Features of the Oasis include the usual answering, ending, and rejecting calls, last number redial, voice-dialing support, call mute, and multipoint, which lets you connect up to two different devices simultaneously. It also has voice alerts that let you know the pairing status of the headset, its battery level, and whether or not you've muted the call. If you've paired the headset with more than one phone, the headset will also tell you whether Phone One or Phone Two is ringing. However, the Oasis does not have A2DP streaming. Though it's only a mono headset, many higher-end headsets have A2DP functionality these days, and it can't quite compete with them if it doesn't have this feature.
We paired the Motorola Oasis with the Apple iPhone 3G. Call quality was pretty good, but not quite at the level we expected. On our end, our callers sounded great--clear, loud, and natural. There was a bit of hiss, but it wasn't distracting. On the other end, however, callers said our voice sounded very harsh; as if it had gone through a digital synthesizer.
As for noise cancellation, we were pleased for the most part. We tested it out in a moving car and at a busy cafe during lunch hour and the headset did a good job of blocking out environmental noise--our callers could still hear what we were saying. Yet, it wasn't perfect. When we tested the headset in front of a desk fan to check out the wind noise reduction, our voice became increasingly fuzzy, and callers couldn't quite make out all of our words.
The Motorola Oasis has a rated talk time of 6 hours and a standby time of 7 days.
