These bluetooth hearing aids were very disappointing.  Buy the lower priced Earrck instead.
This  is NOT as good as the lower-priced non-bluetooth Earrck set, and here is why:<br /><br />•1.  On my cell phone, although my voice was crystal clear to the caller, each caller was distorted through the hearing aid.<br /><br />•2.  It had no noise-cancellation.  Callers could hear TV in the background no matter how my head was rotated.<br /><br />•3.  Amplification of distant origin was not good nearly as good as up close.  I had to keep the TV volume much higher, but with the less expensive Earrck I could have the TV at half the volume.<br /><br />•4.  It completely blocked my voice.  I could not hear myself speak.<br /><br />Further, the added controls on the cell phone did not prove valuable, you cannot answer the cell phone by any button on the hearing aid, and there's no button for last number redial.  Further yet, caller ID was not announced, and the cell ringing through the earpieces was louder than the caller's voice.
