Bluetooth headsets are wireless devices that allow users to listen to audio and make phone calls without the need for cables. They connect to smartphones, tablets, and other compatible devices using Bluetooth technology, which enables short-range communication. These headsets come in various styles, including over-ear, on-ear, and in-ear designs, catering to different preferences and comfort levels. Most Bluetooth headsets feature built-in microphones for hands-free calling and often include controls for adjusting volume, skipping tracks, and answering calls. They are popular for their convenience, allowing users to multitask while enjoying music or taking calls, making them ideal for both personal and professional use.
