LG Touts Meridian Audio, Bacteria-Killing Technology in Latest True Wireless Earbuds

Meridian audio technology and a bacteria-snuffing charging case are differentiators in LG’s Tone Free true wireless earbuds ($149), announced Thursday. The UVnano charging case is said to kill 99.9% of bacteria on the earbuds’ speaker mesh during the powered charging cycle using an ultraviolet light test protocol developed at UL. Meridian’s headphone spatial processing technology creates a soundstage that simulates the experience of listening to loudspeakers, said the company.
