DEMO UNIT

A Piece of Art
The piece is made of 6063 aviation aluminium alloy which is well-carved and formed. Three little squares integrated as a whole without any splicing. The seemingly irregular shape is in fact very symmetrical, holding it in the hand feels like playing a pressure-relief toy.

A Choice to Make
The L-shape is the first choice, and it can also be other shapes, such as long strip, square, etc. The L-shaped design enables you to experience various using environments to use with your L-shaped earphones to connect to your laptop, or bend it to the back of your phone, etc.

All-New Powerfull Decoding chip
It adopts the ES9281AC PRO from ESS company as the decoding chip.

RGB Indicator Light
In addition to indicating the On and Off status*, it can also identify different sampling rates of files with different colours, including red, blue, green, yellow, white, and magenta. *The indicator light will flash blue, green and red alternatively after being inserted to the phone, but it only works when the earphone is plugged in. The indicator light will be on steady when playing music.

MQA
MQA official certification. MQA enabled renderer that will complete the final unfold of an MQA file. The LED glows magenta to indicate that the unit is rendering an MQA stream or file. This delivers the final unfold of the MQA file.

Auto Detect Headphone Impedance
Before use, please insert the earphone to the TC35 Pro first and then connect it to your phone. In this way, the device will automatically detect the headphone's impedance and switch between low Gain and High Gain modes. For instance, when high impedance is detected, it will then switch to High Gain mode to output.

A Time of Exploration - Why is it called 'Tetris'?
Tetris is a game that almost everyone recognises and has played. The geometry of the squares, and the combination of quantity and direction, exist not only in the game, but also in our lives. During an exploration, we focused on these small squares and used such shapes to make products that are convenient for us to use. Note, 'Tetris' here is just an image metaphor, not the name of the product.
