The Sony WI-C400 was created with user comfort in mind. With a wireless feature, you may move about freely while a neckband keeps you stable. Never miss a smartphone update again thanks to a vibrating notification. The neckband will simply vibrate everytime you receive an update and let you know if you receive a call or text. With the adjuster and stopper, a unique design keeps your cable neatly tucked away in your neckband. Instead of adjusting the cable every time it gets in the way, you can now just focus on what you're doing.
