The next generation iPhone can borrow a convenient feature of Samsung and Huawei.

According to rumors published by Mac Otakara, the next-generation iPhone can transmit audio to two Bluetooth devices simultaneously.

Why would Apple do that? Well, first of all, it's already showing up on some newer Samsung and Huawei phones, so Apple is behind the crowd.

On a more practical side, adding it makes sense because it allows people to stream music in a more flexible way. This would allow two pairs of headphones to be connected to an iPhone, which would be a great way for two people to share music, or connect an iPhone to a car audio system and a set of earbuds.

Rumors don't emphasize which new iPhones will get the new feature, but Apple is expected to roll it out to all new iPhones, not just some iPhones-which could be more expensive.
