Наушники — Koss GMR-545-A-AIR

The GMR-545-A-AIR is a closed over-ear headphone from Koss, built with a wide sensitivity figure and 3.5mm connector for gaming or general use. Koss's GMR range is specifically aimed at gaming, generally featuring a boom microphone and closed-back design intended to combine comfortable long-session wear with reasonable environmental isolation during competitive play.

Position in line

It sits alongside the GMR-540-A-ISO and GMR-545-AIR USB in Koss's GMR gaming-oriented range, distinguished by connector type. As with Koss's broader CS range, the GMR family appears built around a shared acoustic platform differentiated mainly by connector choice between models, making the decision between variants largely a matter of matching to a specific gaming setup's available inputs.

Key specs that matter

Rated response is 15 Hz to 22 kHz. Sensitivity is 103 dB per milliwatt into 35 ohms, an efficient design suited to easy driving from a console, PC or phone without needing dedicated amplification.

Sound and use context

Expect a closed, isolating over-ear character typical of a gaming-oriented design, with high sensitivity for easy drive from a console or PC - the closed design should help block out ambient household noise during competitive gaming sessions, a genuine practical benefit over an open-backed alternative.

Pairing

The 35 ohm impedance and 103 dB sensitivity are easily driven by any phone, console or PC output without needing a separate headphone amplifier.

Alternatives

The GMR-545-AIR USB shares the same driver platform with a USB rather than 3.5mm connector, worth choosing instead for a setup where a direct USB connection is preferred. The GMR-540-A-ISO sits nearby in Koss's gaming range as a related alternative worth comparing on isolation and specific microphone features. Koss's GMR gaming range competes in a crowded market against numerous dedicated gaming headset brands, and buyers should specifically compare microphone quality and boom arm design across competing options, since these gaming-specific features often matter as much as the core acoustic specification for a genuine gaming use case. The 3.5mm connector here should work directly with most gaming consoles and PCs without needing an adapter. Overall this remains a solid, functional choice for a budget conscious gaming setup rather than a premium statement headset. A boom microphone position check before first use also helps ensure clear voice pickup during competitive play.
