Yuin OK1 Review | The Headphone List

If I were evaluating the Yuin OK1 on sound alone, the $230 price tag would not be difficult to justify – the incredibly airy and delicate sound of the Yuins is sure to find many fans among those who prefer a more realistic listening experience. As a total package, however, the OK1 lacks the advantages so many higher-end IEMs provide.
