Adjustable ear gels with patented twist-fit Vortex Ribs design deliver a tighter in-ear seal to minimize outside noise seepage. With Active Noise Cancellation activated, environmental noises are now almost completely neutralized, making every note and voice sound clearer, more natural, without losing the details from turning up the volume to maximum. Whether you’re in an airplane, at an outdoor café or on a noisy street, everything sounds as though you’re in the quiet comfort of your personal space.Like all LG TONE Free earbuds, the HBS-FN7 features technology from Meridian Audio, the renowned British audio technology company and LG’s trusted partner in delivering superior sound. Powered by Digital Signal Processing, a technology that Meridian has been perfecting for over 25 years, the LG TONE Free FN7 can recreate a realistic soundstage that simulates the experience of listening to real loudspeakers while also delivering vocals with pristine clarity, completely immersing the listener. Accessible through the LG TONE Free app available for both Android and iOS devices, Meridian’s EQ sound settings provide an elevated listening experience via four customized presets: Natural for a clean, balanced sound, Immersive for a more three-dimensional performance, Bass Boost for extra power and depth and Treble Boost to bring greater clarity to vocals. The LG TONE Free FN7 also delivers fuller, richer bass with high quality silicone-infused drivers, dome featuring a stronger metal layer and denser texture dampers for better resolution of mid-high frequencies.The HBS-FN7 also includes LG’s innovative UVnano charging case, first introduced with LG TONE Free FN6. Using ultraviolet light, the case helps to keep the wearer’s ears cleaner by eliminating 99.9 percent of E. coli and S. aureus bacteria on the earbuds’ inner mesh. New for LG TONE Free FN7, LED lighting on the top of the case makes it easy to monitor charging level and UVnano status.
