Various implementations include a portable speaker configured to adjust an audio output based on a detected input connection. In a particular case, the portable speaker includes an
enclosure housing at least one electro-acoustic
transducer for providing an audio output, a processor coupled to the
transducer, an audio input module coupled to the processor for receiving an audio input
signal, and a battery configured to power the at least one
transducer, the processor, and the audio input module, an input channel for receiving a wired audio input connection, and at least one
wireless input channel for receiving audio input from a source device via a
wireless connection, where the processor is configured to adjust the
audio signal received from the wired audio input connection if the source device is already connected via the
wireless connection.
