Summary: Good points Excellent headset really like the quick connect/disconnect feature, 1 headset can easily attach to many different types of device. Bad points Bit pricy but you get what you pay for.
Summary: Couldn't possibly tell you because the cable - without which I cannot use the headset wasn't delivered. No explanation until I rang to query this whereupon It was suggested that I had omitted to order the appropriate cable. 2 weeks later the cable has still not arrived. I had to wait a possible 4 weeks for delivery!!
Summary: Good points Great sound and comfortable for long calls Bad points Foam pads wear out, very difficult to find replacements. Bottom cable required which is not easy to tell which version you need for your specific phone
Summary: Good points Great headset. At last we decided to move away from Plantronics after they failed on us yet again. A blessed move. Very comfortable and excellent sound. What more could we ask for. Bad points none Other thoughts Fast delivery by liGo who were nice enough to offer us a discount when we returned to purchase another 10.
