Cubilux 6.35mm to 3.5mm Audio Adapter, Gold Plated 1/4" Male to 1/8" Female TRS Stereo AUX Connector Converter for Guitar Keyboard Digital Piano Studio Monitor Amplifier Mixer Splitter, 3-Pack

I'm a professional guitarist (sight-reader of music, playing multiple styles with multiple groups weekly in a large city), and I attached this 4-Channel selector switch to my pedal board that I have a Line 6 Helix on, so that I could plug in multiple instruments and switch seamlessly between them without plugging or unplugging any cables. It's the first thing that my guitar input goes through before my pedals. I ripped off the rubber grip layer on the bottom so that I could attach an adhesive mount for the board, or one could use Velcro similarly.This advertises lossless quality but doesn't use the terminology like "true bypass" or "Hi-Z compatible" like guitarists may be looking for, so I used my best headphones plugged into my Helix to try to discern any noise or sound quality difference when my input is coming from either the switch after my guitar or directly from the guitar, and I could not discern any true difference.I used a very bright sound from a guitar in order to hear the fidelity of the high end. I did not find a perceptible difference in noise or quality of sound, so this is likely a true bypass switch in its construction, and therefore is compatible with Hi-Z input or essentially anything that is built for the audio input like passive guitar pickups. The signal level, the lows, mids, and highs all sounded the same to me when playing the same notes/chords the same way on my instrument, and with the guitar stationary, I could not hear a difference in the static noise level.A good price (about $23 at time of writing), no power required, does what it's supposed to, and legitimately preserves the original signal as far as I can tell. A rare kind of product.

This is great, I use for multiple instruments in my studio ... As I need only 1 at a time and I don't have many inputs in my audio interface, this is a perfect solution. Quiet , solid seems durable and no issues until now.

Inexpensive an effective, needed an audio splitter to send audio to a headphone preamp, and also directly to a different pair of headphones.. oddly i had to insert the TRS cables for headphone preamp only 75 percent in or the audio would come out mono when inserted all the way.. if it works it works

I used Coleman Audio LS3, but it's big/chunky and some what ugly. It's also difficult to fit multiple LS3 on my desk.I looked into alternatives and this one fits the bill great as 1 in 5 out for my home studio. It will kinda work as 5 in 1 out (if you're super careful, so it won't work for me), but after some research, the lack of resistor means you can potentially damage your equipment, so I'd recommend against trying.I really really wish they made dual-TS versions, since this means I had to buy a bunch of TRS to TS Y splitters, but no luck finding one like that. If any of you manage to find one, please let me know! As long as it's cheaper than LS3, I am pretty sure I'll pay (begrudgingly).

I wasn't sure how well this would work given the price, but it is a very soldly built device. The case is metal, not plastic. I needed something to passively switch my headphones between 2 computers including 1 focusrite device, and this does it well.I can hear no reduction in sound quality. It doesn't even make a pop when switching devices like some older units I had did.While it does have a decent weight for the size, my only complaint is it's not quite heavy enough to hold flat when I have larger headphones plugged into it. I have tried several things like command strips to temporarily secure it to my desk or the top of my audio interface, but due to the silicone pad on the bottom, they won't stick.But for what it is at the price it's at I can live with that. I'll sort out a way to stick it in place.

Does the trick. I purchased to send multiple sound to a PA Plus Maestro DMX. It works great.

This is a passive switch which can be used to connect any input to any other input. Any port can be an input or an output, works bi-directionally. Does not need a power supply which is great, too.

I find that there is signal bleed. If I have any "out" channel active, I get some quiet signal through all inactive "out" channels as well. And, for my purposes, that makes this unit unusable. There is also signal loss, but that's going to be a feature of any passive (unpowered) splitter. Otherwise, this is a small, well built little splitter.
