The flexible silicone neckband and two ear hooks provide ergonomic support for maximum support and a comfortable, secure fit, even while walking or working out. The SoundFold J135's open-ear design allows you to fully hear your surroundings while focusing on your workout. Furthermore, the open-ear listening style is ideal for those with sensitive ears or sports enthusiasts who wear them for long periods of time, reducing ear fatigue. "Immersive Listening Experience" - These wireless earbuds feature extra-large 27mm drivers, roughly twice the size of comparable sports earbuds in the industry, delivering a 4.3x wider soundstage. Additionally, LE Audio, AAC, and SBC decoding technology allow the speakers to float in front of your ears for a pressure-free listening experience, making you feel like you're floating while running. The DSP amplifier also optimizes sound balance, delivering a powerful blend of bass and clear mids and highs for a truly immersive audio performance. "Sweat-resistant and durable" - Did you know that salt and oils contained in sweat can seep into earphones and cause malfunctions? To create truly sports earphones, Earaku uses high-density nano-coating technology and reinforced UV resin, and has undergone a 62-hour salt spray test, exceeding industry standards. The incredible IPX6 waterproof and sweat-resistant performance completely blocks sweat from entering even during intense exercise. Perfect for a variety of activities, including running, marathons, jogging, trail running, mountain climbing, and sports, as well as on the train, during your commute, and for Zoom/web conferences. (Please refrain from wearing these earphones while swimming.) 23 Hours of Continuous Playback and Low Latency Wireless - Don't stop your workout, don't stop your music! This open-ear headset features a built-in 250mAh battery that can be fully charged in approximately 2.5 hours. With up to 23 hours of music playback, you can exercise without worrying about your music cutting out. Additionally, Earaku sports headphones are equipped with the industry-leading Bluetooth 5.4 chip, which significantly improves performance over previous versions in terms of transfer speed, connection stability, and sound reproduction. This allows for an easier, faster, and more seamless Bluetooth connection experience than ever before. (Actual usage time may vary depending on the device and volume level.) "Simultaneous connection to two devices" - These open-ear headphones support multipoint connection, allowing simultaneous connection and standby for two devices, such as a PC and smartphone. You can answer or talk on your smartphone during an online PC meeting, play music on your smartphone while commuting, or hold an online PC meeting after arriving at work, all without having to switch Bluetooth connections. Multipoint Support: Supports multipoint connection, allowing simultaneous connection to two devices. "Easy Physical Button Operation & Reliable Guarantee" - These Bluetooth earphones use physical buttons instead of touch controls, allowing you to intuitively perform basic operations such as playing and pausing music and answering calls. They combine sound quality and functionality, making them ideal not only for enjoying music but also for switching between songs while exercising.
