This headset comes with a ton of extra goodies included. In addition to the headset and A/C charging adapter, you also get 9 different earpieces (3 "scoop" and 6 "mushroom" shapes), two different lengths of USB charging cable, and two ear loops.

Why the boom?

Superior sound quality - it's a no brainer, put the microphone where you speak. Speak softly and still be heard - Nobody likes a loud talker. With the boom, you can maintain discretion when discussing your latest forays on Warcraft or the new Signal that you are on the phone - By extending the boom, you communicate to others that you are engaged in a conversation and are not some crazy person talking to yourself. Not your ordinary boom - Because the Zivio's boom is retractable, you can extend it when you want and store it when you don't.
