Description

The TRI i3 MK3 is the third generation of the Planar+BA+DD hybrid flagship IEM, designed to deliver a delightful timbre similar to electrostatic drivers. The CNC-AL body with purple anodized processing ensures durability and maintains a refreshed appearance. The 10MM flagship planar driver is dedicated to treble, providing an exceptional high-frequency experience.

The SONION 2356 BA driver is selected for balanced and natural mids, maintaining the smooth vocals and cohesive instruments from the i3 Pro. The redesigned 10MM beryllium diaphragm DD recreates an expansive soundstage with quick response and better resolution. Independent acoustic chambers and Knowles acoustic dampers ensure a cohesive and balanced sound, filtering out roughness and sibilance.

The TRI i3 MK3 retains the expansive soundstage and high resolution of the i3, along with the captivating bass and smooth mids of the i3 Pro. The planar driver delivers wonderful treble with a sense like electrostatic drivers. The overall sound is balanced with a pop feeling, providing enough bass and details for various tracks, especially when paired with a powerful player.
