Bi-directional stereo to stereo balun are interchangeable.Great for long distance audio transmission, which can either transmit or receive maximum of 240ft cable length.No noticeable signal loss, it eliminates the high frequency losses and hum that may occur when your audio cable is too long.

Review: Good quality. Works great. - These are very well made. No complaints. I used them to connect my patio TV to my Sonos amp about 150-feet away via an ethernet cat5 cable. It works great. I did use an optic to analog converter on the TV so that may have boosted the signal but that has nothing to do with the quality of the connectors. I will buy again.
Review: Expectation surpassed. - Splendid
