Connect your headphones
Convert a 3.5 mm headphone plug for use with a larger ¼-inch headphone socket. Keep your existing headphones when moving between compatible devices. Check the fit on the specified microphone and make a short spoken test before recording, keeping its position and input level consistent.
Four adapters in one pack
Equip several headphone connections or keep adapters ready across your recording setup. The HJA-4 is supplied as a pack of four. Check the fit on the specified microphone and make a short spoken test before recording, keeping its position and input level consistent.
Made for your audio setup
RØDE recommends HJA-4 for RØDECaster Pro and AI-1 headphone connections. The studio equipment and cables in the photo illustrate use and are sold separately. Check the fit on the specified microphone and make a short spoken test before recording, keeping its position and input level consistent.
Change Plug Size Without Changing the Signal
The adapter changes the physical headphone connection from 3.5 mm to a quarter-inch headphone socket. It does not add amplification, turn a normal stereo cable into a balanced cable or create a microphone input. Choose the listening output for the headphones’ actual requirements.
Keep Spare Adapters with Shared Equipment
A four-adapter pack can serve several headphone outputs or keep a spare near the recording desk. Check whether the headphones already include an adapter before adding another pack, and keep each connector with the equipment used in that particular listening arrangement.

Check the Complete Listening Connection
Fit the adapter to an appropriate headphone plug, then connect it to the matching headphone output. Keep recording gain separate from listening volume and start at a low playback setting. A headset microphone requires its own compatible input path; this is a listening adapter.
Match Both Ends of the Signal Route
Choose the connectors, signal type and cable length for the equipment at both ends. A passive lead does not add an audio interface, power supply or a different signal protocol; confirm the input function before ordering. Compare related options such as RØDE XLR3M Premium XLR Cable, 3M Length or Elgato Chat Link Pro Audio Adapter Cable, 2.5m, keeping the exact model and configuration in the decision. For the wider setup, explore RØDE PodMic Dynamic Podcasting Microphone, XLR and check the connection, size or mounting requirements before pairing accessories. Browse the RODE range at AX for more choices.
