Compact yet high quality, Sony Ericsson’s K750i is the first camera phone to merge a 2 Megapixel camera with a small form factor and still achieve results with good colour saturation and comparably crisp detail. The inclusion of auto and macro focus further reinforce a positive impression, even though we’re slightly disappointed by its poor synchronization performance. Connectivity in general is also a tad limited, but the high resolution screen provides a window to an otherwise impressive handset.

The construction of Sony Ericsson K750 is standard. It has quite a conservative design, accentuated by the dark color tone, which is also the most frequent one. The phone we are testing is elaborated in the same dark version. The light version looks a little bit happier. Having in mind the target customer group of the phone, there could hardly be found a more appropriate look than the conservative design of the new K750. Yet, the new model is not the type of phone that everyone gets to like and excitement is not the only feeling it evokes in the customers.

Gone far back in the past are the times when Ericsson mobile phones used to have a metal frame. K750 is made of plastics, just like the rest of all present-day phones. Its silver sides are covered with fine metallic-paint finish; the black-brown plastics are matt in order to make finger prints invisible - a very comfortable characteristic indeed. The only parts of the phone surface that get easily "filthy" are the glass cover of the display and the triad of glossy functional keys. This time Sony Ericsson has not put a cleaning cloth in the phone's box. What alarms even more, however, is the fact that the display is not imbedded - a detail, which could eventually lead to its scratching.

The size of Sony Ericsson K750 is 100 × 46 × 20 mm. The phone weighs 99 g. Its size characteristics send it into the category of small phones. On the background of today's mobile tendencies, however, its 99 g do for a place in the medium-weight category only. Let's now have a look at a small comparative table with a few related mobile phones

The Sony Ericsson K750i's gorgeous display measures nearly 2 inches diagonally, packing in 176x220 pixels and a whopping 262,000 colors, easily beating the K700i's 65,000-color screen. Images looked sharp and drenched with color, boasting plenty of detail. The lively animated menus will seem familiar to owners of the K700i, although we're happy to report that the various menu screens are much less sluggish this time around. We had only a few complaints: it's tough to read the TFT screen in direct sunlight (nothing unusual there), and the sleek display is easy to smudge.

Speaking of the camera, it is one of the best in any cell phone, at 2-megapixels. . Along with the auto-focus system complete with macro mode shooting, users can take pictures with resolutions up to 1,632x1,224 pixels. The 4X digital zoom camera also features a night mode, an 8-second self-timer, black and white, negative, and sepia color effects, white-balance settings; a rapid-fire burst mode, and a panorama mode.

Battery is Li-Pol type, with a capacity of 900 mAh. It is not possible to remove the whole back cover, but a small part of it only. For this reason the battery needs to be tucked into the gap. The SIM card is placed under the battery and is therefore relatively difficult to pull out. What should I add about the duration? For now I can only quote the officially presented statements: up to 400 hours in a stand-by mode or nearly 540 min of phone calls. I do not dare guess the real duration time. The comments on it published by SEMania in its last review were not very positive, so I would say two days of heavy use will be about the maximum.

The K750 is a very capable phone when it comes to multimedia, make no bones about it. Not only does it have the forementioned 2 megapixel camera with auto-focus and a 262k color display, but there is also a very capable music player and an FM radio on board. The FM radio was a pleasant surprise for me, not simply because it was there, but because it worked so well when compared with prior FM equipped phones I have used. In order to use the radio, the included stereo headset needs to be attached since it acts as the antenna. Once that is hooked up, you are free to start channel surfing. The radio produced good audio output, and the RDS equipped tuner application lets you program channels either automatically or manually. The radio can work in the background while you do other things, and can be tied to the dedicated play/pause button on the side of the phone if you so choose.

If you prefer to choose your own musical destiny, however, you might want to link that button to the K750's very capable music player. The player supports real play lists, something many phones lack, and allows you to sort the tracks by artist, title, or the order they were originally added to the play list. Once created, though, you can not rearrange the tracks other than with the sorting methods I just mentioned. The K750's music player has a very nice graphic equalizer function. The equalizer lets you select from several preset settings or do things your own way with a fully manual setting. The standard shuffle and repeat modes are also available, as is the ability to minimize the app so that it runs in the background while you do other things (this slows down the UI a bit, though). Once the music player has started, you can remove the headset and have the music play through the mono speaker on the back of the K750.

The capacity of the internal memory of Sony Ericsson K750 is about 34 MB. The phone manager does not separate the files according to their position or tree structure, but sorts them according to their type. As a result, you will see files from both the internal memory and the memory card placed next to each other. The memory is divided into sections: pictures (placed in a subfolder), video files, and sounds, graphic themes, saved web pages, games and applications. The last folder is reserved for files of all types that do not fit anywhere else.

The Sony Ericsson K750i's wireless connectivity options are top notch, including an infrared port and fully enabled Bluetooth. After dealing with phones and carriers that disable all but the most basic Bluetooth functions, it's a pleasure to see a handset that lets you send and transfer photos, videos, and MP3s, as well as lets you sync contacts and calendar events; the phone was also browsable from our Windows PC and our Mac. Even better, the cell phone comes with a trio of remote-control apps that let you take control of a Bluetooth-enabled system; using the keypad and the joystick, we were able to move our PowerBook's cursor, make left and right clicks, enter carriage returns and tabs, and even click the Escape key and some function buttons. It's a cool feature, one that's guaranteed to raise the hackles of paranoid IT technicians.
