INTRODUCTION

    For far too many years, wireless headphones were the “easy” choice, not the audiophile one. They were built for convenience, quick pairing, fewer cables, lighter bags, but they rarely delivered the kind of fidelity that made you stop and really listen. That started to change when Hi‑Res Wireless technology entered the picture. Suddenly Bluetooth audio had the bandwidth, the codec support (LDAC for most), and the headroom it always lacked, giving manufacturers the freedom to tune for nuance instead of just efficiency. Edifier’s ES850NB arrives right in the middle of this shift, aiming to prove just how far everyday listening has come.

    Edifier specializes in premium sound systems that showcase technological innovation and design elegance, delivering outstanding audio experiences through a wide range of headphones, speakers, and music systems, for personal entertainment and professional excellence. Established in May 1996 in Beijing, Edifier is the brainchild of a small group of enterprising music lovers. Over the past 25 years, Edifier has been guided by the “passion for sound” principle, which helped the brand emerge as a world-class designer and manufacturer of award-winning sound systems. Today, Edifier serves audio lovers worldwide through its distributors in over 70 countries, with operations in North America, South America, Europe, the Middle East, and Asia Pacific regions.

    The Edifier ES850NB (currently available in black, brown, ivory and pink colors) come packed with a surprisingly deep feature set for their category, starting with Hi‑Res Audio and Hi‑Res Audio Wireless certification and a pair of 40mm dynamic stereo drivers using titanium‑coated composite diaphragms for clear highs, detailed mids, and solid low‑end performance (20-40kHz frequency response). Wireless quality is handled through LDAC and SBC codec support, while Bluetooth v5.4 and multipoint connectivity keep the connection stable and flexible across devices. Edifier’s upgraded hybrid ANC system can reduce ambient noise by up to -45 dB, complemented by over‑ear passive isolation for a more immersive experience. Battery life is another standout delivering up to 92 hours with ANC off, or around 53 hours with ANC on, making the ES850NB genuinely week‑long headphones for daily use. Comfort and practicality are also part of the package, with skin‑friendly leatherette cushions, a light 265g frame, foldable design, and an included travel case. Add in AI‑assisted call noise reduction, Touch‑to‑Chat, wired USB‑C audio support, and app integration through Edifier ConneX (Android) and TempoHub (iOS), and the ES850NB rounds out as a feature‑rich, modern wireless ANC headset built for everyday versatility.
