[Spatial expression of sound that spreads before your eyes where you can discover new sounds] In addition to adopting a new driver unit that specializes in delicate expression, despite the small body, we have secured ample space for acoustics on the back of the driver unit, achieving comfortable spacious bass and wide range sound. Furthermore, by applying metal plating to some of the parts that make up the chamber, we are able to reproduce a smooth, clear expression and a wide, clear sound field. [Spiral Dot Pro earpieces that improve sound quality and wearing comfort] Comes with 5 sizes of "Spiral Dot Pro earpieces" (S, MS, M, ML, L) that were first adopted in the flagship model FW1000T, allowing you to choose the size that best fits your ears. In addition to the unique sound quality improvement technology "Spiral Dots", in which dots are arranged in a spiral pattern on the inner wall of the earpiece, a convex spiral shape has been added. The reproducibility of even the most delicate sounds has been improved.

A song featuring vocals.・PROFESSIONAL 2: Tuning that improves natural spread.

[Noise canceling function that allows you to enjoy the details of the sound] The settings of the noise canceling function have been carefully selected by sound quality engineers to achieve a high level of harmony between sound quality and noise canceling effect. Even in noisy environments such as inside a vehicle, you can enjoy the details of music with natural and clear sound. "Spiral Dot Earpieces" are equipped with our proprietary sound quality improvement technology that uses dimples on the inner wall of the earpiece to suppress sound cloudiness and achieve clear sound by diffusing the reflected sound inside the earpiece that causes sound quality deterioration.
