ddHiFi Janus2 Review

DD HiFi Janus 2 is a completely redesigned pair compared to Janus. It only shares the same dual connector socket as the former model while the internals is entirely changed. DD HiFi has opted for a newly-developed high-speed 10mm dynamic driver unit that results in faster, energetic sound. Janus 2 has a new double-layer vibrating rear cavity for a controlled sound response. Internal wiring is customized by Effect Audio, a widely known premium cable brand. DD HiFi has launched Janus 2 in two different variants, Standard Edition and Simple Edition. The only difference between both these editions is that one includes a transparent silver-plated OFC MMCX cable while the other features a 0.78mm standard black two-pin cable. It starts at 149$ for the simple edition and 199$ for the standard edition.
