Plantronics Explorer 320

On the front of the Plantronics Explorer 320 box are three words in bold black writing -'Easy to Use". Here's the good news - the Explorer 320 is by far the simplest Bluetooth headset we've ever tested. The bad news is that it isn't that comfortable to wear, largely due to the rubberised earbud.

The 320 is designed in an over-the-ear style and can be worn on either ear. The unit is definitely lightweight and compact, but we much prefer the ear-gels on the Plantronics 640.

The Explorer 320 has really only one control on the front. When pressed, it acts as a button to access certain features and when toggled from side to side, it adjusts the volume. Additionally, Plantronics have programmed the unit to emit sound tones with each different control press, so you'll know exactly what function you're accessing when wearing it. If you have the headset off, a small blue light on the side of the unit also acts an operational indicator.

There are only few options available on this device - answering/ending a call, rejecting a call, dialing the last number or activating voice dialing. These are all performed by holding down the small button for a certain duration. We had no problems at all in pairing the device or using it, and a quick once-over of the manual was all we needed to be comfortable with all the functions.

The feature we liked best on the Explorer 320 is a small one, but worth noting. If you perform a long key press, the headset automatically switches the call back to your mobile. A short key press will divert the call back to the headset.

We would recommend this device for anyone who hasn't used a Bluetooth headset before, or doesn't need a broad array of features. The package simply contains the Explorer 320 and an AC adapter - there are no wires, cables, CDs or accessories to speak of. The unit has an adequate 8 hours of talk time.
