【Voltage Compatibility】
Our products are selected to support international voltage ranges (e.g. 100–240V).
However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.

These open-ear wireless earphones don't require ear canals or bone conduction, allowing you to hear your surroundings while listening to music. Large 10mm dynamic drivers deliver powerful, high-quality sound. A gaming mode reduces latency by roughly half. And when you're on a call, the cVc 8.0 noise-canceling microphone eliminates background noise for a clearer voice.
[Hear surrounding sounds without blocking your ear canal] Great for sports, telework, and other times when you want to hear the sounds around you. You can even talk while wearing them. Unlike in-ear earphones, these earphones don't go into your ear canal, so they don't get stuffy inside, making them ideal for those suffering from otitis externa. [Lightweight and pressure-free for long-lasting comfort] The earphones, weighing approximately 10g each, fit gently and become one with your ear. We've paid particular attention to the fit, ensuring stress-free use without worrying about them falling out.
[Long-lasting playback] The earphones offer up to 7 hours of continuous playback. When used with the included charging case, playback time is approximately 20 hours. *Continuous playback time may vary depending on usage environment and method. [Supports aptX and AAC codecs for high-quality sound playback] In addition to the standard SBC codec, the headphones also support aptX and AAC! Enjoy high-quality sound with minimal latency.
[Use without worrying about sweat or rain] Meets IPX5 waterproof rating. You can use it with confidence even during long workouts or sudden rain showers. (Note: This rating only covers water droplets, so it is not suitable for prolonged immersion in water.) [Stable connection and comfort] Compatible with Bluetooth 5.3. Achieves high connection stability with minimal dropouts.
[Touching the button won't stop the music] Touch-sensitive buttons often lead to accidental touches, resulting in accidental operation. This product uses physical buttons to prevent accidental operation. [Wireless charging compatible] If you have a wireless charger (sold separately), you can charge the case by simply placing it on the charger. You can charge the case without the hassle of plugging and unplugging cables. [Technical conformity certification obtained] This product and earphones sold by cheero have been certified by technical conformity, certifying that they comply with the technical standards set forth in the Radio Law, so you can use them safely and with peace of mind.
