The LG HBS-700 provides the usual capability to answer, reject, and end calls. It also has last number redial, call waiting support, and auto reconnect. There's also a Bluetooth ringtone answering function that will play your phone's ringtone for incoming calls through the headset. If you're listening to music when a call comes in, the headset will vibrate on one side. The headset also has multipoint support, meaning you can connect to two devices at once. However, when you're in multipoint mode, you won't be able to use the music streaming function.
Obviously, the HBS-700 also supports Bluetooth streaming music as long as it's from an A2DP-compatible device. It has AVRCP, which lets you play/pause, fast forward, and rewind your music using the headset's controls. You can also change the equalizer or EQ mode from Normal to Bass and vice versa.
We tested the LG HBS-700 with the Apple iPhone 4. Thanks to the headset's easy pairing mode, we didn't need to enter a PIN to pair and connect. The music's audio quality was very good: songs sounded crisp, clean, and clear, and while the Bass mode isn't the best, it did add a little bit of depth to most songs.
We were also pleased with the call quality. Incoming sound was decent--good volume and clear voices on the whole. We did detect quite a bit of hiss and static at times, however. We also thought the voice quality was slightly harsh and digitized.
Callers too reported decent call quality. It wasn't great--there was a heavy background buzz once in a while, and callers said we sounded more machinelike than natural--but in the end, they could still hear us loud and clear for the most part. The headset didn't perform very well in noisier situations, however.
The LG HBS-700 has a rated battery life of 10 hours of talk time and 15 days of standby time.
