I wear the ML 20 run daily about 6-7 hours in a car. Even there are noises of a rarity. I myself am also the phone more pleasant than with the iPhone 5s what I use with the headset.
Battery performance is really very, very good at the small part. I can manage a full week, yet he says: "Battery medium". And though it runs continuously with Bluetooth. And with mobile, we know how fast the battery is empty.
What I can say is that Plantronics is a very good brand, and at the price it is an absolute buy recommendation.
Oh yes. I highly recommend this multipoint function also recommend and it's easy to activate them. Just when turning the call key and hold. The announcement follows. Pairing we hear "Phone1 connected" or "Connected Phone2".
So if a device seeks what he has to use constantly is operated absolutely well with the ML 20.
Hope the review helps you with your purchase decision.
