【Cautions for using electrical products】
When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions.
Since the plug type is Japan type(A or B type), please check the voltage and use a transformer.
Please note that a transformer is different from a conversion adapter.
We are not responsible for malfunctions caused by use without a transformer.
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[High-quality sound specifications, awarded VGP and Headphone Book] Each note is crystal clear, and the sound attack is quick, so you can hear the timing of vocals and instruments clearly and clearly. This allows you to feel the excitement of music more than ever before, and even familiar playlists will be filled with new emotions. These earphones have been awarded with the largest audio-visual award in Japan and the Headphone Book, a comprehensive guide to the latest earphones and headphones for music fans.
[A customized fit] Based on the optimal housing design for IEMs, we chose a shape that limits the contact area rather than a large, organic shape that comes into contact with the ear, in order to achieve a comfortable fit without feeling oppressive. With ergonomics in mind, we have created a design that puts no strain on the ears without relying on the resilience of silicone.
[2-Pin Connector] The 2-pin connector is a high-precision product developed in-house. It uses the φ0.78 standard, considered the most versatile. The soft, flexible coating material takes touch noise into consideration, allowing it to flex flexibly even when using ear hooks, ensuring a comfortable fit.
[In-house designed eartips with a tight seal] Two types of silicone with different hardness are used for the sound conduit and the earbud that comes into contact with the ear. The sound conduit uses harder silicone than the earbud, and by applying grooves to it, it combines strength and flexibility. The earbud that comes into contact with the ear uses softer silicone, achieving a comfortable fit and high level of sound insulation.
[Included items & notes] final A4000 earphones, 2-pin OFC 3.5mm cable, ear tips (TYPE E 5 sizes), instruction manual, 24-month warranty, customer support *1 This product does not have a microphone function.
To achieve high sound quality, the A4000 began with the establishment of a new development and production base. The 6mm diameter dynamic driver was entirely redesigned, including not only the components but also the production equipment. The sound quality was designed based on final's unique evaluation method established during the development of the flagship earphone, the A8000. The A4000 features an overwhelmingly natural sound, with each sound clearly defined and positioned to emerge from the spacious, wide bass range.
