Product Overview
Advantages of this product
This product is a set of wireless earphones that connect to Bluetooth devices such as a portable music player
or smartphone.
High-definition playback of sound from Bluetooth devices
This product supports the Qualcomm aptX™ and AAC codecs.
Supports Qualcomm TrueWireless™ Stereo Plus (TWS+)
This product supports TrueWireless Stereo Plus-compatible Bluetooth devices, offering more stable
connectivity.
Active noise cancelling (ANC)
This feature reduces noises from outside such as from trains, buses and so on. This helps you to get more
absorbed in the music, while eliminating the need to raise the volume too much.
AMBIENT SOUND function
The sounds around you will be mixed together with the playback sound. This feature is convenient when you
want to listen to music while being careful of what is going on around you, such as while you are walking,
when you want to briefly talk with someone and so on.
LISTENING CARE feature
This product features LISTENING CARE, which lets you enjoy rich sound quality even at low volumes.
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.
Wireless charging (Qi standard) support
The charging case can simply be placed on a Qi-standard wireless charger to charge.
Smartphone feature 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: Headphones Controller
Use the Headphones Controller app to configure more detailed settings.
