The Edifier K800 is a wired on-ear headset designed for clear communication during online learning, business meetings, and gaming. It connects via a USB Type-A port and features an independent external sound card that improves audio quality during the digital-to-analog transition. The sound is delivered through Japanese black voice coil drivers with a frequency response of 20 Hz to 20 kHz and an impedance of 32 Ohm. For voice capture, the headset uses a single-direction noise-canceling microphone that can be rotated 120 degrees to fit your preferred position. Comfort is handled by memory foam earmuffs and an adjustable headband, ensuring a secure fit for various head sizes. A long 2.8-meter cable provides plenty of room to move around your workspace, while integrated smart volume control technology helps protect your hearing during extended use.
