Review on 🔌 Hosa YMM-261 Stereo Breakout Cable - 3.5 mm TRS to Dual 3.5 mm TSF by Andre Tenk

This cable splits the stereo channels. It's different (but similar) to a DJ splitter cable. This cable takes each channel of a stereo pair and outputs it to the appropriate channel on each output. This is really important to understand: if you plug a pair of stereo headphones into the left output, you will only hear the sound in the left headphone. Likewise, when connected to the right output, you will hear the sound in the left earphone. On the other hand, a DJ splitter takes each channel in a stereo pair and converts it into two mono signals that appear on both channels of each stereo output. So taking the headphone example again, for the left channel you will hear the audio through both headphones at the same time, but they are synced mono channels.
