I have had a lot of smart phones but never used bluetooth headsets and have a few questions. Can you get a bluetooth earpiece for answering phone calls that lets you answer from the headset once paired? Do all the earpieces support streaming or playing music/sprint tv audio/Google listen? Are they all mono or do some single earpieces have stereo? Is there an industry standard for noise reduction that I should look for in the feature list? Any other tips if I just want to buy one and be satisfied its the right one? The one i've eye'd is the Jabra BT530. Thanks in advance!
