The ProMaster 7990 is a coiled audio cable that lets you connect a microphone or wireless receiver with a common 3.5mm TRS output connector to the 3.5mm TRRS headphone jack of a smartphone, tablet, computer or similar device.
This cable is compatible with iOS, Android, Mac OS, Windows, and a variety of other operating systems (some smart devices lacking a native 3.5mm TRRS port may require an adapter).
Each end of this cable is terminated with a right angle connector. A small label is also applied near each end of the cable to identify its most common useage. One end is labeled "Microphone" and the other is labeled "Smart Device". The tips are gold-plated for protection against corrosion.
This cable is 8 1/2" long in a relaxed position. The coiled design allows you to stretch it up to 20" comfortably and without too much stress.
