The SVEN E-315B are True Wireless Stereo in-ear earbuds designed for a versatile listening experience. They utilize Bluetooth 5.4 to maintain a stable connection within a 15-meter range, while 13 mm drivers deliver a frequency response from 20 Hz to 20,000 Hz. To help you focus on your audio, these earbuds feature Active Noise Cancellation and a Transparency Mode for when you need to hear your surroundings, complemented by Environmental Noise Cancellation in the microphones to improve call clarity. Constructed from black ABS plastic, the earbuds weigh 40 g and carry an IPX4 rating, making them resistant to sweat and water splashes during workouts or commutes. You can manage your music and volume through touch-sensitive buttons, while the charging case includes an LED display to keep you informed about the remaining battery level. A single charge provides 6 hours of playback, extending to a total of 26 hours when using the 300 mAh case, which recharges via a USB Type-C port. For those who prefer a customized setup, the Smart Life app for iOS and Android allows you to adjust the equalizer, switch noise cancellation modes, or activate a low-latency Gaming Mode. The app also includes a Find My Buds geosearch feature to help locate misplaced earbuds. The package comes complete with the earbuds, the charging case, and a USB-C cable.
