Cleaning
Get into the habit of regularly cleaning the product to ensure that it will last for a long time. Do not use alcohol, paint thinners, or other solvents for cleaning purposes.
- Wipe any dirt off the headphones and charging case with a dry cloth. The headphones may not operate correctly if the headphones are wet. Wipe the headphones with a dry cloth, shake them multiple times to remove any excess water, and allow the headphones to dry thoroughly before use.
- Immediately wipe off sweat or any other moisture from the charging case battery jack, the headphone charging terminals, and the touch sensors. Failure to do so may result in a malfunction due to corrosion.
- Natural oils from the skin are particularly likely to build up on the eartip attachment parts (see figure). If these areas are not cleaned, the eartips can become detached. Clean them regularly. Do not touch the areas where sound is produced as they are delicate. Doing so may result in malfunction.
- If any moisture remains in the holes near the microphones (see figure), place the headphones on a dry cloth and shake several times to remove any moisture, and then allow the headphones to dry thoroughly before use.
- Wipe away any perspiration or dirt from the USB charging cable with a dry cloth immediately after use. Failure to clean the cable may cause it to deteriorate and harden over time, resulting in malfunction.
- If the USB terminal of the charging cable is dirty, wipe it off with a dry cloth.
- Clean the eartips by removing them from the headphones and manually cleaning them with a diluted mild detergent. After cleaning, dry before using again.
- ℹ️ If the product will not be used for an extended period of time, store it in a well-ventilated place free from high temperatures and humidity.
Eartips
Eartip size
The product includes silicone eartips in 4 sizes (XS, S, M, and L). At the time of purchase, the M-size silicone eartips are attached. To ensure the best sound quality, select the eartip size that is best suited for you, and adjust the eartips inside your ears for a snug fit. It may be difficult to hear bass sounds if the eartips do not fit snugly in your ears.
Replacing the eartips
Remove the old eartip and attach the new eartip by pushing it onto the headphone at an angle. Push firmly on the eartip so that the inside of the eartip expands, and push the eartip onto the post as far as it will go.
- 📖 Eartips are consumable parts that degrade through storage and use. If the eartips are loose and easily removed or if they appear to have degraded, purchase replacements.
- ℹ️ Periodically remove and clean the eartips as they become dirty easily. Using dirty eartips may cause the headphones themselves to become dirty, resulting in deteriorated sound quality.
- ℹ️ When reattaching eartips that were previously removed, be sure to check that they are securely attached. Injury or illness may occur if the eartips become detached and are left inside the ear.
Resetting
If the product operates abnormally (reset)
Reset the product if it cannot be unpaired, connected, or does not operate as expected.
1. About 5 seconds after both headphones (L (left) and R (right) sides) are placed in the charging case (with battery remaining), touch the touch sensor of both headphones twice in a row.
2. Verify that the indicator lamps on both headphones flash white, and then touch and hold (about 6 seconds) the touch sensor on both headphones while in the charging case. When the indicator lamps on both headphones light in red, reset is complete.
3. Remove the product from the list of registered devices on your Bluetooth device.
4. Remove the headphones from the charging case again and perform pairing.
