The stock cables came loose so I added some silver plated copper wire. These were easier to re-solder than most IEMs I have tried.
You need to be very careful with IEMs it's very easy to destroy them while soldering. The Copper's were fairly easy to work with though they don't have the standard design of other IEM's I have worked with. The solder points are actually a layer away from the inner workings of the driver not right on the back of it.
hey danthrax, this is honestly my first post, aha just joined to ask you for some advice on rewiring my copper turbines (no inline control, same as yours), so please let me know how you did it successfully, because i ruined my brother's last pair of turbines while trying to rewire them, his turbine lost sound in the left speaker as did mine last week, not completely but enough to ruin the music. also i think i'll use an apple headphone wire (standard, no mic) to rewire them. so please let me know anything you think would help me do it right this time!
These are honestly garbage headphones, the Klipsh x10 are 1000x better and are like $130-140 on Amazon regularly, and drop down to $80-100 around the holidays. Plus they don't break after a month or so.
