Inside each set, you will find three different connectors - 2.5mm, 3.5mm, and 4.4mm, as well as a 4-pole connector for creating a wide range of cable types.
Each adapter in the ddHiFi BM4P set, made of durable and conductive aluminum and 24-carat gold-plated copper, is designed for superior signal transmission and can withstand intensive use. The set also includes a small piece of silver-containing wire for soldering and a heat shrink tube, but the cable will need to be purchased separately.
