The so-called listening nodes, or supernodes, are the full nodes that are made publicly visible and accessible. As such, they can communicate with any other node that establishes a connection with them. So any fully validating node that is not hidden can be considered a listening node. This type of node is responsible for providing blockchain data to other nodes, but they may also function as a communication bridge.
Lastly, the lightweight or SPV clients are the ones that use the Bitcoin blockchain but don’t function as validating nodes. They simply gather information from supernodes, acting as a communication endpoint. As such, these nodes don’t keep a copy of the blockchain and don’t contribute to the security of the network.
