Four-input HDMI 2.0 switch with audio extraction

This ESTONE OZQ4 unit accepts four HDMI 2.0 sources and routes one to a display at up to 4K@60Hz. It also extracts audio through optical Toslink and 3.5 mm stereo outputs, letting users feed external speakers or a soundbar without relying on the TV’s own connections. An IR remote and automatic signal detection handle source selection.

Passive operation with USB power and no fan noise

The switch draws power from an included USB cable, so it adds no audible fan noise and negligible heat to an entertainment setup. With a maximum bandwidth of 18.5 Gbps it passes HDR and 4K@60Hz signals without active cooling, keeping the installation silent in normal use.

Compact metal chassis

The black enclosure measures 5.91 x 2.36 x 0.79 inches and weighs 11.9 ounces, fitting easily behind a TV or inside a cabinet. Four HDMI inputs and one HDMI output sit alongside the optical and 3.5 mm audio jacks, while front LEDs indicate the active source for quick visual confirmation.

Questions about this item

How do I install the OZQ4 switch and which step is often missed?

Connect up to four HDMI sources to the four input ports, connect the output port to the display, attach the USB power cable to a 5 V USB source, then use the IR remote or front button to select the active input; the step often missed is providing USB power because no power adapter is included.

What maintenance will the OZQ4 need later?

The only replaceable part is the IR remote battery; the unit itself has no fan, filter or user-serviceable components.

What limit appears first during sustained 4K@60 Hz use?

The 18.5 Gbps bandwidth ceiling is reached at 4K 60 Hz RGB 4:4:4, so any higher colour depth or refresh rate would require a faster link.
