Summary: I bought this to replace a Jabra BT2020 that still worked but was falling apart after 4 years, 5 days a week all day usage (I'm a mobile engineer) and I was fed up of superglueing it. Pro's:- On/off system excelent, positive and easy. Sound quality superb.
Summary: Excellent product. Good sound in either ear but I'm not sure what magic is involved in switching the sound from one side to the other. Battery life great. Pairing is simple. Comfortable even when wearing glasses.
