LG's prior FN6 earbuds were tuned by Meridian to deliver the best soundstage possible in such a small package. The HBS-FN7 builds upon that foundation. Using three microphones, they offer active noise cancellation to eliminate background noise while still offering 5 hours of battery when activated (and up to seven with it off). The charging case boosts maximum battery life to 21 hours and has a built-in UVnano light that kills up to 99.9 percent of bacteria on the 'phones. Available in South Korea now, they'll be available in other markets later this year.
