What it connects
This ESTONE 20503 adapter bridges 6.35mm (1/4 inch) male plugs to 3.5mm (1/8 inch) female jacks. It lets you plug standard headphones or portable players into pro audio gear such as amplifiers. The pack contains two gold-plated units.
Check your ports first
Verify that your source device has a 6.35mm stereo output and that your headphone cable ends in a 3.5mm stereo plug. The adapter is a straight gender changer with no cable, so both sockets must match these exact sizes. A 5 inch pigtail provides a short reach between them.
Steady signal transfer
Gold-plated contacts resist oxidation during long sessions in studio or home setups. The short 5 inch length keeps the signal path direct without adding noticeable resistance. No active electronics means there is no heat build-up or power draw to manage over extended use.

Questions about this item
Does the 2-pack include any cables or do I need to buy a 3.5 mm cable separately?
The pack contains two gold-plated 6.35 mm male to 3.5 mm female adapters only; a 3.5 mm cable must be supplied separately.
Why would I choose the 20503 model over a single adapter?
The 20503 is sold as a two-pack so you can leave one adapter on a studio headphone cable and keep the other on a portable device cable.
What does the 6.35 mm male plug actually fit when I use it with my amplifier?
The 6.35 mm male plug inserts into a standard 1/4-inch stereo jack on amplifiers, mixing desks or professional audio gear.
