The body of the model is made of aluminum and partially covered with leatherette. The player has a compact size of 109.7 x 60 x 18 mm and weighs 125 grams. The controls are made in the form of physical keys and a multi-functional wheel, and to prevent accidental clicks, the buttons are locked.

3.5 and 4.4 mm jacks are provided for connecting headphones, there is a separate line-out on the 3.5 mm jack, and the USB-C port is designed for both charging and digital signal transmission when using the device as an external DAC. There is also a Bluetooth module on board with support for SBC, AAC, AptX HD, LDAC codecs.
The DAC chip is called Hymalaya, it is manufactured by the company Hifiman on the basis of FPGA and, according to the company, has a lower power consumption compared to traditional chips from Burr-Brown, AKM and ESS. True, the player itself lasts only 9 hours on a single charge, which is quite a bit.

The amplification part of the player is modular, and the customer can choose between normal and balanced amplification. Replacing cards is done by removing the back cover of the device
