Four small black 3.5mm to quarter-inch headphone adapters

RODE Microphone

RODE Microphone HJA-4 3.5mm TRS to 1/4" Headphone Adapters, 4-Pack

SKU CH-0ZRM-ZV0ZQ

Four adapters convert 3.5 mm headphone plugs to 1/4" sockets for professional audio gear

  • Four adapters included for multiple headphones
  • 5 mm to 1/4" TRS conversion for pro audio gear
  • Compact 45 x 10 x 10 mm size fits tight jack spacing
  • Straight male and female connectors ensure secure signal path
  • Designed for RDECaster Pro and AI-1 compatibility

Four-Pack 3.5 mm to 1/4" TRS Adapters

The Rode HJA-4 supplies four straight adapters that convert a 3.5 mm TRS male plug to a 1/4" TRS female socket. Each unit measures 45 x 10 x 10 mm and is built for reliable signal transfer in studio and portable setups. The pack format keeps spares on hand for multi-headphone sessions or cable bags.

Suited for consumer headphones on pro gear

These adapters let owners of 3.5 mm headphones connect directly to equipment with 1/4" sockets such as the RDECaster Pro or AI-1. They are not for users who need balanced XLR conversion, angled plugs for tight racks, or a single premium adapter rather than a multi-pack.

Handles four simultaneous headphone connections

The four adapters comfortably serve a small recording group or a podcaster with backup pairs. They run out when a session requires more than four concurrent 3.5 mm headphone feeds or when the source device lacks 1/4" outputs altogether.

Questions about this item

Does my headphone cable need a 3.5 mm TRS plug to use these adapters?

Yes, each adapter has a 3.5 mm TRS female socket, so the headphone cable must end in a matching 3.5 mm TRS male plug.

Will the 1/4" TRS male end fit the headphone output on my RODECaster Pro?

The 1/4" TRS male connector is designed for the larger headphone sockets found on the RODECaster Pro and the AI-1.

How can I confirm the adapters are passing audio correctly after I plug them in?

Insert a headphone with a 3.5 mm plug into the female socket, connect the 1/4" end to your device, then play audio and listen for clear stereo sound on both channels.
