Review

The Earaku open-ear earphones utilize air conduction technology to allow listening without blocking the ear canal [S1]. The standout feature is its ultra-lightweight design at 13g, featuring an ear-hook style that prevents interference with glasses and reduces fatigue during extended use [S1]. In terms of power, it supports Type-C fast charging, reaching full capacity in 1.5 hours [S1]. Battery life varies by volume: it offers up to 15 hours at 30% volume, 13 hours at 50%, and 10 hours at 100% volume [S1]. Connectivity is handled by Bluetooth 5.3 with AAC and SBC codec support, and it includes multipoint connection allowing simultaneous pairing with two smartphones [S1]. For calls, it is equipped with ENC (Environmental Noise Cancellation) to suppress ambient noise in windy or loud environments [S1]. While the device features sound leakage suppression technology, the manufacturer notes that sound may leak when volume is set above 80%, advising users to lower the volume in quiet or public spaces [S1].
