Received my replacements from Nuforce a couple of days ago to replace a defective unit.
This one seems fine but, one thing I notice is that if I have the left earphone in and try pushing it in more or wiggling it around, it produces a crackling sound.
Listening to music sounds fine, but the crackling sound appears only when I try pushing the left earpiece in more. The right side doesn't exhibit this problem.
Is this normal or in need of another replacement?
