Slim 3.5 mm stereo extension

This 3.3 ft cable adds reach between a portable device and powered speakers or headphones. The male-to-female 3.5 mm connectors carry stereo audio without signal conversion. Its 0.3 in diameter lets it pass through tight openings where bulkier plugs cannot fit.

28 AWG conductors with nickel-plated contacts

The 28 AWG wire gauge provides flexibility for desktop routing while maintaining stereo fidelity at this length. Nickel plating on both 3.5 mm plugs resists oxidation during repeated insertion cycles. The PVC jacket protects the conductors from everyday abrasion.

Male-to-female layout frees the source device

The extension plugs into the player or phone, then accepts your existing headphone or speaker cable. No additional adapters or power are required. The slim 8.5 mm connector housing clears recessed ports on slim cases and protective covers.

Questions about this item

Will the 3.5 mm male plug fit alongside other cables in a tight headphone jack on my older phone?

The connector body is 8.5 mm wide and 8.5 mm high, so it sits flush in most recessed jacks without blocking adjacent ports.

How can I verify the cable passes stereo audio correctly after plugging it in?

Play a track with distinct left and right channels; both ears should receive sound and the inline remote or microphone on your headset will stay functional through the female jack.

Does the package include any adapters or is the 3.5 mm male-to-female cable the only item?

Only the 3.3 ft 28 AWG extension cable with nickel-plated 3.5 mm connectors is supplied; no extra adapters or couplers are included.
