My wife wants a headset for calls when she is in the house. around 30.00 but when you do a search you don't usually get the specs if it is a iphone4/s compatible . like the skullcandy's don't say iphone 4 and I have learned they better if you want to use a mic. I bought her a Motorola h720 bluetooth earset but I don't think it will work well for voice commands. on the go she has good earbuds but she wants something simple and fast to grab.
