Roa International Co., Ltd. (located in Shinjuku, Tokyo; CEO Ally Won) is launching the 'CuffAir,' an ear-cuff style open-ear wireless earphone that combines lightweight comfort with a sophisticated design, under the mobile accessory brand 'HACRAY.' This product features multi-point connectivity for two simultaneous devices and employs a large 11mm driver. Additionally, it comes equipped with a special silicone cover that reduces sound leakage by suppressing sound dispersion, delivering high-quality audio directly to the ear. Sales have commenced on the official online store: https://www.mycaseshop.jp.
Product Features:
● Open-Ear Cuff Design: The ear-cuff structure and flexible TPU material ensure a gentle fit, reducing pressure and discomfort for long-term wear. Suitable for everything from daily use to sports.
● 3D Sound from 11mm Large Drivers: Optimized acoustic design with 11mm drivers provides powerful bass and a wide soundstage, offering a three-dimensional, immersive listening experience.
● Sound Leakage Suppression with Special Silicone Cover: A dedicated silicone cover on the speaker unit minimizes sound dispersion, focusing the audio towards the ear while reducing leakage in public spaces like trains or cafes. Despite being open-ear, it allows users to focus on sound without worrying about their surroundings. It can be stored in the case while wearing the cover.
● Physical Buttons for Mistake-Free Operation: Tactile physical buttons prevent accidental inputs often seen with touch controls. Different colors for left and right buttons allow for quick identification and prevent incorrect placement in the case. Shown are physical buttons (left) and the back of the earphone (right) color-coded for both sides against the sleek black finish.
● Flexible Fit with Ultra-Fine Memory Wire: Uses a 0.6mm diameter nickel-titanium shape-memory wire that has cleared 10,000 expansion tests. It maintains a stable fit without deformation, complemented by high-quality TPU and a metallic finish for a sophisticated, premium look.
● Multi-point Connection for Two Devices: Connect to two devices simultaneously, such as a smartphone and a PC, allowing for seamless switching without re-adjusting Bluetooth settings.
● IPX4 Water Resistance: Resistant to sweat and light rain, making it safe for commuting and exercise.
● Stable Wireless Connection via Bluetooth: Uses the latest communication technology for a stable, interruption-free wireless experience.
● Long Battery Life Up to 24 Hours: Provides approximately 7 hours of playback from the earphones alone and up to 24 hours total when used with the charging case.
