Verdict

The Energy Sistem Office 6 is a lightweight, on-ear wired headset featuring a noise-cancelling unidirectional microphone and an inline controller for quick volume and mute adjustments. Designed for professional environments, it includes a 150cm cable with a 3.5mm jack connector, 30mm drivers with a 20Hz-20kHz frequency response, and synthetic leather earpads for long-wear comfort. Its main pros are the clear voice capture and plug-and-play simplicity, though cons include a lack of USB connectivity options and limited passive noise isolation due to the open on-ear design.
