Background: Many notebooks and tablet PCs feature only a single 3.5mm headset interface. However, many wired headphones use two separate 3.5mm ports—one for audio output and one for microphone input. This adapter solves that compatibility issue by converting a single 3.5mm combo port into two dedicated ports. The item is a 3.5mm 4-pole male to dual 3.5mm female adapter. It converts a 3.5mm headphone/microphone combo port into two distinct ports—one 3.5mm headphone jack and one 3.5mm microphone jack. Compatible with any portable device using a 4-pole 3.5mm TRRS jack, including iPhones, iPods, iPads, notebooks, and tablets. Outer braid made of durable fiber-woven material for enhanced tensile strength.
