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

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.

very handy, small switch. I use this to switch audio source between my work laptop and gaming PC using the same set of wired headphones. This switch supports both input (mic) and output (audio), which is not very common in my experience. I have not noticed any change in voice or audio quality using this switch. I would recommend this product if you want to use the same headset/headphones w/mic with two PCs without switching cables. Just make sure you have TRRS (4 pole) cables.

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.

There isn't much to say about an A/B switch, I thought, until this one arrived and swiftly demonstrated its perfect functionality and quality brushed metal housing. The switch is not sticky but also not loose, there is no audio bleed-over at all, and the ports all grip 3.5mm plugs with a firmness that suggests to me the device will last for years or decades.

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.

Exactly what I needed, no fuss and cost-effective. I didn't see a lot of these for TRRS (headphone and mic) and for the high prices out there I could have built one, but this one was cheap enough to buy one instead of building it. No problems so far as I'd expect. I use it to switchover combo headphone/mic for work & home computer use.

I wanted a switch to let me use my expensive speakers with my Mac and PC. This worked perfectly with no audio quality issues and no popping or crackling when switching. Very happy and wishing I had bought this years ago.

Broken completely, only one channel gets through. Swapping audio cables does not help, it's definitely the switcher. Physically pressing the switch inwards used to help but now it's broken all the time.
