Hello everyone on the forum. A few years ago, I bought the Fiio Fh5 headphones, and they've been working great until now. The left earpiece suddenly lost sound, and I initially thought it might be the cable. Without further testing, I bought a new cable, but the left earpiece still didn't work, producing very faint sound when turned up to the maximum volume. Then, I switched their positions on the old cable and confirmed that the issue isn't with the cable but with the left earpiece. I was using an LG V60 as the source. I also tried them with a Dragonfly Black DAC, but the left earpiece still didn't work. Is there any possibility of fixing, or should I consider throwing them away and moving on?
