Audio Balun, 2 Pack Stereo RCA to Stereo RCA Audio Extender Over Cat5 / Cat6 UIInosoo 2 RCA to RJ45 Stereo Cable

Hooked it up and works well

I use these when I need to send analog audio over a long distance (over 25 feet) because these allow you 328 feet with no noise or signal loss on regular cat 6.

Works as advertised, build quality is budget but to be expected

This device is not a balun, and introduces buzzing created by groun loop. Don't waste your time, and buy a real balun. A balun is a small transformer which converts an audio or video signal from unbalanced to balanced and vice versa (hence the term "bal*un"). This process eliminates buzzing introduced by a ground loop. This device does NOT do this.

Worked for me for a while, but I decided that such baluns are not necessary or sensible for a speaker-level signal.Also, they do not use the entire CAT5 cable, but only half of the wires. That's probably OK as they are designed for line-level, lower power signals. While this sort of worked for my speakers, it didn't work very well (high resistance from the long, thin wires). My mistake. I absolutely wouldn't recommend baluns for that application.

This product works but when using over CAT6 at over 100 feet there is a hum sound that I don't get when trying another brand balun. The claim of 200' is false and I would recommend this cheap product (unless it's a short run).

I had hoped, based on the description saying ‘balun’ that these might have a tiny transformer to provide ground isolation... but they do not appear so. Metering from tip to sleeve of each rca plug reveals open circuit, ie no transformer inside the black molded rj45 plug. Connecting each ‘balun’ together with a cat5/6 cable reveals that each pin is passed straight thru at DC (very low dc resistance), should be open circuit at dc if there’s a true unbalanced to balanced ‘balun’ taking place. However, if you don’t have any ground loop issues to deal with, these make a quick and easy way to transport stereo rca to rca line level audio.

Significant buzz. Replaced with an alternative product all great. Do not buy if you want no hum.

Used for 200+ft powered speaker wire runs where patch cable and rca style will introduce noise.These are clean clear and easy to use. 4 pairs and they all seem great.

Did not work for me, returned after trying with lots of ground loop noise and zero audio signal.
