These earphones are "WONDERFUL" They function and match easily with all my bluetooth devices. The noise is remarkable and the battery life is outstanding. I extremely recommend these. After 5 years of remote job I was drawn (kicking and screaming) back to a desk in the office.: >( The environment is loud and I really do not have anything in common with my cell, i imply office, friends. This headphone collection terminates the crap that is constantly going on and "if" I want to hear any of it I can tune down the volume and hear them really quietly in the background. If I could give them a 10 I would ... okay I am they get a "10" from me !!
