We paired the HS3000 with the Apple iPhone 4, which has A2DP and AVRCP Bluetooth profiles that let you stream music and remotely manage them with play/pause and track shuttle controls. The music keys performed as promised, as did the volume rocker. As we mentioned earlier, the HS3000 comes with three SoundAlive sound modes that you can use to augment your listening experience: Normal, Instrumental, and Vocal. Normal is simply the default, whereas Instrumental attempts to separate out the instrument sound, making it sound louder and sharper than the accompanying vocals. The Vocal effect does the exact opposite, and attempts to elevate the voice above other sounds. In our tests, the latter two effects do work to a certain extent, but we don't think they improved the quality of the music very much. Your mileage may vary, of course.
When wearing the HS3000, you want to position it so that the microphone is facing you; the microphone is located next to the 3.5mm headset jack. Call quality is far more improved this way. We tested the HS3000, and we found call quality to be quite good for the most part. We didn't experience any static or crackling and we thought our callers sounded loud and clear. Callers did say our voice was perhaps a touch muddy, but it wasn't too different compared with when we weren't using the headset. They also detected a very distant hum, but it wasn't distracting. Callers reported great call quality on the whole, without much background noise.
The HS3000 has all the usual Bluetooth headset features like last number redial, voice dialing where available, call mute, and the capability to answer, reject, and end calls. It also provides voice prompts during certain actions like powering on/of, or when it's in pairing mode, just to keep you informed of the headset's current status. You can also turn off voice prompts if you like. The HS3000 also has a battery indicator. Last but not least, the HS3000 has multipoint connectivity so you can connect it with up to two different devices at the same time.
The Samsung HS3000 has a rated battery life of 7 hours talk time, 6 hours music playback, and seven days standby time.
