Response to Cable Concerns for HiBy Digital Xeno

Thank you for your interest in HiBy Digital Xeno. We have received some questions about the cable selection from reviewers in our advanced testing.

HiBy Digital Xeno adopts heterogeneous DAC and active crossover design to drive xMEMS Cowell and graphene DD, therefore, its control chip and circuit design is quite complex, which is comparable to high-end Dongle DACs.

To improve the convenience of operation and to reduce the burden of connecting the TYPE-C plug to the socket (this is the same as the HiBy Digital Xoe, also digital earphones, which also have a built-in independent DAC), we integrated the digital processing part, in the center control, instead of leaving it at the TYPE-C end. Thus, the Xeno's mains cable needs to carry the HD digital signal and transfer the full HD music file to the master chip in the center control for processing with virtually no latency. Therefore, the main cables of Xeno and Xoe need to be made according to the specification of HD digital cable structure, which is different from the traditional wired headphones, because the traditional wired headphones cable, only needs to transmit the analog signal after digital decoding.

However, both Xoe and Xeno are, after all, earphones for everyday use, so the cable's thickness, softness, and length all need to be adapted and adjusted according to ergonomic conditions. In order to make this digital main cable closer to the physical sensation of ordinary earphones in terms of length, diameter, and softness, we have made dozens of adjustments to the basic structure of the cable, from the material, diameter, and winding method of the transmission conductor, to the material and thickness of the core, to the structural adjustment of the ground wire, to the shielding material, shielding ratio, weaving method, and even the proportion of the shielding mesh wrapping. Each place has been adjusted and tested. A slightly longer or shorter overall length of 1cm may result in different percentages of packet loss for digital signals at different frequencies; the higher the proportion of the shielding mesh, the better the shielding effect, but the harder it is to use, however, if we reduce the proportion of shielding, it will also increase the instability of the signal transmission. For each of these adjustments, we needed to conduct a complete hardware and software match test. Despite the previous experience of Xoe's R&D, the process of adapting the digital mains cable for Xeno still took more than half a year of repeated debugging and verification. So far, the Xeno's digital cable, due to the customized shielding layer, is not as thin and soft as traditional wired earphone cables, but in the process of unfolding, it is very close to the weight and softness of wired earphone cables.

In addition, for the around-ear-wearing part, the left and right channel cables are earphone cable structures for transmitting analog signals, so you can also experience the difference with the main cable. The around-ear fit reduces the audible effect of the cable rubbing against the collar, and in the official product packaging, we also include a collar clip to secure the cable to the collar, thus further reducing the wobbling of the cable.
