inhibits soldering and is impossible to remove.  ...

Hi everyone, I'm looking for new full size headphones. Currently, I have Sennheiser 212Pro's, and I enjoy the amount of bass they have as they are DJ headphones, but they are badly lacking in highs. The highs are somewhat drowned out. I also own Yuin PK1s, and I really enjoy their top knotch...

Hi, I have a CMoy amp (see sig). It doesn't seem to do much for my Yuin PK1s...the only function I have noticed is it being able to increase the volume which isn't useful for the PK1s with neither my computer nor my iPod. They already get plenty loud. What exactly is the amp supposed to...

Hi everyone, I'm starting to notice that the plug on my Yuin PK1s is going bad. When the wire into the plug moves a bit, the left ear sound range gets messed up (I lose some of the highs and lows but not mids). What kind of price range should I be expecting to pay for a fix for something...

Hi everyone, I'm planning on building my first headphone amp soon (CMoy) and I'm looking to buy a few different Op Amps to play around with. I'm having trouble finding a place that carries a all of the stuff I'm looking for as I don't want to buy from separate places and get slammed with...

Hi everyone, As you can tell, I'm new to everything about headphones, amps, and personal sound systems like this. I was reading through Tangents "Notes on Op Amps" and he was using terms like "laid back" and "aggressive" to describe the sounds of systems or op amps. What do these terms mean...

I'm thinking about building my first amp, I'm still learning about everything. Would a CMoy amp benefit my Senn 212Pros? Would they benefit if they were plugged into my computer...would the benefit if they were into my MP3 player? I'm just wondering how much of a difference I should...

Hi everyone, I'm getting a new MP3 player soon, and I need new cords for my Sennheiser HD212Pro's that aren't 10ft, because it's just way too long and lanky. Where can I find replacement cords that are much shorter? And no, I do not want to modify my current cords because I need them. I'm...
