I bet your stylus can’t do what this Bluetooth headset (LBT-PHS02MPSV) can. This is a stylus for smartphones, tablets, and other smart devices. But it also can connect to your device to allow you to receive phone calls. It has a speaker, microphone, answer/hang-up button, and volume control button. It also vibrates when you have a phone call. You can recharge it via a microUSB cable.
This hybrid stylus can go for 4.5 hours on a full charge. It is compatible with Siri. Not sure how much it will cost though.
