【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】

■ Voltage Compatibility This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).

Many regions use 120V or 220–240V. Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.

■ Plug Type This product uses a Japanese plug (Type A or B). A plug adapter may be required depending on your region.

■ Transformer Requirement (Very Important) A transformer is required for safe use.

A plug adapter only changes the plug shape and DOES NOT convert voltage. Using this product without a transformer may cause serious and irreversible damage.

■ Buyer Responsibility As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.

■ No Return / No Refund Policy We do NOT accept returns or refunds for: ・Voltage mismatch (including 120V and 220–240V environments) ・Use without a transformer ・Plug incompatibility ・Damage caused by improper setup or usage

■ Liability We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.

■ Final Notice Please ensure full understanding of the above before purchasing. Use only under the correct voltage environment. [Easy to connect and enjoy] A conversion cable that converts to an earphone jack. If you are using a smartphone, amplifier, audio player, or other device that does not have the desired earphone jack, simply plug it in and it will convert instantly. [Bass Adjustment Function on Cable] The cable features adjustable bass for both left and right channels, allowing for precise sound quality adjustments to suit your preferred music. By adjusting the impedance, you can eliminate low-frequency noise and audio dropouts, enhance the bass, and reduce the treble. [Adjustable Bass] By turning the included screwdriver, the resistance value changes, allowing you to control the bass of the left and right channels. There are 11 settings, and each adjustment is possible within a 50Ω range. [Achieving Clear Sound Quality] By using 18 strands of high-purity oxygen-free copper (OFC) per core, resistance in the transmission of audio signals is eliminated, resulting in clear sound quality. In addition, the 8-core configuration not only increases the strength of the cable but also maintains a wide frequency range, improving spatial expression while maintaining a natural sound. 【Excellent Durability】The outer covering is made of PVC, which is highly flexible and durable, making it easy to handle and less prone to touch noise.
