final A4000 Single High Precision Dynamic Driver IEM Earphones With Detachable Cable.

final A4000 started by establishing a new development and production base in order to achieve a level of sound quality that cannot be achieved at this price. final have newly designed a 6mm dynamic driver with sound quality based on the original evaluation method established at the time of development of the flagship earphone A8000. A wide range of music has realized the impression of transparent sound, which is a sound that can be heard clearly even if it is localized at a distance. The development of the A series began with the establishment of a new evaluation method by analysing the relationship between sound quality and physical characteristics; the result was the A8000. The A4000 has further evolved that evaluation method. As a result of a new research targeting an evaluation method that matches the actual music listening situation, final were able to produce a product that can be said to be the definitive edition in this price range.
