Many models include additional inputs and playback options such as USB and microSD card slots, a 3.5 mm aux input, and line-in microphone inputs. Some boombox-style units also offer cassette playback/recording and built-in AM/FM/SW radio.

Speakers range from compact to boombox-style. Heights run roughly from about 4.09 inches up to about 8.86 inches, and weights span from around 0.5 pounds for small models up to about 4.86 pounds for larger boombox-style units.

Protection ratings vary by model. Several list IP67 (waterproof and dustproof, submersible to 1 m for 30 minutes; some models are noted to float). Some larger boombox-style units are described as water-resistant/sandproof with an IP66 rating.

Pairing options differ by model: some use app-based grouping to link many speakers, others support pairing two speakers to double output or enable true stereo, and certain boombox-style units offer a stereo-link feature for pairing like speakers.

Durability features include IP67 waterproofing and dust protection (some models noted as floatable and submersible to 1 m for 30 minutes), IP66 water-resistance and sandproofing on some boombox listings, drop-tested construction (e.g., tested from 5 ft), rugged performance fabric, and general dirt- and drop-resistant claims.
