【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.

[Results of joint research with Kyushu University] Through joint research with Dr. Kazuhiko Kawahara of the Kyushu University Graduate School of Design, we have discovered a physical property that makes speech easier to hear. The result of this research is STUDY 1, earphones designed specifically for learning that improve your ability to concentrate on your voice. As a result of a subjective evaluation experiment, a statistical hypothesis test confirmed that "STUDY 1" has a significantly higher "correct answer rate for how well you can hear conversations" than other music earphones.
[Adopts soft type earpieces] Final's ``TYPE E'' earpieces, which have a reputation for their excellent fit and sound insulation, are included in the package in 5 sizes: SS/S/M/L/LL, which are less tiring even when used for long periods of time. In addition, the right side is white and the left side is clear color, making it easier to distinguish between the left and right.
[Unique Swing Fit Mechanism] The swing fit mechanism allows you to swing the earpiece from side to side to perfectly fit the inclination of your ear canal. Prevents deformation caused by the opening of the earpiece hitting the auditory canal. Sound is transmitted directly to the eardrum, achieving clear sound.
[Equipped with a hands-free microphone] Equipped with a hands-free microphone, it can be used for a wide range of purposes such as online classes, English conversation training, and web conferences. In addition, it is equipped with a one-button remote control that allows you to play, pause, rewind, and fast-forward content, as well as answer incoming calls.
