Final B2 employs 1 Balanced Armature (BA) driver and adopts MMCX connectors with oxygen-free copper (OFC) cable. The cable can be replaced when damaged. A natural and velvety sound with little stress across the entire frequency range is achieved.
MIM is a process by which powdered metal is mixed with a binder to form a resin in the desired shape and applying high-temperature sintering to achieve the desired form. There is a high degree of freedom in molding the resin into the same shape as the cast, making it possible to achieve a complex internal design even with metal. In order to achieve long-Life, repairable construction, the front and rear piece of the earphone is separable. This makes B2 easy to repair for long term usage.
Superior earphone fit or not is determined by the feeling of pressure. There are products on the market with an ergonomically praised curved surface. But because the holding positions place pressure on the ear, fatigue accumulates over time. Final designed B2 to achieve fit with little pressure. Much the same as a tripod, a stable fit can be secured with 3 holding positions. This involves 2 main holding positions and 1 assisting holding position for the earphone to not slip out. In the diagram below, a total of 3 holding positions are shown. The green section is the eartip. It secures an earphone in a comfortable stress-free way. The blue section gently fits the tragus and prevent the earphone to slip. The pink section at the concha is the third supporting point. By clearly identifying the points of contact, more people’s ears can conform to a fit with no sense of pressure. The interchangeable silicone ear tips also yields a comfortable fit and a high level of sound insulation. The ear tips comes in 5 sizes – SS/S/M/L/LL. To make it easier to distinguish between the left and right earphones, one axis of the eartips is gray while the other is red. By tilting the earphones slightly and checking their color, it is easy to distinguish left from right even in a dim place.
The ear hook that Final designed has a smaller form. It does not utilize metal or resin wires and fit the ears of most people. The ear hook is slim and comfortable that you might forget you're wearing them. Cable noise – the unpleasant noise that occurs when the cable touches the user's body when they are walking – is dramatically reduced when using ear hooks. Soft, flexible coated cable material also help on this.
With this silicon carry case, the cables can be rolled up and stored easily. The earphones themselves are gently secured using thin dome-shaped silicon covers.
