Over the summer, I was using my ck10s and all of a sudden, the left speaker sounded much quieter than the right one. I had used them for the gym until I noticed a slight crackling noise, and quickly switched to Fischer Audio Eternas because I was afraid that the ck10s would stop working. Things went smoothly until a few months later, when the above problem arose.
Now, you may be asking if I did everything to check that it wasn't just me. I will say yes. I checked to make sure it wasn't my ear by switching the earphones around. I made sure that it wasn't earwax by cleaning the silicone tip thoroughly. I also checked balance at different volumes, but the problem still persisted.
Usually, I wouldn't really mind, but the fact that these were my favorite earphones of all time for the music I listen to makes me wonder if there is anything I can do to fix them.
Also, I got these 3rd party for 200 bucks (much lower than any prices I find for potentially replacing these) and there is no warranty on them. Thanks.
