sennheiser: no bass on left ear after replacing cable - HiFi Headphones Forum - online headphone & earphone community forums

spacepilot · 08-30-2011, 01:49 PM

I used a cheap iron for soldering a new cable for my in-ear-sennheisers. The iron didn't get hot on the tip but a lot too hot at it's lower side. Result: When the solder suddenly melted, the whole "plate" did move!

In a 2nd attempt I just soldered the cable again and moved the plate back (a 1mm or so). However, I now have sennheiser in-ear-headphones with chrystal-clear sound and a new cable but no bass anymore on the left ear. It's really annoying and a reason to just pay 80 bucks again buying a new pair. Before doing so I'd like to try all possibilities of fixing them. Anybody has ideas how? I don't even know how the bass get's produced inside the headphone. Should I try to lift the plate? Could wrong amount of solder cause this? I'm glad for any help.

I attached a photo showing the problem.

If you know somebody who is an electrician and has a multimeter maybe they could test the connections. You may have fused something underneath together, this sounds similar to what happens when a cable is crushed and contact is made inside the plastic coating of the cable. I'm sorry to hear about your trouble.

I went to a chinese electronics-shop and asked for help. The guy took a big magnifying glass looked at my soldering-work and stated that not all wires of the cable are actually soldered. He took a pair of tweezers, played a bit around and finally broke the cable. I asked him to solder it again looking at the professional soldering iron which was lying around, plugged in on a board behind him. He finally did it - and while fixing the cable I told him that the plate was moved in my attempt before. He said this actually can't be the problem and that it was for sure a problem with the cable. After he finished, the soldered joint looked quiete well and after checking the sound, I thankfully left the shop. My bass-problem nevertheless persists and I'm as clueless as before.
