Plug-in headphones are no longer just a matter of walkmen and bundled rebrands for phones. FiiO engineers were well aware of this when designing the new FH7 flagship. These are hybrid closed headphones with beryllium dynamic converters with a diameter of 13.6 mm. Four BA inverters help in each handset. The cable has a silver-plated connector, a braided OCC cable with eight separate fibers and MMCX connectors for the inverters themselves. Special sound chambers with the patented TURBO system for boosting the bass band. In the package you will find not only 2 portable cases, but also 15 types of plugs, a magnetic cable organizer and a cleaning brush.
