## Description

For connecting a laptop, PC, or smartphone with a 3.5mm audio output to equipment with two 1/4-inch inputs, the SiYear Y-splitter provides a direct stereo-to-dual-mono connection. Its 10 ft cable gives you room to route audio between devices while keeping the left and right channels on separate plugs.

The cable can also combine two 1/4-inch mono signals into one 3.5mm stereo connection, making it useful for different audio routing setups.

## Key points

The 3.5mm TRS end carries a stereo signal, while the two 1/4-inch TS ends provide separate left and right unbalanced mono connections. Connect a computer or phone with a 3.5mm output to a mixer, amplifier, AV receiver, speaker, or other equipment with dual 1/4-inch inputs. For example, this layout can link a laptop’s headphone output to the two inputs on an audio mixer without using a pair of separate adapter leads.

The cable supports the reverse arrangement as well: two 1/4-inch mono signals can be combined into a single 3.5mm stereo connection. This makes the Y design useful when choosing between a stereo output split and a dual-mono-to-stereo connection, rather than using a cable with only one 1/4-inch plug. Its 10 ft length allows flexible placement of the connected devices.

4N OFC wire, high-density shielding, and aluminum-foil shielding are designed to help reduce EMI/RFI interference during audio transfer. Polyethylene insulation supports high-frequency response, and the 6.0mm cable is described as strong, flexible, and durable for everyday routing between audio components.

## Everyday use

Use the cable to connect a 3.5mm-equipped laptop or smartphone to a mixer or amplifier with two 1/4-inch inputs, or to route audio between compatible home audio and recording equipment. In a desk setup, the extra cable length can help position a computer away from the mixer while keeping the left and right connections distinct. It also works for interconnecting other audio devices that use the stated connector types.

## Usage tips

For stereo output from a 3.5mm source, connect the TRS mini plug to the source and the two 1/4-inch plugs to the corresponding left and right inputs on the receiving equipment. When combining two mono signals, connect each 1/4-inch plug to its respective signal source and the 3.5mm plug to the stereo input. Match the cable’s connectors to the jacks on your equipment before setting up the audio path.

## Buying verdict

Choose this SiYear cable when your setup needs a 3.5mm stereo connection and two 1/4-inch mono connections in one Y-shaped lead. The reversible signal-routing use, 10 ft reach, and interference-shielding construction make it a practical fit for connecting a computer or phone with a 3.5mm output to mixers, amplifiers, speakers, and other audio equipment with dual 1/4-inch jacks.
