Sony Ericsson thinks it has the answer with two new headsets. Sony Ericsson were the first company to use Bluetooth connectivity in mobile headsets and both the HBH-610 and the HBH-PV700 are Bluetooth2.0. Here we look at the HBH-610.

Using Digital Signal Processing, the HBH-610 is capable of some advanced sound balancing, bringing the a promise of excellent clarity to both caller and recipient.

The DSP monitors the volume on the headset and will automatically increase or decrease, should the background noise rise/fall, or the volume of the signal sent by the second party change.

This volume change is almost instant - taking less than a second per adjustment. The echo balancing is great, in car, the reverb and subliminal noise are dulled down, making for a far clearer signal.

In the office, the random shouting still comes through, but any regular background noise is detected and accounted for.

It's worth mentioning the office, as this is billed as a multi-purpose headset, for multiple environments. Ideal for wireless call handling, the device configures with compatible PCs, Voice over IP (VoIP) and PDAs as well as mobiles - including over 20 handsets from the Sony Ericsson range alone.

The colour is black and silver, but the covers are inter-changeable, should you wish to shell out for a colour more befitting you status, while the earpiece on the HBH-610 resembles a traditional in ear headphone, with a metal cover and removable foam cover.

The headset comes boxed with a mains charger and for those fearful of using it, a dangle strap.
