Most Bluetooth headsets work with most Bluetooth devices. For example, a Motorola Bluetooth earpiece will work with an iPhone with no issues, just like it will with pretty much any Android phone. However, there are a few caveats here, and you may be surprised to learn that they have nothing to do with different brands of Bluetooth products but different versions of Bluetooth. Generally speaking, a basic Bluetooth headset is going to work with most recent versions of Bluetooth and even some older ones as they’re usually built to be backward-compatible with older phones that use older versions of Bluetooth. However, phones that are designed to use Bluetooth Smart technology (V4.0 and above) may not be compatible with basic, older versions of Bluetooth. This means that before buying a Bluetooth headset, you should check its version and the version your phone and other gadgets use. While this can be a pain, it’s better than ending up with a Bluetooth headset you cannot connect to wanted devices. Saying that, if you use newer electronics which use newer Bluetooth versions, there’s pretty much nothing to worry about – just purchase a headset that also uses newer Bluetooth versions (V4.0 or above) and you’ll be set.
