About IPX
(
IPX refers to a product's “liquid ingress protection” as cited in JIS C 0920 (the harmonized standard of IEC 60529), “Degrees of
protection provided by enclosures (IP Code)”.
(
These are provisions that guarantee the performance of a product in fresh water or tap water at room temperature. This does
not guarantee equivalent performance in warm water, seawater or the like.

Introduction > Cautions regarding product handling
Advantages of this product
This product is a set of wireless earbuds that connect to Bluetooth devices such as a portable music player or
smartphone.
High-definition playback of sound from Bluetooth devices
This product supports Qualcomm® aptX™ Adaptive as well as the SBC and AAC codecs.
Qualcomm® aptX™ Adaptive Audio is an audio codec that offers both high quality and high connectivity
performance in response to audio signal interruptions.
Supports Qualcomm TrueWireless™ Mirroring
This product features technology that lets you connect both left and right earbuds at the same time to a
smartphone, music player or other device for high-definition sound. The earbuds switch between primary
and secondary devices automatically for a stable connection.
AMBIENT SOUND
This function makes it easier to hear the sounds around you, such as announcements made on public
transportation, the sounds of passing cars and so on.
(
“Making ambient sounds easier to hear (AMBIENT SOUND)”(p.29)
LISTENING CARE
This product features LISTENING CARE, which lets you enjoy rich sound quality even at a low volume.
Focusing on the characteristics of the human ear where the low- and high-end sounds become harder to
hear at lower volumes, as well as how things sound differently in different listening environments, this
feature corrects the sound balance for the optimal sound to match the volume. By rendering a natural sound
that's easy to listen to, this feature reduces the load on your ears caused by excessive levels.
GAMING MODE
This function also makes the audio and video sound more in sync, which is useful when you are watching a
video or playing a game.
In-Ear Detection
When you remove one of the earbuds, its built-in sensor activates, pausing the playback of your audio
automatically. The audio automatically starts again when you put both earbuds back on. This is useful for
automatically operating the playback or pause controls on a Bluetooth device, such as a portable music
player or smartphone.
(
“Playing back audio on this product”(p.27)
Smartphone support
You can use this product to talk on the phone and start up the voice assistant while connected to this
product.

Introduction > Advantages of this product
Dedicated smartphone app: Headphone Control
Install the Headphone Control app on your smartphone to configure more detailed settings.
You can switch ON/OFF for AMBIENT SOUND, LISTENING CARE, GAMING MODE and so on.
NOTE
(
While the AMBIENT SOUND feature makes it easier to hear sounds around you, it does not guarantee that you will be able to hear
everything. You may be unable to hear ambient sounds if you’ve turned up the volume of the audio, or in certain situations.
(
When using GAMING MODE, the video/audio latency may change or the sound quality and connection stability may degrade,
depending on the usage environment and how you wear the product.

Wearing This Product
Putting on the earbuds
Check the markings on the L (left) and R (right) earbuds to make sure they are worn in the correct ear.
Fit the silicone fin that is attached to the earbuds into the hollow part of your ear as shown in the illustration
to keep it in place.
Move the earbuds slowly to adjust them after you put them on, so that the silicone fins fit well in the hollow
parts of your ears. Also, make sure that the earbuds are firmly seated in your ears.
CAUTION
(
Do not forcibly press on or move the earbuds once you’ve put them on. Doing this may damage your ears.
(
If the earbuds still aren’t fitting snugly in your ears, try replacing the eartips or the silicone fins.
(
As this product is designed to fit in your ears, your ears may feel tired depending on how the earbuds fit. If you notice any skin
problems after coming into direct contact with this product, stop using this product immediately. If the problem does not
improve, consult with a physician.

keep the earbuds in your ears with just the top part of the small-sized silicone fins. Use caution, as the earbuds may fall out.
(
You can use the earbuds without the silicone fins.
