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.
(
“Playing back sound according to your surroundings”(p.27)
ADVANCED ANC
This feature analyzes the playback sound and outside noise, and reduces only the noise while maintaining
the playback sound quality. By reducing noises from outside such as trains, buses and so on, you can absorb
yourself in the music without the need to raise the volume too much.
(
“Playing back sound according to your surroundings”(p.27)
LISTENING CARE -Advanced
This product features LISTENING CARE -Advanced, 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.
LISTENING OPTIMIZER
This analyzes the audio in real time and adjusts the sound quality to best match how this product fits on your
ears and your ear shape.
GAMING MODE
Enabling this function helps improve latency when you are watching a video or playing a game that is
affected by lag or delay.
6
Introduction > Advantages of this product
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 the 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.25)
Google Fast Pair
You can easily pair this product with your Android™ smartphone. Pairing is supported with Android devices
than run Android OS 6.0 or later, or Google Play 11.7 or later.
(
“Pairing for the First Time”(p.17)
Smartphone support
You can use this product to talk on the phone and start up the voice assistant while connected to 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, ADVANCED ANC, LISTENING CARE -Advanced, LISTENING
OPTIMIZER, GAMING MODE, In-Ear Detection 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.
