Anyone actually use bluetooth with their phone?

[ExcitedJime]

So my son decided to give me his over used iPhone. Took me a week or two to figure out how exactly it all works, but its pretty great. I gave up my old samsung flip phone for it, but the headset i use while on the road does not work. In my search for a new headset my son mentioned bluetooth....so im here asking. Ive seen a few of you out there with these things in your ears...are they worth it? Do they work good? easy to use? I noticed they have speaker phones as well, i have been eyeing this Jabra Cruiser speakerphoneJabra Cruiser speakerphone, just wanted some advice before i bought something i know nearly nothing about!
