The DELTACO HL-21 is a wired, on-ear headset designed for professional and general computer use. It is equipped with 30mm stereo drivers that cover a frequency range of 20 to 20,000 Hz, with a sensitivity of 108 dB. The lightweight 47g construction and adjustable headband are intended to provide a comfortable fit during extended periods of use. Connection to a computer or other compatible device is established via a standard 3.5mm audio jack, and the integrated 2-meter cable offers sufficient length for most desktop setups.
This headset incorporates a boom-style microphone positioned for direct voice pickup during calls and online meetings. The microphone captures audio within a frequency range of 30 to 16,000 Hz. For user convenience, the cable features an in-line control unit that allows for simple rotary volume adjustment and includes a dedicated switch to mute the microphone.
