Looks like a regular watch, caller ID information, vibration alert

Can't read SMS messages, price, limited functionality

The MBW-200 Bluetooth watch is a bit of a gadget than a mobile phone replacement, since you can't read any incoming text messages, but the caller ID and vibrating functions are nice inclusions.

Simple design, good sound considering its size, easy to use, OLED display

OLED screen will only show track names if you connect a Sony Ericsson phone, distorts at full volume, volume buttons annoyingly positioned

Sony Ericsson's MBS-200 Wireless Portable Speaker produces surprisingly punchy sound given how small it is. It's also versatile: it can be connected via Bluetooth or a standard line-in cable.

Dual speakers, text-to-speech, OLED display, good sound quality

Steep price, a little large, phone book feature requires a Sony Ericsson phone

Sony Ericsson's HCB-150 offers above average sound quality and features an OLED display, but it's a little pricey.

Price, compact and lightweight, FM radio, headset, flashlight, good call quality

Spongy controls, poor viewing angle of display, ring tones could be louder

The Vodafone-exclusive Nokia 1650 fills the void if you're after a cheap as chips phone for basic calls and text. The spongy controls are a drawback, but the included FM radio and flashlight may come in handy.

Simple to use, excellent concept, good sound quality, Tracker application an ideal fitness companion

Only works with certain Sony Ericsson phones, Wayfinder requires a fee for full use, user experience isn't the best on a small display

If you want a fully fledged GPS navigator, you are best off purchasing either a portable in-car unit or a handheld device with a larger screen. If you want to track your fitness data, then the HGE-100 may be worth a look.

Powered by the car lighter, universal for any MP3 player, slim

Can't take batteries, won't charge your MP3 player, not automatic

Although it's a simple device, it's quite a handy one to have if you're on the road a lot and need to have your music on hand.

Built-in FM transmitter allows music and call streaming through car stereo, StationFinder, incoming caller ID announcements

Outgoing voice sometimes lacks quality

The MOTOROKR T505 certainly adds a twist to the normally standard line of handsfree speakerphones. The built-in FM transmitter and StationFinder feature makes it an outstanding choice, even if outgoing audio could be slightly improved.

Vibration alert, caller ID information on-screen, music controls

Limited functionality, price

The MBW-150 makes minimal improvements over its predecessor in terms of functionality, so it remains an expensive device considering the features offered.

Good audio quality considering price, Can be used with both handsets or MP3 players

Flimsy design, Cable too short when in 3.5mm mode

While not as convenient as its wireless brothers, Sony Ericsson's HPM-85 offers better quality audio and a comfortable design, making it a good choice if you can handle a wired unit.
