SOLMIMI 3.5mm TRRS Headphone Audio Splitter -. Warm Tip 1: This 3.5mm audio splitter does NOT work for dual-TRS-plug headphones, which have separate TRS headphones and microphone plugs. This aux splitter (1 in 2 out) also features three tough shieldings to fully isolate and filter the noise, and maximize sonic purity.
