## Overview

The SPRODIO 2 Way In-line 3.5mm Audio Switch Box M201 offers versatile bidirectional switching between two audio sources or outputs. Featuring an independent ground wire design, it eliminates noise for pristine sound quality. Compatible with both TRRS microphone headsets and TRS headphones, this compact, durable aluminum switcher requires no power supply, making it the perfect plug-and-play solution for professionals and audiophiles seeking seamless audio control.

## Description

The most notable design highlights of this audio switcher are: Independent Ground Wire Design: When you connect two audio sources simultaneously, the ground wires of the two sources are independently separated. When switching channels, the ground wire is also switched, avoiding noise caused by a shared ground and ensuring high-fidelity audio reproduction. (This is different from other products that use a shared ground design.) Compatibility with 3-Segment and 4-Segment Headphone Jacks: This device supports the use of 3-segment (TRS) headphone jacks and is also compatible with 4-segment (TRRS) headphone jacks with microphone functionality. It can be used for audio playback and supports microphone functionality. Compact and Well-Designed: The SPRODIO audio switcher is a compact and meticulously designed 3.5mm bidirectional audio interface switcher, allowing users to conveniently switch between two audio sources/playback devices. Use Cases: Switching Between Devices: Perfect for users who need to switch between two audio sources, such as a computer and a smartphone, without frequently unplugging and re-plugging cables. High-Quality Audio: Ideal for audiophiles or professionals who require clear, low-noise audio transmission. Simplicity: Great for those who want a plug-and-play solution without complicated setups. Compatibility: The device supports both 3-segment (TRS) headphone jacks and 4-segment (TRRS) headphone jacks with microphone functionality, ensuring worry-free usage.

Review: Great for switching between speakers and headphones - I've been using this for 8 months now and it works great for my needs. I have my PC plugged into it, and both desktop speakers & wired earbuds. It sits right under my monitor, and is very easy to switch between A (earbuds) or B (speakers). The fact that it doesn't require power is nice. I also appreciate its small size. It is basically hidden behind my monitor stand. Also its design is great -- it has only the functionality I need. All the ports are on the back so the 3 cables are hidden & out of the way, and the switch is on the front so I can easily reach it. Finally, the noise level seems to be non-existent, as far as I can tell. With the earbuds on and the PC volume turned up to 100, I can't hear any noise at all, with or without any audio playing.
Review: Nice little switch box. Works as advertised. Well made. - Easy to use, works as it should. Small, well made switch box. Can avoid wearing out the jack on my device hopefully with this switch.

## Features

- Audio switch for 3.5mm (1/8") audio jacks. It can be used in two directions: 2 IN 1 OUT & 1 IN 2 OUT
- 2 IN 1 OUT: Connect with two audio sources (example: computer and TV), then connect with one output (example: speaker). The A/B switch pot is for selecting one of the audio sources to be routed to the output.
- 1 IN 2 OUT: Connect with one audio source (example: mp3), then connect with two outputs (example: headphones and speakers). The A/B switch pot is for selecting one of the outputs (2 outputs are not simultaneous).
- Microphone headset also compatible: This box works with any four-segment (TRRS) audio jacks, means that if you plug in headphones with a built-in microphone, the microphone will work through the switch. TRS also Compatible.
- Built in mini size aluminum chassis, looks nice and durable. Passive switch that does not need power supply.

### ⭐⭐⭐⭐⭐ Nice little switch box. Works as advertised. Well made.
*by T***M on June 18, 2026*

Easy to use, works as it should. Small, well made switch box. Can avoid wearing out the jack on my device hopefully with this switch.

### ⭐⭐⭐⭐⭐ Exactly what is advertised
*by K***N on May 7, 2026*

Nice-looking compact audio switch. Does exactly what it says on the tin. Works well so far, but I cannot comment on longevity of the switch yet, as I haven't needed to swap back and forth between my two sources (desktop PC and Steam Deck) very often lately. Did not have the rattle noted in another review. Feels very solid and heavy for its size, due to the casing being metal. Good value for what it does. Keep in mind that this is just a source switcher, volume is controlled by the selected audio source.
