I was originally planning on buying an el cheapo Bluetooth headset for my LG VX8100 but was up-sold to a more expensive, but brand name headset (this Nokia HS-26W).The only pro that I can think of was the earpiece design. The piece that goes behind your ear is flexible and pretty comfortable. Weight wise it's really light weight.No for the cons... It was marketed as having ~5 hours of talk time, and plenty of standby time to boot. This was my biggest complaint - the battery life was closer to an hour.Another problem which plagues many of the low to mid end boom-less headsets is that there's a horrible echo as in the caller hears their own voice.I used this headset for well over a week before returning it. Having to charge it a few times a day just to handle an hour or two of calls was excessive and unnecessary. Add in the echo problem and there wasn't one good reason too keep this HS.
