Audio selector 3.5mm Audio Switch Audio Switcher, Passive Speaker Headphone Manual Selector Splitter Box Audio Sharing (2-IN-1-OUT/1-IN-2-OUT)

I have a speaker system that I wanted to use for both my TV and music. In theory, I could just plug them into the TV, but all my speakers are Wi-Fi streaming speakers that spread Spotify around every corner of my house around the house. To avoid having to switch the AUX from my TV to the Chromecast that's sending music to my speakers, I use this. I am happy because -It's ridiculously simple to set up -It's not competing with my other devices for an outlet. -There's a nice tactile feel to the button and a big change in height when it's depressed, so I can know what mode it is in when I try to switch or just by looking at it before I even start to play music/watch TV. -Its aesthetic fits in with my room which has a lot of black furniture, including the TV stand that I stuck it to (may post pictures) Cons -It was $25.99 when I bought it, which is expensive for what it is, but I still bought it so whatever. -Other reviews mention how the volume control knob is exponential and not linear, so there's only a few settings near the max they can use. Not an issue for me because I have 2 other places where I can control the volume (output signal strength of TV/Chromecast & the knob on my AV media receiver), so I just keep it at max on this device at all times. Overall, I like it. If you think this is too expensive or you have audio sources with vastly different signal strengths and no other way to control them besides this knob, I'd look at another option. There were switches cheaper than this that I didn't buy because I was willing to spend an extra few dollars to have this blend in to my media center.

In my COVID home-office setup, I pulled out an old set of computer speakers with a subwoofer and plugged in my laptop to stream music. Then, when I was digging through old drawers, I found an old iPod and unburied an antiquated boom box with an iPod dock. The problem, the boom box speakers are nasty. So I bought a bad splitter cable from Amazon and it was a perpetually frustrating experience. Had to jiggle the plug and never got full volume from my laptop or boom box. Then, the other day, this switcher arrives. It's like seeing color for the first time. Such a genius little cheap device. Assuming nothing's going to corrode or otherwise fail, it's easy and gives top-fidelity from both sound sources. What's also awesome, it works in both directions. I can feed two sound sources into one set of speakers like I'm doing, or I could switch one sound source between two outputs (speakers & headphones, for example). Simple and perfect. Bottom Line: This is what you want to buy. Just make sure you have enough male-to-male skinny boy cables, as this only comes with one (you'll need 3).

I have had this unit for a little over 2 years but the problems started in the first 6 month's which is unfortunate because it had the possibility of being great purchase. I have inspected the board construction and case quality. It appears decent and the case is solid, but the component selection is where the problem starts. As others have mentioned the potentiometer used for volume control is pretty useless, a proper volume control would be logarithmic, but I understand this because those potentiometer's tend to be expensive and you are not paying much for this. The real problem is the A/B switch. It is sub-standard and can fail in short order. Mine is now at the point where every time I switch I must jiggle the A/B to get it to work. If it was just starting to fail now I would not complain, but as I mentioned at the start the problem started 6 months in. This is unacceptable so now I either need to find a new one or find a way to replace this switch.

I have worked in audio / video production in the past. I'm retired now and running a streaming radio station from my bedroom so space on the rack in the corner of the room is at a premium. I needed a switch to move between the station monitor speakers and headphones without always having to plug the headphones in to disable the monitors. I did not know this was in a metal box. That was a pleasant surprise. The volume control was smooth and silky and seems to work well at reducing levels although I won't be needing to use it. Right now, you'd be hard pressed to find the materials and build it yourself for the asking price. About the only improvement that could be made would be to include some small rubber stick on feet for use on a flat surface. This was not a problem for me as I keep a supply of the clear 3M feet on hand.

This is a very well made unit in a nice metal case. It is very small and compact. The PCB is quality as are the components. The variable resistor (aka volume control) is ~5.1k ohm, which was about 10x too much for me. It also has an audio type logarithmic taper (instead of linear) which exacerbates the issue. I am running 2 to 3 Watts out of a HAM radio, and the 5k ohm resistor is just way too much. I need more like a 400 ohm resistor and ideally with a linear taper. In my application, this 5k log taper resistor goes from full volume to dead silent in about 2 clicks, so 80% of the volume control is useless for me. This might be better suited to higher power (>10W or 20W?) applications. I am still using it as a switcher and I have volume knobs on my radios so it is doing the job. I may add a parallel resistor network to the volume control circuit to make it more usable for me, or try and find a direct replacement 400ohm resistor with a linear taper. UPDATE TO MY PREVIOUS REVIEW: The log taper of this thing is very frustrating. Even if your application happens to need exactly a 5k ohm range of resistance, the only action you are going to get from this control happens between 5 and 9. From 0 to 5, and from 9 to 10 - there is going to be very little volume change happening. This device would be much better with a linear taper variable resistor in my opinion. At least then even if your application did not need 5k (or even if it did), the control is going to be much more useful - a broader range of applications is at least going to find some usable and useful range of the control knob with a linear taper. I have attached a graph of the volume control, which was taken from the unit I received using a meter. Even after adding a parallel resistor to each channel and getting the total resistance down to ~400ohm max, the log taper of this control is disappointing - the usable range of the knob is still from 5 to 9.

This has been a dream! I had my computer hooked up to my stereo system. I bought a new computer and wanted them both to be able to use the stereo system. This device is so easy to use. No power plug, no batteries. I just plugged in the audio cable that went to my stereo. Then, with two other audio cables, I plugged each one into the two inputs of the device. Now when I'm on my old computer, I press a button and it has stereo sound. When I'm using my new computer, I press a button, and the stereo sound switches to that PC. It solved a big problem, and literally took me a couple of minutes to set up!!!

When i first set this switch up i was getting really bad static sound when i would switch audio inputs and was ready to return it. Then i decided to try using it again and it no longer made the static sound and works perfectly. I'm assuming the issue was either because one of the audio cables i was using was faulty or one of the cables wasn't fully inserted somewhere.

very handy device, does not introduce any noticable noise or sound degradation under typical usage. The overall look and feel of the product is very nice. my only complaint is the push button switch for selecting channels 1/2. it is scratchy when toggling between the channels. one side may also cut out at times but only during the toggling. Audio to both sides can be restored by 'jiggling' the switch a bit.
