This is a fair-to-good ask at US$50. The HS02 launched at US$99, and current listings still cluster around roughly US$99 to US$109, so US$50 lands well under typical new pricing and looks attractive for a used unit if it’s complete and working properly.
It’s a solid buy if you need USB galvanic isolation to cut noise and break ground loops in a desktop system, especially with a revealing DAC/transport chain. The upside here is that it’s a relatively recent, simple box with a clear job, so a clean used sample can be good value; I’d just confirm it includes the needed cables/adapters and that the inputs/outputs are all stable, since the value is mainly in hassle-free functionality rather than a lot of cosmetic collecting appeal.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
