2. Main Features
Full Digital Noise Cancelling Compatible
Microphones located in each earphone pick up ambient noise, which is digitally processed by the Xperia device to cancel out the noise. Noise is reduced by up to approximately 98%.
13.5mm Large Diameter Driver
Equipped with a large driver for canal-type (earplug type) earphones. Achieves high sound resolution and reproduces everything from rich bass to clear treble.
Battery-less Design
Noise cancelling processing is done by the smartphone, and power is also supplied from the smartphone, so the earphones themselves do not require charging.
Combines Fit and Sound Isolation
The shape that fits deep into the ear and the highly sealed earpieces ensure physical sound isolation.
Precautions
No call function
The microphone is for noise collection only and cannot be used for calls. When receiving a call, you will need to speak using the microphone on the smartphone itself.
5-pole Terminal Exclusive
The noise cancelling function only works on models equipped with a Digital Noise Cancelling Compatible 5-pole Jack, such as the Xperia Z2 and later.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
