## Earaku SoundClip Ear Cuff Wireless Earphones Review The Earaku SoundClip is an open-ear wireless earphone that takes a distinctive approach to audio — it clips onto your ear like a piece of jewelry rather than sitting inside your ear canal. Designed for users who want to stay aware of their surroundings while enjoying music, the SoundClip combines an accessory-like aesthetic with serious audio technology. ### Design and Comfort The SoundClip features an ear cuff design that clips onto the cartilage of your ear, leaving the ear canal completely open. Each earbud weighs just 5.3 grams, making them remarkably lightweight for extended wear. The C-shaped bridge uses a nickel-titanium shape memory alloy wire, which provides both durability and flexibility to accommodate various ear shapes. This design philosophy aims for what Earaku calls "zero wearing sensation," whether you're working from home all day or engaging in vigorous exercise. ### Sound Quality At the heart of the SoundClip's audio performance is a 12.8mm oversized driver paired with Earaku's proprietary Malleus AELC algorithm technology. This algorithm automatically adjusts the output levels of high and low frequencies based on the actual input source and output sound pressure, optimizing the volume balance across three frequency bands. The DSP amplifier function further refines the balance between bass, midrange, and treble while digitally identifying and removing noise within the earphones. The SoundClip supports AAC and SBC codecs, helping to minimize audio-visual latency for movies and gaming. ### Sound Leakage Prevention A common concern with open-ear designs is sound leakage, and Earaku addresses this with their Sound Direction technology. The internal structure and algorithms control the directionality of sound, delivering audio directly to the ear canal and eardrum. A rear speaker helps regulate air pressure within the housing, and a sound cavity design works to effectively suppress sound leakage, maintaining user privacy despite the open-ear form factor. ### Connectivity and Features The SoundClip runs on Bluetooth 5.4, offering stable connections and low latency. Multipoint connectivity allows simultaneous pairing with multiple devices — you can listen to music on your PC while seamlessly switching to take a phone call on your smartphone. ENC (Environmental Noise Cancellation) technology for calls reduces external noise, ensuring clear voice communication even in noisy environments. Touch controls allow intuitive operation for play/pause, track skipping, and call management. Both single-ear and dual-ear modes are supported, letting you share one earbud with a friend or use both for a full stereo experience. ### Battery and Durability The SoundClip boasts an impressive 48-hour total playback time (with the charging case), making it suitable for extended use without frequent recharging. With an IPX5 water resistance rating, the earphones can handle sweat and light rain, making them suitable for running, outdoor workouts, and other active scenarios. ### Verdict Priced at ¥9,978 on Amazon.co.jp, the Earaku SoundClip offers a compelling package for anyone seeking an open-ear listening experience. With its accessory-like ear cuff design, proprietary audio optimization technology, long battery life, Bluetooth 5.4, and multipoint connectivity, it targets users who value situational awareness alongside quality audio — whether during remote work, commuting, exercise, or household chores.
