Product details

Overview

Meet the MillSO 1/4 to 3.5mm headphone adapter, a versatile stereo connector designed to bridge devices with different jack standards. By converting a standard 3.5mm female to a 6.35mm male plug, it helps you link equipment like smartphones, tablets, headphones, keyboards, amplifiers, and speakers without fuss.

Long reach for flexible setups

The 16-foot extension provides ample room to arrange gear in live rooms, studios, or home theaters. The durable PVC jacket resists bending, keeping your workspace tidy as cables cross the room.

Signal quality you can count on

Gold-plated 24K connectors deliver stable contact, while tin-plated oxygen-free copper wiring supports faithful signal transfer. A rugged metal housing adds durability, and quadruple-layer shielding minimizes external interference for a clear stereo image.

Wide compatibility

The combination of a 3.5mm TRS female jack and a 6.35mm male plug broadens compatibility with amps, keyboards, mixers, and headphones that use larger jacks. Note that this adapter passes stereo audio and does not carry microphone signals.
