Today's boom boxes come in a wide range of styles with a variety of features. Consider what audio sources you want to listen to and where you want to use your boom box to find the right one for you.
Most boom boxes feature CD players. Many offer AM/FM and digital radio access as well. Some still feature cassette player/recorders, which you can use for mix tapes. You'll also find boom boxes that let you connect to portable music devices, such as iPods and MP3 players, often using Bluetooth.
Other features to pay attention to are range, sound quality, battery life and durability. Your needs will depend partly on where you plan to use the boom box. You'll need greater range if you're using the boom box outside than if you're using it at home. Sound quality will matter more if you're using it to listen to music than if you're keeping it in an employee breakroom for emergencies. Battery life is an important consideration if you'll be using the boom box outdoors but matters less if you'll be keeping it indoors on a shelf. Durability will matter more at a construction site than in an office.
At Walmart, you'll find a wide selection of boom boxes and other electronics at Every Day Low Prices.
