Hi everyone, my Sennheiser HD 205 recently started making strange distant sounds out of both sides. The sounds are hard to describe but what I know for a fact is that they are not random. The high pitched blurry sounds are always in rhythm with the song. Like if for example the bass drum is transformed in this sound so every time you would normally hear the bass drum beat, you now hear this strange high pitched and distant sound instead of the bass drum. I already tried using my headphone on different sources but the problem persists. I also tried other headphones on these sources and got perfect sound so the problem is with my Sennheiser HD 205. Also I said 'distant' because the music sound very far away when using the Sennheiser. I tried turning up the volume to Max. but the sound couldn't get above a certain decibel level and kept sounding far away. Experts and genies help me out please!

the problem is the cable from one driver to the other suffers from fatigue due to the bending of the plastic frame as the headphone fits to your head, causing copper cables to disintegrate.
the solution is to take apart the headphones (mini and regular Phillips screwdriver ONLY required) and solder a new cable in. in my case i used a standard coaxial cable for replacement.
once you have split the end of the senheiser cable output from cup 1 into its two parts you need to attach it to the equivalent connections on cup 2 (which u also need to split, i suggest using a modeling knife)
the red wire is insulated with ceramic coating much the same way as an electromagnet winding, the other is standard copper. you must attach copper to copper red to red with YOUR OWN cable.
the most difficult part is removing the ceramic insulation coating on the red wire, which i removed with a blast from a cigarette lighter. simple.
problem is your cable probably will not fit in the slot designed for the previous cable so i drilled a small hole in the BACK of the cup (silver colored horse shoe shape) and ran the cable outside the plastic case. not pretty but it saved me £40 for 2 hours work, which is not bad.
i am a trained mechanical and electrical engineer so u can trust.

Although I'm not an expert I'm not quite sure if armadillopic is right. I had the exact same problem and managed to overcome it by replacing the cable from the headphone to the mini-jack plug. I actually only had to renew the last bit of the cable but chose to replace the entire cable. I found out that when I bend the last part of the cable in the exact right position the strange high pitched sound that was going over the vocals went away and the vocals became much louder and clearer like they normally did. Perhaps you can try if this works for you as well? Just bend the last end of the cable in various kinds of positions (NOT TO EXTREME OR YOU WILL ONLY DAMAGE THE CABLE MORE!). Hope you are able to narrow down the problem to just the cable. Greetings!

Thanks for the reply armadillopic, I saw you post this solution on a previous topic also about sound problems with the HD 205. Although your suggested Solution makes sense, I don't think your right. A couple of days ago I tried the HD 205 again and found out that when i bend the end of the cable where the 3.5mm mini-jack is fitted on, the sounds becomes perfectly clear as long as I bend it in exactly the right position. You think it's just a broken cable problem? Or might it still be also a problem with the cable from one driver to the other? I'm not an expert so I'd like to hear your thoughts about this. Thanks
