USB K815

The USB K815 is a wired over-ear headset aimed at online education, voice calls and everyday entertainment. It connects with a USB-A plug and works plug-and-play, with a separate audio chip built into the cable that handles decoding of the digital and analog signal.

Sound is produced by polymer diaphragms with Daikoku wire voice coils. Volume-limiting technology holds the sound pressure level down to protect hearing, so the headset is positioned as suitable for children. The long-rod microphone rotates through 120 degrees and uses noise cancellation to keep speech clear in noisy rooms.

For comfort, the headband is made of flexible PP material and adjusts to different head sizes. Soft inner ear cushions and a four-point pressure distribution design reduce pressure during long wear. A 2.8 m cable with optimized cores is intended to resist bending and stretching.
