Hey guys,

Recently got a pair of 555's. Plugged them into my home theater receiver to watch a movie. At not-very-high volume levels, there was a pretty loud static. Can't hear it unless the scene itself is quiet but it's definitely there.

Any ideas?

it's more of a source, impedance mismatch, amplifier problem. You can test your phone on something else (e.g. PCDP, DAP, and etc) to check if the same static sound exist.

I heard a ton of static when plugging my HD555 into a crappy aiwa all-in-one stereo system, and some static also when plugging it into some Kenwood receiver. I do not hear static with the HD555 plugged into any reasonable source/amp. It is probably your receiver.

I have a similar problem. I bought HD555's less than a month ago and I can hear static while listening to music. They're connected to my sound card(Audigy 4) because I listen to music on my PC. The static is not loud and only occurs in some slow songs that are not too loud but have some loud parts, ie Queen's Bohemian Rhapsody. I don't know what could be the problem, I listen to high quality FLACs encoded directly from original CD's.

Is there anyway I can test my headphones?

Try shielding the soundcard, checkout the "X-fi hotrodding" thread for more info, I think its on the computer-as-source forum here. I got quite a bit of noise out of my Audigy 2 with my 555's until I got rid of it. My external usb dac + amp has no audible noise except with very sensitive IEMs.

Don't try any of the soldering mods unless you're confident and have a fair bit of experience and good tools. Its not that hard of a mod but it IS easy to strip the contacts and kill your card, which has happened to a few people.

I got hiss from the 2 onboard sound cards I tried with the 555. I heard it was probably a problem with the source, so I went out and bought a m-audio audiophile USB and haven't had issues since.

Hmm..that's like extra 250$. When I bought these headphones I thought I was set for listening music on my PC, that's a sum of money I'm unwilling to spend ATM. Is there a cheaper solution?

Toby, I'll check out "X-fi hotrodding" thread, maybe that helps.

Thanks guys.

I got mine for $130USD at Sam Ash. The point wasn't to sell that particular device, but to reinforce that the source is probably what is causing the problem.
