Bidirectional 3.5mm Audio Switch 2 In 1 Out & 1 In 2 Out Stereo Audio Selector with Volume Knob and Free 3.5mm Audio Cable, for PC, Smartphone, Laptop, Headphones and Speakers

This 3.5mm stereo audio switch features a practical bidirectional switching structure to solve the trouble of frequent plugging and unplugging audio devices on your desktop. In 2-in-1 Out mode, you can connect two audio sources such as a computer and a mobile phone, then toggle the switch to listen to audio from either device via one pair of headphones or a single speaker. In 1-in-2 Out mode, it splits one audio signal to two sets of headphones or speakers, enabling two people to share the same music, movie or podcast simultaneously.

Equipped with a precision rotary volume control knob on the body, you can fine-tune the output volume directly on the switcher conveniently, avoiding repeated volume adjustment on connected electronic devices. Adopting high-quality passive audio circuit design, it requires no power supply and produces zero electrical noise, preserving full fidelity of stereo audio for music appreciation and video watching.

A free 3.5mm male-to-male audio cable is included in the package, helping you complete wiring in seconds. The compact solid shell saves desk space and fits easily in a bag for outdoor carry. All ports are standard 3.5mm TRS jacks, widely compatible with iPhones, Android smartphones, notebooks, desktop PCs, MP3 players, wired headsets, desktop sound boxes and car AUX audio systems.

Plug and play with zero setup needed, it is an affordable daily audio management accessory great for home desktop arrangement, office multi-device audio switching, travel shared listening and bedroom private audio distribution.
