Final Audio A4000 Sound Isolating In-Ear Headphones
Description
Final A4000
Earphones with Detachable Oxygen-Free Copper Cable
A4000 delivers an impressively wide soundstage and surprising audio detail for its price point, with a comfortable lightweight build that features replaceable cables. Achieving this required the development of a new f-Core DU dynamic driver that can recreate an impressive spatial sound, with a strong sense of direction and spacious staging.
6mm f-Core DU Dynamic Driver
A4000 delivers bright detail reproduction with a wide soundstage. In order to achieve sound quality rarely found at this price range, Final developed the 6mmφ f-Core DU dynamic driver unit from scratch with the latest psychoacoustic research in mind. They designed not only parts for the driver unit — the diaphragm, voice coil, magnet, magnetic circuits, adhesives — but also the production machinery used in the manufacturing process. For the driver front housing, instead of the typical aluminum, they used brass, a material that is both highly resistant to the effects of magnetism and also boasts a high specific gravity. In order to increase the time response characteristic of the diaphragm, the voice coil employs a 30μ ultrathin CCAW, and minimal adhesive is used for assembly to thoroughly lighten the moving parts, improving listening comfort and reducing distortion.
Ergonomic fit
Final A4000 is a lightweight earphone, carefully sculpted to fit many ears. Like a professional custom in-ear monitor used by musicians on stage, it is designed to be worn with the cable hung over the ear, minimizing cable noise and allowing a more secure insertion. By limiting the area that comes in contact with the ear, this product aims to limit discomfort over time by minimizing points of contact.



A4000 comes bundled with premium quality ear hooks. Use these optional silicone hooks — then thread the cable up and over your ear — for an even more secure fit and reduced cable noise.
