Most play standard audio CDs and are compatible with CD-R and CD-RW discs. A few listings also note DVD playback support, but that is uncommon.
Many include AM/FM tuners with either built-in or telescoping antennas. Some models feature digital or PLL tuning for more stable reception.
Most offer a 3.5 mm AUX input for wired playback from phones or MP3 players. A few modernized retro models also list Bluetooth streaming and USB playback options.
Some retro boomboxes combine a top-loading CD player with a cassette deck and include cassette recording or one-touch recording functions, often alongside an AM/FM radio.
Power options vary by model: some rely on AC power only, others accept removable batteries (examples cited include 2 AA or 6 C cells), and a few list rechargeable batteries or two-way operation (AC plus battery).
Many are compact and lightweight and include carrying handles for transport. Several offer two-way power (AC/DC plus battery) for portable use and commonly include a 3.5 mm AUX input to connect phones or MP3 players.
