Hubby is constanly on the move, and due to the nature of his job, his phone is almost always ringing. Most of the time he is driving, too, so I have suggested that he get himself a Bluetooth headset for his phone.
He uses his phone's handfree feature while driving, though, but I have noticed that most of his callers are having a bit of a problem hearing him. I guess it's because of all those background noises inside the car, like the radio/engine, or people chatting.
This weekend we'll be going to the mall, and hopefully, we will find a bluetooth headset there that will fit our budget! :)
