Experience real wireless stereo like never before with the LG Tone Free, featuring wireless earbuds that charge while they are docked in the neckband, always ready for immediate use. The neckband not only provides extra battery power and vibration alerts for incoming calls but it also provides a secure place to hold the earbuds when not in use, making them far less likely to be misplaced.
