Logitech H540 Headset, Black

The Logitech H540 is a wired USB headset designed for use in office and call center environments. Audio is delivered by 40 mm laser-tuned drivers, which work with an internal equalizer that processes the digital signal for balanced sound during calls or media playback. The supra-aural, on-ear design is paired with an adjustable headband for a secure fit. A direct digital connection is established via a standard USB-A plug, requiring no additional software for basic operation on compatible systems.

For voice communication, the headset integrates a boom microphone with noise-filtering technology to reduce the pickup of ambient background sounds. The microphone can be rotated away when not in use. Controls for volume and microphone mute are located directly on the earcup for convenient access. A visible LED indicator confirms when the microphone is muted. The construction features a padded headband and leatherette ear cushions, and the headset weighs 120 grams.
