Delivering a truly customizable mobile audio experience, the LG TONE Free FP5 True Wireless In-Ear Headphones supplies you with the power to optimize your audio and adjust listening to match your environment. When outside or in a noisy indoor setting, such as an office, you can turn on active noise cancellation to filter out distracting ambient sound. A trio of integrated microphones in each earbud work to clearly pickup your voice during hands-free calls, while reducing background noise and cancel echoes.
