Victor Company of Japan, Ltd., showcased its latest replacement ear-tip under its JVC branding at the Tokyo Headphone Festival 2019 Spring. The new Spiral Dot ++ is the company’s third generation replacement ear-tip under the Spiral Dot series after Spiral Dot and Spiral Dot +, the latter is not available for retail sales and is packaged with the company’s Flagship offering such as the Victor HA-FW10000 which I tested with the Spiral Dot + and the Spiral Dot ++ at the Tokyo Headphone Festival 2019 Spring.
Being the company’s latest offering in the Spiral Dot series, the Spiral Dot ++ continues to employ the company’s unique “spiral dot”, in which dots are arranged in a spiral on the inner wall of the ear tip. By diffusing the reflected sound in the ear tip and optimising the balance with the direct sound while suppressing the noise and realises a clear sound.
The company also adopted the “SMP iFit” material from SMP Technologies previously used on Spiral Dot +. SMP iFit has Dynamic tan δ (vibration absorbing property) similar to that of the human skin; when used in a part that touches the human skin, it can realise natural comfort. Among the variations of SMP iFit, the company selected a grade with a smooth touch and finished it with a hybrid structure combining high-quality silicon to reduce shift and dropout due to the characteristics of the material. Moreover, in order to fuse different materials while taking advantage of the two material properties, the joint has a unique wave shape.
Available in 5 sizes, S / MS / M / ML / L, each package of Spiral Dot ++ contains 4 (2 pairs) replacement ear tips. The ear tips are made in Japan with its recommended retail price at JPY 2,500 excluding taxes. When speaking to representatives of the company at the Tokyo Headphone Festival 2019 Spring, I was told that the first shipment of the Spiral Dot ++ was sold out in Japan with the next shipment scheduled to be in July 2019.
