In 2018, KBEAR founders team with the help of a Japanese Designer developed high-end HIFI headset products to meet the needs of the global music market with an immersive music experience. Thus, TRI was founded! The flagship product I3 of the "TRI" brand was launched in 2019 - A Breakthrough. This product puts a 10mm flat diaphragm unit, a composite 8mm dynamic driver, and an advanced balanced armature into the earphone cavity. TRI I3 can be regarded as a sound unit in the HIFI headset manufacturing process. It allows the listener to experience the atmosphere, giving the sound a color and shape. TRI is coming up with more of such products in the next segment!
