Once headphones can last up to 7 hours of use (at 80% volume), and the charging case allows you to charge them 3-4 times. This allows the user to enjoy a total of up to 31 hours of continuous battery life while wearing two earbuds at the same time. This ensures long-lasting use of the device without the need for frequent charging, which is ideal for both everyday use and travel. Equipped with a large dynamic speaker with a 13 mm diaphragm, the device provides a fuller and more detailed sound. With this speaker, music sounds more impressive because it is able to reproduce a wider range of tones and provide a richer audio experience. This is a perfect solution for people looking for a deeper and more immersive musical experience. Thanks to the improved BT 5.3 chip, lower power consumption and a stronger and more stable signal, you can enjoy excellent sound quality within a radius of up to 12 meters. This means greater freedom of movement without having to hold the device close to the sound source. Now you can listen to music or make phone calls with high sound quality, even when you are at a distance from your device. With a finely polished appearance, the earbuds fit perfectly into the ear canal for comfortable wearing. Their lightweight design makes them virtually unnoticeable during use, and a single earbud weighing only 3.8 g is 9% lighter than standard earbuds. This means that they can be worn for a long time without feeling any discomfort, which is especially important when listening to music or making phone calls for a long time. When you open the charging case, the headphones will automatically reconnect to the last connected device. This feature provides convenience and time-saving by eliminating the need to manually pair every time you want to use the headphones. Smart touch controls let you easily answer phone calls, play songs and wake up Siri. Thanks to this modern solution, the user can quickly and intuitively manage the headphone functions without having to reach for the phone. Simple touch gestures allow you to use the device smoothly and comfortably in any conditions, providing full control over music and calls.
