New Drivers for Enhanced Clarity & Soundstage

Over the past few years, TFZ has become one of the Massdrop community’s favorite manufacturers of value IEMs. With the King Pro, the company brings that value to a higher-tier IEM. It features the latest acoustic and material technology, including a new generation of 12-millimeter dual magnetic self-frequency graphene drivers and a 5N oxygen-free-copper wire. These make for a high-resolution experience with enhanced clarity and soundstage from the original King model. The King Pro has a two-pin connection should you ever want to swap in different removable cables, and comes with seven pairs of ear tips to help you find the perfect fit.

Note: At checkout, you’ll have your choice of color: blue, green, red, or red and blue.
