SPRODIO 2 Way in-line 3.5mm Audio Switch Box A/B Selector Switcher Compatible with 1/8" Microphone TRRS TRS Independent Ground no noise-M201

I bought this to switch my headset with microphone between two different computers. I like to listen to music on my personal PC but often need to switch to my work laptop for meetings. This switches the headset and the microphone perfectly. No detectable difference in sound quality. A fair price for how simply these things can be built. It would be even better if they offered an option that included a couple of 3ft TRRS cables, I had to buy those separately.

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.

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.

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.

This works great to switch between audio sources going to amplified speakers. Works well and bought several months back still working fine. Sound Quality is good does not introduce any extra noise. Very affordable and happy with purchase.

Dead-simple design makes it feel reliable, even if cheap construction makes it feel chintzy. Mine had a significant rattle and some play when flipping the switch, due to a loosely-constrained PCB, but after padding the switch housing against the end cap with some double-stick foam tape, it feels really sturdy. So far, it works flawlessly for switching between my 3.5mm jack speakers and headset, including my headset's mic for input. No noticable loss in signal quality, no introduced noise. Super satisfied, we'll see if the device lasts.

Nice and small so it takes minimal space on the desktop. Easy to switch between to audio outputs. Metal enclosure.

I needed something to route audio to speakers or Bluetooth headphone transmitter. Works great.
