A phone cord is a flexible cable designed to connect telephones or handsets to their base units, wall jacks, or other communication devices. Typically made with durable plastic insulation and coiled or straight in design, it ensures clear transmission of voice signals without interference. Coiled cords are stretchable and convenient, allowing freedom of movement while keeping desks tidy, while straight cords provide longer reach in fixed setups. Standard phone cords usually come with RJ11 connectors for easy plug-and-play compatibility with most landline telephones. Lightweight yet sturdy, a phone cord is an essential accessory for reliable voice communication in homes, offices, and businesses.
