NEXTLINK INVISIO B3 Review
We expected the sound quality to be one of the B3’s strong sides. Unfortunately, we were wrong. The sound through the headset is not loud enough; the voices are clear, but sometimes sharp and hard to make out. It’s the same on the other end of the line. Surprisingly, even though the B3 can be used in somewhat windy or noisy environment, the surrounding noises sound like a background and the only thing that prevented us from having a normal conversation was the low level of the sound.
We are disappointed with the battery life of the headset. During our tests, it only lasted for 3 hours and 30 minutes of talk time, and according to the official data, provided by the manufacturer, you are supposed to easily get at least 6 hours. These results are very strange and having in mind the size of the device, we don’t see why a stronger battery has not been used.
To a certain extent, the INVSIO B3 disappointed us. On one hand, it is very comfortable for continuous use, it has a nice design and is pretty light. On the other, the unhandy buttons and the low sound level during a conversation make it unsuitable for heavy usage.
In the end, it really depends on how you are going to use the device. If you need to make a lot of calls, including conference ones, you are better off choosing a more complicated model with user-friendly buttons. If you only make short calls, sometimes even in a noisy environment, and you also care about comfort, the INVISO B3 is a decent choice.
