Also, the product may not operate correctly if you are wearing gloves or if your fingertips are too dry. The product may not operate correctly if the touch sensor is dirty from sweat. Remove the dirt before operating the product. 6 About the active noise-cancelling function The product is designed to use its built-in microphone to pick up noise from the surrounding environment (noise from vehicles, noise from air conditioners, etc.) and to cancel out that noise by producing sounds in negative phase. This results in a reduction in the sounds in your environment. The product's noise-cancelling function is mainly effective against noises in the lower frequency range, but not all noises are cancelled. Depending on the type of noise (or in quiet locations), you may not notice the noise-cancelling effect. A slight humming sound may be heard when using the noise-cancelling function. This is a sound generated by the noise-cancelling function; it is not a malfunction. The noise-cancelling effect may vary or a bleep (howling) may occur depending on how you wear the product. In these cases, take off the product and put the product in your ears again correctly. To maximize the noise-cancelling effect, select the eartips that offer the best sound insulation for each side to block surrounding sound, and insert the headphones into the ears correctly. When you use the product in a train or a vehicle such as bus or truck, noise may be heard depending on rail/street conditions. 7 About water-resistant (drip-proof) performance The water-resistant (drip-proof) specification of this product applies only to the headphones, not the charging case. Although the headphones have water-resistant (drip-proof) capabilities equivalent to IPX4, the part where the sound comes from is not water-resistant (drip-proof). The water-resistant (drip-proof) performance is designed to protect the headphones if they get wet from rain, etc. (equivalent to IPX4). JIS/IEC protection grade IPX4 means that the product is protected against exposure to flying water from all directions. The headphones cannot be used underwater. The headphones cannot be used in hot and humid places, such as bathrooms. The headphones are not waterproof. Submerging them in water may cause damage. The headphones may not function properly if they become 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. 8 For a more comfortable Bluetooth communication experience The effective communication range of this product varies depending on obstructions and radio wave conditions.

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 or may not turn on if they 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, etc. 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 openings such as the sound reproduction part, microphone, or vent (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 USB 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. 1 2 3 4 3 1 Eartip attachment part 2 Sound reproduction part 3 Microphone 4 Vent 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. 34 Eartips Selecting eartips To provide better fit, two types of eartips are included with this product. Use the type that fits you best. Eartips are provided in four sizes (XS, S, M, and L). This applies both to the soft eartips (ER-TW32), which reduce strain on the ears even when used for long periods of time, and the firmer normal eartips (ER-TW1), which are designed to provide better fit and stability. At the time of purchase, the M-size soft eartips (ER-TW32) are attached to the product. ER-TW32 ER-TW1 Eartip size The product includes two types of silicone eartips in four sizes (XS, S, M, and L). At the time of purchase, the M-size soft eartips (ER-TW32) 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. 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. 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. 35 Forced pairing mode / reset If the product does not connect to a device (forced pairing mode) If pairing cannot be cancelled or is not successful, you can use forced pairing mode to perform pairing again. 1 After both headphones (L (left) and R (right) sides) are placed in the charging case (with battery remaining) and the headphone indicator lamps turn on, touch and hold (about 4 seconds) the touch sensors of both headphones. 2 When the indicator lamps on both headphones light in orange, release your fingers and remove the headphones from the charging case.
