    Very good product
    For these money is the best (-50% with 2 pcs). I use them only for speaking. It has a very good speaker and microphone. For music, do not expect much. It's listening moderately though it has a second handset with a cable that connects to bluetooth for stereo music. Long battery life. Very good choice. I propose them to everyone for their purchase
