On June 16, 2022, #FiiO 2022 Summer Launch Event II# will get to us. Let's stay tuned for it!
Inspired by the traditional Chinese musical instrument, "waist drum", FiiO's design team created a "drum" type bass cavity for the flat-head earbuds FF3. This cavity was specially designed to fully harness and utilize resonances to more effectively bring out the texture of bass notes. Meanwhile, the team made full use of the internal space of the FF3's housing to fit a bass-enhancing acoustic tube within. Therefore, the FF3 has an effective frequency range down to 42.5Hz for truly deep earbud bass under normal open wearing.
