Abstract: Disclosed in the present disclosure are a wireless playback device, a playback control method thereof, and a head-mounted wireless headset system. The device includes: a housing, a headband detection device, a processor, a power amplifier (PA) operational amplification device, and a speaker. The headband detection device collects connection condition data of a headband device and the housing. The processor is connected to the headband detection device and controls the PA operational amplification device to adjust an operation power mode of the speaker according to the connection condition data. The PA operational amplification device is connected to the processor and the speaker, respectively, and adjusts the operation power mode of the speaker according to control of the processor. Therefore, the function automatically switching the headphone function and a small speaker function is realized, and the user experience is improved.
