I bought this headset to replace a corded one that plugged into my cordless phone. I kept having to replace the corded one because the cord would snag on things when I moved around, and the cord would eventually die. The corded ones were costing me about $25 each. This headset was a lot more expensive, but it is so much better in every way. All of the corded headsets I used had volume problems- 2 just weren't loud enough, and the one that was was just barely so. This headset has a volume control on it, and it is loud enough for me when set about medium. The headset is not cumbersome- no cord to catch on things or come unplugged. I use the headband style attachment, and find it very comfortable. There are several earpieces included and I think that most people would find an option to suit them. I have an older house which is quite solidly constructed. It's hard to hear someone calling out from the other end of the house, even though it's just a 1400 sq ft ranch house. I wondered if reception would be a problem if I got too far from the base, but I have had no problems with that, inside or outside the house. No interference when passing by computers, our Tivo, or the microwave, either. I think this headset will last a long time, and for me it was well worth the higher price. I wondered if I was going to want the lifter or keypad accessories, but have found the headset works fine as is. I wouldn't buy it as a replacement for a second phone, though, as it obviously lacks any way to check caller ID or dial out. I dial on a cordless handset,then put on the headset and turn it on. You can actually turn the handset off, then, I think, but then you won't have caller ID or any way to "flash" to a 2nd call if one comes in, so I leave the handset on. I do have to be careful to remember to turn the handset off when I hang up. I wondered if I had to have AT&T phones to use this headset, but this headset works fine with my Panasonic phones.
