SurroundWave 8D Audio Processing Technology & 14.2mm High-Quality Drivers: The 2024 enhanced OWS wireless earphones YYK-Q16 feature an upgraded all-metal case for a more comfortable fit. "OWS" stands for "fully open yet inaudible sound solution." These open-ear earphones feature a compact, highly integrated solution designed for audio, utilizing multiple sound source points and dynamically monitoring and calculating to generate a synthesized sound source. Dynamic phase adjustment suppresses external noise, resulting in high-quality sound. The SurroundWave sound processing technology processes the direction, distance, and depth of the audio signal, providing a more three-dimensional and realistic musical experience. The large-aperture 14.2mm drivers deliver excellent balance from bass to treble, providing superior HIFI sound quality without blocking ears, delivering a clean, three-dimensional sound, significantly enhancing listening enjoyment and immersion.
[Advanced open-ear design with industry-leading Bluetooth 5.4 technology] These completely wireless earphones leave your ears unobstructed, allowing you to hear surrounding sounds even outdoors for greater safety. The open design prevents damage to the ear canal and ensures comfortable listening, even when worn for extended periods. Compared to current Bluetooth 5.1 and 5.3 earphones, OWS Bluetooth earphones utilize innovative Bluetooth 5.4 technology, resulting in lower power consumption, improved stability, and reduced sound latency. They also boast three times the transmission depth, six times the transmission distance, and ten times the transmission capacity. At the same time, the wireless earphones offer a stronger signal, a longer transmission distance of 15m, and are compatible with iOS and Android devices. They're ideal for exercise, gaming, commuting, and more.
Long Playtime! Up to 60 Hours of Continuous Use with LED Display: Today's consumers are constantly seeking longer earbud usage times and shorter charging times. To that end, our engineering team has been constantly improving our earbuds! These Bluetooth earbuds offer up to 10 hours of playback time on their own (5 hours in the left ear + 5 hours in the right ear, when using both earbuds simultaneously), and up to 60 hours of playback time when used with the charging case. A quick 10-minute charge extends playback to 1.5 hours! This eliminates the need for frequent charging, making them perfect for commuting, business trips, and conference calls. The charging case takes approximately 1.5 hours to fully charge. To ensure a clearer understanding of the remaining charge in the charging case, an LED display has been added, allowing you to check the remaining charge every time you use it. The charging case also features a matte spray coating, making it less susceptible to fingerprints and enhancing its aesthetics.
Equipped with directional sound transmission technology and IPX7 sweatproof and waterproof rating: Equipped with directional sound transmission technology, sound transmission is concentrated at the sound hole, more effectively reducing sound leakage. Furthermore, by intelligently identifying ambient sounds while maintaining directional transmission, these headphones offer a unique advantage by allowing you to hear your surroundings even when exercising outdoors. Not only can you hear potential hazards better than with in-ear headphones while running, but you can also stay connected to the world around you. Increased peace of mind! These sports earphones are IPX7 sweatproof and waterproof, so you can rest assured they will not break down even if you're sweaty or caught in heavy rain. These headphones are perfect for everyday use, the gym, or running.
[Automatic Pairing & Malfunction Prevention, Ergonomic Ear-Hook Design] The wireless headphones automatically pair when you remove the ear-hook earbuds from the charging case. They will automatically power off when you return them to the charging case after use. After the initial pairing, to reconnect, simply open the lid, remove them from the charging case, and they will automatically connect to your device instantly. The earbuds feature an ergonomic design that doesn't block your ears, and the ear hooks are made of extremely soft silicone rubber, allowing for flexible positioning and a perfect fit for ears of various shapes and sizes. OWS earbuds combine the industry's latest sensor technology to ensure sensitivity and effectively prevent malfunctions. They feel comfortable even with long hair or jewelry. The highly sensitive touch buttons allow you to play and pause music, answer and end calls, and more without having to take out your smartphone. A light touch on the earbuds provides a "tap" feedback, providing a comfortable operation experience. The earbuds can also be used separately, allowing for single or binaural use. You can use both ears when listening to music and one ear when making calls, so you can use it anywhere and in any situation.
