IP67 indicates the speaker is dust-tight and can be submerged in up to 1 meter of water for 30 minutes. Some listings also note that the speaker floats.

Outdoor Boost is a button/mode that increases loudness and clarity for outdoor listening, tuning the audio to sound louder and crisper in open-air environments.

Many listings describe a 'double up' pairing mode that links two speakers — either to boost overall loudness or to enable true wireless stereo with distinct left and right channels. Follow the pairing steps in the model's documentation to set this up.

Listings highlight waterproofing and dustproofing (IP67), floating capability, resistance to dirt, and drop protection; some models are described as drop-tested from about 5 ft.

Listings specify Bluetooth wireless connectivity. One model notes a wireless playback range up to 131 ft (40 m); actual range can vary with environment, obstacles, and the connected device.
