DELTACO HL-57 Headset, Black

The DELTACO HL-57 is a wired, over-ear headset intended for office and computer applications. It establishes a connection via a 2-meter USB Type-A cable, which provides a direct digital audio signal from the host device. The headset is equipped with 40 mm drivers that produce stereo sound across a standard frequency response range of 20 Hz to 20,000 Hz. Its closed-back, over-ear design features large earcups intended to cover the ears completely, providing a degree of passive sound isolation in a typical work environment.

For voice communication, the headset integrates a flexible boom microphone with an omnidirectional pickup pattern to capture sound from multiple directions. The microphone's position can be physically adjusted for optimal voice clarity during calls. A controller is integrated into the cable, offering direct access to volume adjustments without interacting with system software. The unit weighs 220 grams and utilizes a standard headband construction, a design focused on stability during periods of extended use at a desk.
