I've tested with multiple sources and with different headphones. Both tests lead me to believe that it's a problem with the T5p themselves.
The problem is the left channel will completely cut out or have a lot of static which is probably due to a connection problem. I tried fiddling around with the jack while it was plugged in but this had no effect. Then I tried moving the cable connecting to the cup/driver around and it would cut out depending on the angle it was at.
After thinking about how this would have happened as I take very good care of my headphones, I realize that the design of the carrying case crushes the portions of cable connecting into the cups which seems like a huge design flaw to me.
Anyway, I have no experience at all with opening headphones or soldering so I'm wondering what I should do?
The problem seems to be getting worse and it's very noticeable now.
I'm not totally deficient with using tools and can learn very quickly. Should I do it myself or sed them in as a defective pair? I currently don't have a secondary pair of headphones to use for the time being and I'm going on a trip this weekend.
So basically is it difficult to fix? If not, how would I go about doing this?
