The SVEN AP-B650MV is a wireless stereo headset designed for those who need a versatile audio solution for their PC, mobile devices, or media players. These closed-back, over-ear headphones utilize 40 mm drivers to deliver a frequency range from 20 Hz to 20,000 Hz, ensuring a balanced sound experience. Depending on the production date, they feature either Bluetooth 5.0 or the newer 5.3 version, allowing you to move freely within a 10-meter radius of your device. For times when you prefer a wired connection or your battery runs low, a detachable 1-meter 3.5 mm audio cable is included. Constructed from plastic and rubberized materials, the headset weighs approximately 380 g and includes an integrated microphone for clear communication. You can manage your music and calls directly from the earcups using the built-in controls for volume, track switching, and call acceptance, while an LED indicator keeps you informed of the device status. The battery provides up to 40 hours of playback at 30% volume, and newer models utilize a USB Type-C port for charging, while earlier versions use Micro-USB.
