To create the best and the most natural sound qualities, Final Audio has developed and whole new dynamic drivers called 'f-Core DU'. Every detail and part has been developed and designed by the tuning engineers from Final Audio to achieve the best sound performance. 'f-Core DU' has used brass in manufacturing the housing of the drivers, which can significantly minimize the effect of magnetic force on the driver in use. To avoid inconsistency in the production of drivers, Final Audio has adapted a finer manufacturing method with the amount of only one-third of normal production. Such differences have successfully created the natural sound with high authenticity and quality.

Final Audio has developed and scientific and objective tuning methodology to achieve best performance. Such methodology has been applied on the previous flagship model A8000 with great success, where it is believed PTM could bring decisive effect to the sound quality of IEMs.

A3000 comes with a handful of accessories that match the needs of all users, including Final's well known Type E Earpiece in different sizes and the new Type B Ear Hook. Type B Ear Hook is made of soft and durable silicon, providing comfortable experience to users and minimizing noise created under the Stethoscope Effect.
