Many iPhone and iPad users take advantage of a stylus to create better work on their devices. Carrying a decent stylus is not that hard. But the Elecom Stylus Pen and Bluetooth Headset offers you more. It not only lets you interact with your phone but also has a speaker, microphone, answer/hang-up button, and volume control button, so you can answer calls.
This stylus vibrates when you have a new call, so even if your phone is in your pocket, you sill won’t miss phone calls. The device is compatible with Siri. It can be recharged via microUSB. The battery life lasts for 4.5 hours. At this time, we are not sure how much something like this will cost.[via]
