Customer reviews - Plantronics CS50-USB

I'm truly very happy with the wireless CS50.  I appreciate receiving the different styles of headphones so I could choose which was most comfortable.  I like the fact that I can move down the hall and even into other rooms and still be answering calls.  I can have a caller on the line with me while I physically leave my desk to research something the caller asked for.  One thing I could not use was the HL10 handset lifter.  I like that it came w/the headset, since in the past I had to order the lifter separately.  The lifter didn't work because it's necessary to lift the bottom of the receiver (the speaker portion) from the base and then be able to replace it, but the lifter could not lift the speaker end high enough for me to get a dial tone.  I reverted to my old handset lifter, which is the flat pad with the long arm, and it works perfectly.  The only other thing I would change is the slim button on the headset that activates the lifter.  Since it's so small, it takes me an extra second to make sure my fingers are on the button before I push it.  I wish it were bigger.  I've never used the mute function because I can't tell if I'm putting it on mute or adjusting the volume on the headset. - Janet
