Except that when if clicks on playback, the click goes through the headphone, quite loudly.

HI everyone, just got my hands on one of the new Xduoo X20 (from an ebay seller) and I'm getting a clicking noise whenever I insert/remove my iems as well as on the first playback after inserting my headphones.. What is this and how do i fix it? Here's some i caught after removing my IEMs...

Hi, I'm Dreadslacks, or slacks for short. I'm barely (xD) a new entrant to the Audiophile world, currently rocking 2 iems (ATH-LS70is, TFZ Series 2) and one headset for gaming (Sennheiser GAME ONE) One day I'll own a set of headphones I don't need to upgrade.... one day.
