Which connector is used to carry audio signal for headphones?

• A. 1/4" Phone Plug
• B. RCA Cable
• C. XLR Cable
• D. BNC Cable

Answer: (A)

The main idea is how headphones are fed with audio in typical gear. A 1/4" phone plug is the standard in many professional setups for delivering audio to headphones. It’s a sturdy, widely used connector on mixers, headphone amps, and other studio gear, and it supports the stereo signal that headphones need (left and right with a common ground or a balanced configuration). RCA jacks carry unbalanced line-level stereo signals and are common for consumer audio connections, not the typical direct headphone feed. XLR is a balanced connector used for mics and longer, high-quality line runs, not the usual path to headphones. BNC is for video and timing/comms signals, not audio. So, for carrying audio to headphones, the 1/4" phone plug is the correct choice.
