Wireless means no messy wires to get caught up in, and no broken cables. As they are made of foam they bend twist and withstand the punishment kids will give them.
Simply charge the internal battery using a standard USB socket using the lead supplied (you can use a socket on a computer or a standard phone charger) and you are ready to pair.
Use the normal Bluetooth pairing function on your device to locate the Headfoams and then press pair. After the first pairing, the Headfoams will automatically pair with this device again in the future.
The sound is limited to 85BdB which is a safe listening level as promoted in European Directives. This will safeguard against long term hearing damage caused by excessive headphone levels.
