NextLink Bluespoon Bluetooth headset
This is one of the first headsets that was actually able to achieve 30 feet operation range in open spaces. Nevertheless, when I use it in my apartment, the range of operation is restricted to about 15 feet when moving, and around 25 feet when the user is standing still, which is the best range we have seen in a Bluetooth headset so far. I did not notice any sound distortion when moving around the room within 15 feet. On the other hand, if you loose eyesight between the unit and the phone (wall, refrigerator or other solid object blocking the view)and you continuously move around sound distortion appears.
This was also the first headset that I was able to use through a wall. As you can see from my sound/range tests, I left the phone in one room, and went to the adjacent one which was separated by a drywall. The total distance between the BlueSpoon and the T68i was around 15 feet. The sound produced was clear with not distortion or static.
BlueSpoon's battery life is very impressive. It is the longest we have seen in a similar device. With a fully charged unit I talked for 4 hours and 20 minutes, before the battery died. Stand-by time was around 220 hours with no airtime. If you talk for 40 minutes a day, you can get around 2 days of stand by, which is very decent. It takes around 1.5 hours to fully charge the unit.
