LOL Surprise! turquoise-pink wireless headphones are suitable for children aged 3 and up. These wireless kids' headphones feature a built-in microphone and offer two volume levels: 85 dB and a louder setting for situations where you need a volume boost, such as when traveling by plane or train. They can be used with all your favorite devices, including tablets, smartphones, portable gaming devices, and learning tools. The headphones can also be used in wired mode with the included 3.5 mm universal audio sharing cable. Please note that all function buttons and the microphone are disabled when the headphones are used in wired mode; all features are only available when the headphones are used in wireless mode.
