Audio adapter cable PREMIUMCORD KJACKCY1-02 — 1x 3.5mm male to 2x 3.5mm female, 20 cm

PREMIUMCORD KJACKCY1-02 is a compact 20 cm audio adapter cable with a single 3.5 mm male plug and two 3.5 mm female sockets. Designed to split a single headphone or line-level output into two outputs, this cable enables simultaneous connection of two headphones or two devices to one audio source. The short length and slim connectors make it convenient for travel, portable media players, smartphones and laptops where a compact, reliable splitter is required.

Advantages

The adapter provides a simple passive splitting solution without the need for power or configuration. Its compact 20 cm length reduces cable clutter and keeps connections close to the source. Precision-molded connectors ensure a stable mechanical fit and consistent signal transfer, while compatible 3.5 mm jacks maintain universal connectivity with most consumer audio devices. The design supports simultaneous listening or routing of line-level signals to two destinations.

Suitable for

• Sharing audio from one phone, tablet or laptop between two pairs of headphones
• Connecting two sets of speakers or headphones to a single portable audio source (line-level)
• Splitting signal for in-car entertainment or airplane headphone use
• Short connections where a compact, travel-friendly splitter is needed

How to use

Insert the 3.5 mm male plug into the audio output of your phone, tablet, laptop or media player. Connect one or two pairs of headphones or audio devices into the 3.5 mm female sockets. Play audio from the source and adjust volume on the source device; if both connected devices have independent volume controls, adjust them as needed for balanced listening. No power or drivers are required; the cable works immediately when connected.

Usage recommendations

For best audio balance, avoid large differences in headphone impedance between the two connected devices. When using with line-level inputs or external speakers, ensure the source output level is appropriate to prevent distortion. Store the adapter in a small pouch when not in use to protect the connectors and maintain cable flexibility.
