Trying to sell but struggling to find a buyer from Europe. It's not the tangling, it's the J-cord. I much prefer Y-cords because the J-cord (Or U-cord as the AT Japanese site refers to them as) practically pulls the left side earphone out of my ear when I'm walking due to it being shorter. The included clip didn't seem to help either. The sound is sooo good to my ears though after being used to my FX101s.
Are you are wearing it correctly, right side cable draped behind your neck? That shouldn't happen unless the whole cable is too short for you, which is highly unlikely (unless you're a 7 foot giant ).
