[Continue to move forward, never satisfied! ▶Ear cuff earphones] Erssimo has been pursuing wireless earphones that combine innovative design and high performance for many years. Finally, in 2025, the industry's first ear cuff-design earphones that don't block your ears have arrived! These latest 4th generation Bluetooth earphones feature a completely new open-ear audio solution, pioneered by the world. Instead of using bone conduction technology, which transmits sound through vibration, the voice box is located at the top of the ear canal. Instead of inserting the earphones into the ear canal like regular in-ear earphones, they are worn by clipping them onto the earlobe like ear cuffs. This wearing style not only eliminates the vibrations of bone conduction Bluetooth earphones, but also provides a different wearing experience. It also successfully overcomes the shortcomings of traditional TWS earphones, realizing a new listening style. Whether in the city, outdoors, or at the office, you can enjoy music safely and anytime, anywhere while protecting your ears! [Enjoy high-quality earphones with ear cuffs that minimize sound leakage and don't block your ears!] Equipped with a 15mm dynamic driver, they clearly reproduce everything from deep bass to delicate highs. Singing is smooth, the melody is clear, and the sound is full of presence, allowing you to clearly hear even the slightest whisper of a breath. As Bluetooth earphones that do not block your ears, ear cuff earphones not only deliver better sound quality than Bluetooth earphones, but also minimize sound leakage. By using unidirectional conduction technology to deliver sound directly to the eardrum, we have succeeded in minimizing sound leakage. Whether you're in a quiet library or a noisy cafe, you can immerse yourself in your own world while enjoying your favorite music without worrying about the eyes of those around you.

[An encounter with music and fashion] Erssimo earphones do not block your ears, and their ear cuff design ensures comfort and style, making them ideal as a fashion item like earrings. As they are designed not to clip onto your ears, your ear canals do not get steamy, and you can enjoy a comfortable fit and a clean feeling, as if your ears are breathing. The appeal is that they are not tiring to wear for long periods of time. They are also suitable for those who dislike the feeling of blockage or pressure that comes with traditional Bluetooth earphones, wired earphones, and headsets. Furthermore, as they are worn by clipping onto your earlobes from the side, they can be used without getting in the way even when wearing a mask or glasses. [Fully wireless ▶ Faster, more stable, and more convenient!] Equipped with the latest Bluetooth 5.3 chip, it provides fast transmission speeds and stable performance. When the wireless earphones are removed from the charging box, they automatically enter pairing mode, instantly establishing a Bluetooth connection. They maintain a good balance of excellent connection stability regardless of the environment and low latency, ensuring stable and smooth calls even when on the move. The earphones with microphone also feature a microphone noise-canceling function and up to 20 hours of playback time, reducing noise and allowing for long-term use and clear calls when participating in web conferences in cafes, etc. The Type-C charging port allows for easy and fast charging anywhere. The digital LED display makes it easy to see the remaining battery level in the charging case and the charging status of the headset at a glance.
