Not only with Nokia phones but you can use the headset with compatible devices that support Bluetooth wireless technology.

Bluetooth Wireless Technology

Bluetooth wireless technology allows you to connect compatible devices without cables. A bluetooth connection does not require that the headset and the other device be in line of sight, but the maximum distance between the devices is 10 meters (33 feet). The closer the devices are to each other, the better is the performance. In some point, connection is subject to interference from distance and obstructions or other electronic devices.

Repair the Damaged Headset

We've been using the headset for quite some time. The headset has an internal, non-removable, rechargeable battery. It is placed left side near the speaker. The design is light and compact. Somehow, it happened that my younger cousin over-pushed the charger connector that destroyed the charging pin inside. In order to troubleshoot, headset should be dismantle. We have to align it carefully, else, it has to be replace. Luckily, with some sort of collected information. We learnt that it is too simple to disassemble.
