Beats headphones are designed for convenience, and while you can connect them to a charger, it is generally not recommended to use them while they are charging. This is primarily because using headphones during charging may lead to potential issues, such as overheating or reduced performance of the battery over time. Moreover, many models may automatically pause music playback or disable certain features while charging. For the best user experience and to maintain the longevity of the headphones, it is advisable to charge them when they are not in use. If you would like more specific information about your particular model, or any guidelines provided by Beats, one could check the official Beats website for detailed product information as well as user manuals.
