No bass from the right speaker
The stock headphones of my iPod nano (2nd generation) play no bass from the right side (and the right speaker sounds less loud). There are no broken/pulled out wires, and other headphones work fine with the iPod.
I am comfortable with splicing/soldering headphones, but I can't identify where the problem is. Is this a contact/connection problem or is the speaker (woofer) faulty?
