Product Overview > Advantages of this product
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 over the air.
High-definition playback of sound from Bluetooth devices
This product supports the Qualcomm aptX™ Adaptive and AAC codecs.
ADVANCED ANC feature
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.
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.
LISTENING OPTIMIZER feature
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.
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.
