Decided to get a Bluetooth headset after the corded retractable headset my wife had was destroyed by my toddler. I was purchasing the headset for a Sprint Sanyo Katana I, and I didn't feel like shelling out the extra dough to buy one from the Sprint store. So I did some research, and found that the reviews for the Jabra BT160 were good enough, it was compatible with the Katana - plus it had the changeable faceplates which was pretty innovative.It came in a plastic blister package, with a very short manual. After reading that through and reading the Katana's manual, I turned it on and connected the Bluetooth signals. At first, I thought I'd bought a dud, but it turned out that I'd incorrectly set the Katana bluetooth settings to speakerphone instead of phone - very poor terminology on Sanyo's part. After that was fixed, it worked fine. The only trouble is, for whatever reason, if I have the headset on and connected, then dial a number using the handset, it won't transfer the call to the headset unless you hang up, then press the main button on the headset twice. Otherwise, it is quite light and comfortable to wear, it picks up my voice quite well, and the speaker volume is audible even in noisy supermarkets. The speaker does not go into your ear (like many corded headsets) it rests on top. It seems to hold a charge at least for a full day, even with several hours of talk time, I usually plug it in at night so I haven't lost a call on it yet. I've even (accidentally) walked away from the phone and was still able to talk on it about 25 feet away. The faceplates are simple to change, but you have to find someplace to store all the extras when you're not using them.So I would highly recommend this headset except for the call transfer, which I have a feeling is probably due to a setting problem with my phone, not the headset.
