【"Freedom" in Listening with Open-Ear Headphones】With an open-ear design, ambient sounds naturally enter your ears, so you won't miss surrounding voices even while listening to your favorite music. They're great for telework, allowing you to quickly notice things like a delivery during a call. During walks, housework, and various other situations, content and environmental sounds blend naturally, allowing you to experience the open feeling unique to open-ear headphones. 【Hi-Res Certified, Sound Quality of Open-Ear Headphones Evolves This Far!】GoFree2 has acquired the "Hi-Res Wireless" logo from the Japan Audio Society, achieving sound quality that breaks the mold of open-ear headphones. From deep, resonating bass to gentle, enveloping mid-high frequencies, you can enjoy a well-balanced sound in a relaxed state without blocking your ears. Includes the main unit and case. Please understand that this is a used item. Thank you for viewing.
