PANASONIC / RB-C10-K Black

＜＜Jun 2026 New Product！＞＞ The "RB-C10" is a pair of truly wireless earbuds designed around the concept of "adorn[ing] sound beautifully." Featuring an open-ear "ear-cuff" style that eliminates pressure, they deliver direct, high-quality audio via 11mm drivers.

■ "Open-ear" listening and a comfortable fit
・ Featuring an ear-cuff design that clips onto the ear without blocking the ear canal, these allow you to comfortably enjoy audio while remaining aware of your surroundings. Because they do not insert into the ear canal, they eliminate the pressure and feeling of confinement often associated with standard earphones. They fit naturally and are unlikely to interfere with glasses, mask straps, or your favorite accessories.

■ "Sound Leakage Reduction Mode" for consideration of others
・ Equipped with a "Sound Leakage Reduction (Polite) Mode," these provide peace of mind in quiet settings like libraries or elevators, as well as in crowded spaces like trains. This mode minimizes the sound leakage often associated with open-ear designs, allowing you to comfortably enjoy your favorite content anywhere while maintaining privacy.

■ Large-diameter 11mm driver for direct sound delivery
・ Uses a unique driver design that directs sound straight into the ear canal. Despite the open-ear style, sound is transmitted directly without compromising quality. The large-diameter 11mm driver delivers powerful, rich audio, allowing you to fully enjoy your music while naturally letting in ambient sounds.

■ ENC function for clear voice transmission in noisy environments
・ The microphone features ENC (Environmental Noise Cancellation) technology. It intelligently filters out unwanted ambient noise from the audio input. Even in noisy settings like offices or busy city streets, it significantly reduces background noise, ensuring your voice comes through clearly to the person on the other end.

■ Lightweight design (approx. 5.5g per ear) and unique "Airy Fit"
・ Designed to be worn like an accessory, each earbud weighs just approximately 5.5g. Additionally, the bridge section utilizes a flexible shape-memory alloy. The "Airy Fit" design evenly distributes pressure on the ears to minimize strain, ensuring supreme comfort that remains pain-free and natural even during extended use.

■ Reliable long battery life and rapid charging—from morning to night
・ Features a long-lasting battery that provides approximately 7 hours of continuous playback on the earbuds alone, extending to a maximum of approximately 26 hours when using the charging case. It also supports rapid charging, offering about 60 minutes of use from just a 15-minute charge, so you can use them with confidence from your morning departure until you return home at night without worrying about battery levels.

■ Convenient multipoint connection and physical buttons for business use
・ Supports multipoint connection, allowing simultaneous pairing with up to two devices (such as a smartphone and PC) and seamless switching to answer incoming calls while watching videos. Physical buttons with a satisfying tactile click are used for controls; this prevents accidental operation caused by hair or hands brushing against the earbuds, ensuring stress-free use.

■ A premium design beautifully accented with a pearl motif
・ A sophisticated design that embodies the concept of "adorning sound beautifully," featuring a drop-pearl shape and an elegant, glossy pearl finish. The soft color variations blend naturally with your skin, creating a look that feels like a natural extension of yourself. The earbuds are IPX4 splash-proof, making them safe to use in the kitchen or during sports, and they support independent use of either the left or right earbud.
