I just bought this to replace the BT800 I have. I was after something that fits more securely and is not as heavy (the 800 is like trying to hang a brick from your ear with a rubber band). The 250V is definitely more comfortable, but that's all. It is far inferior in all other aspects. The range is claimed to be 30 feet. I get maybe 1 foot before static is unbearable. I might as well use the headset if I have to hold it next to my ear anyway!Also, this may be a quirk of the phone that I use (motorola v330), but when this headset is turned on, it immediately triggers the voice name function which I have to kill. I could live with that if the range was better...Tomorrow I am returning it. I am going to try the motorola models next.
