The QCY T17 are compact in-ear true wireless stereo headphones designed for a comfortable and reliable listening experience. They feature dynamic drivers that deliver sound across a frequency range of 20 Hz to 20 kHz with a sensitivity of 98 dB, while the Bluetooth v5.3 connectivity ensures a stable wireless link to your devices. To make phone calls clearer in noisy environments, these earbuds incorporate ENC noise cancelling technology that helps isolate your voice from background sounds. Each earbud weighs only 4.2 g and is built with an ergonomic shape including pressure relief holes and soft rubber caps to ensure they sit securely in your ears without causing fatigue. This lightweight design is paired with an IPX4 rating, meaning the headphones are protected against splashes and sweat, making them suitable for workouts or use in light rain. You can manage your music, volume, and calls through intuitive smart touch controls located directly on the buds. Battery performance allows for up to 7 hours of continuous playback on a single charge, which extends to a total of 26 hours when using the included charging case. Because they pair instantly upon removal from the case, these headphones are convenient for people who need a quick transition from their case to their favorite playlist during a daily commute or at the gym.
