The SVEN AP-B580MV are wireless over-ear headphones designed for a versatile listening experience across your PC, laptop, or mobile devices. They utilize Bluetooth 4.1 to provide a wireless connection within a 10-meter range, though you can also plug in the included 1.2-meter cable using the 3.5 mm jack if you prefer a wired setup. Inside, 40 mm drivers cover a frequency range from 20 Hz to 20,000 Hz, delivering balanced sound with a sensitivity of 102 ± 3 dB. These closed-back headphones are built from a combination of plastic and rubberized materials, keeping the total weight at a light 180 g for comfortable extended wear. You can manage your audio directly via the integrated volume and track controls, while the built-in microphone allows for clear communication. The internal battery provides up to 12 hours of playback and recharges through a standard Micro-USB port, making them a practical choice for those who need a reliable headset for both media consumption and calls throughout the day.
