LiNKFOR 4-Port 3.5mm Stereo Audio Switcher - Bi-Directional 4-in-1-out / 1-in-4-out Selector with Volume Knob No Power Required for PC, Phone, Speaker & Headphone

Product Features

• 【Bi-Directional Audio Switch – 4-in-1-out or 1-in-4-out】--- This versatile 3.5mm switcher works both ways: combine four audio sources (like a PC and phone) into one speaker, or send one source (like a laptop) to four outputs (like speakers and headphones) and select one output by switch knob. Avoid constant cable swapping (Note: NOT a Splitter, Only One Input Can Be Played At a Time.)
• 【Maintains Audio Quality Over Distance】--- Designed for clear signal transmission, supporting cable runs up to 8 meters (26 ft) from source to output. Includes a 1m (3.4ft) 3.5mm cable to get you started
• 【Convenient Volume Control & Switch Knob】--- Features a dedicated volume control knob with clear markers for precise adjustment. Switch knob to select input and output source. Anti-slip feet and labelled ports ensure stable, hassle-free operation right out of the box
• 【True Plug & Play – No External Power】--- Requires no batteries or power adapter, drawing minimal power directly from your audio devices. Simply connect your standard 3.5mm cables (one 1m cable included) and it’s ready to use
• 【Broad Compatibility with Important Note】--- Works with most 3.5mm audio devices: smartphones, tablets, computers, speakers, MP3 players, and more. *Please note: Designed for standard 3-segment (TRS) audio jacks, not compatible with 4-segment (TRRS) headset/microphone combos
