Sony Ericsson is getting a knack for launching duos whenever a music-heavy solution hits the market, rest assured its pared-down edition with a less sophisticated player, worse headset and no memory card in the box is to come. This approach does make some sense, but it gets even better when they position these solutions differently. In the case of the music-savvy Sony Ericsson W380i, it aims primarily at men, whereas the Z555i looks to appeal to the fashion-conscious part of the audience, dressing up the front panel in a pattern somewhat reminiscent of a diamonds facets. It is obviously a hundred percent feminine phone few men will find it attractive, if any. For the most part, the Z555i focuses on 12-22 year old girls who have just come from their orientation ceremony, while older women wont be carried away by its looks. And probably, thats about it the Sony Ericsson Z555i is one of those rare instances when there is not much to say as far as positioning goes.

Design, size, controls

The handsets front fascia is on the quirky side, composed of reflective squares that glare in the sun no matter how you turn and twist it, the Z555i always shines, which is what basically makes your impression of this phone. The design is the Z555is main selling point, the eye-grabber that should distract consumers from its other elements, like pretty cheap plastic on the back and inside.

The handset comes in two flavors - Diamond Black Purple and Dusted Rose. Both are not without a certain aesthetic appeal. Whichever flavor you choose, the casing color will match the front decking (the latter trim even has the volume rocker color-keyed to the casing).

The Z555is front plate houses the lens of a 1.3 Mpix camera along with the loudspeaker The outer display is mounted beneath the casings matte plastic and when inactive prefers to keep very low profile. It is a 128x36 pixel OLED unit with white backlight. Unlike the Sony Ericsson Z555i, its screen employs a horizontal layout, which is somewhat more conventional. The display reads well, even under direct sunlight, although its fancy finish on the front may be troubling while in the sun.

The outer display is filled with a variety of notifications, such as missed calls (if there is only one call on the list, then it will also show the number/contact name) and received messages. However, the display too small to display full phone numbers, but this isnt irritating at all it is still readable.

The handset measures up at 95x49x17 mm and tips our scales at 95 grams. It readily slips into a trousers pocket and certainly wont weigh you down. The Z555i also felt robust in the hand, and we have no grips with its build quality. The Z555i has a tendency to creak in the hands at times, although it is largely due to its battery compartment cover; overall, it doesnt feel rock solid, but as we have just mentioned its build quality was never an issue (although slightly worse than that of the Sony Ericsson W380i).

The left-hand spine sports the Fast Port connector; the M2 memory expansion slot is perched underneath the battery cover; on the right are the volume rocker and the lanyard eyelet.

Opening the Z555i single-handedly is pretty much a breeze, although you will need some time to master it. It turned out that some people didnt find it convenient in this sense, while others simply paid no attention to its folder action.

Since the Z555i is an entry-level solution, it has no QVGA display and enjoys a 176x220 pixel screen (1.9 inches, 262 K colors, TFT), that can accommodate up to 7 text and 4 service lines. The picture quality is quite mediocre, on top of that it is somewhat grainy, yet fares well in the sun all in all, a typical low-tier device.

The number pad is made of glossy plastic; unfortunately, the travel distance here is disappointingly short, but other than that, the Z555is keypad is a breeze to handle. All keys are lit in white, although the backlight is on the dim side, making the buttons visible only in the dark, which may bring about certain hardships.

Back to the table of contents >>>


The back cover firmly sits in its slot, and is easy to open. Removing it reveals a 930 mAh Li-Ion battery (BST-39). As the maker claims, Z555i provides up to 300 hours of standby and up to 7 hours of talk time. In Moscow its battery life averaged two and a half days with moderate use (up to 1 hour of calls, about 30 minutes of games and 20 minutes of browsing). Should you get heavier on its features, you will need to recharge once every 2 days or so. And if you cut your total call time to the very minimum, the battery will stay up and running for about 3-4 days, but thats an improbable scenario. Within the European networks the device will last for at least twice as long in all modes thanks to better coverage. Continuous music playback drains the battery in 13 hours. Its takes the Z555i a tad under 2 hours to charge up.

Upon linking the Z555i with your PC via USB you will be forced to pick connection type specifically whether you will be accessing data stored on the memory card or just keep managing the phone or activate Print mode. For the first mode, we mentioned above the handset turns off, and you gain access to the contents of both the memory card and the phones internal storage. Despite the maker claiming that the Z555i supports USB 2.0, data transfer speed doesnt exceed 500 Kb/s. If you just want your Z555i to turn into a modem, then pick the second option, where you will have a chance to play around with various USB settings for going online.

The handset comes with EDR-enabled Bluetooth 2.0, the menu enables you to turn on enhanced power saving mode. There is also A2DP support, which allows employing wireless headsets with the Z555i. Below is the list of supported profiles:

  • A2DP;
  • Basic Imaging Profile;
  • Basic Printing Profile;
  • Dial-Up Networking Profile;
  • File Transfer Profile;
  • Generic Access Profile;
  • Generic Object Exchange Profile;
  • Handsfree Profile;
  • Headset Profile;
  • HID;
  • JSR-82 Java API;
  • Object Push Profile;
  • Personal Area Network Profile;
  • Serial Port Profile;
  • Service Discovery Application Profile;
  • Synchronization Profile;
  • SyncML OBEX binding.

Memory, Memory cards

The handset ships with about 15 Mb of user-manageable memory. The Z555i can handle memory cards up to 2 Gb; plus, you can always swap cards on the go.

The Z555i puts up typical numbers for the companys current generation of devices, being ahead of most models available on the market. There are no limits on JAR-file size, while HEAP size can range from 512 Kb to 1.5 Mb.

The Z555is camera is no bells and whistles at 1.3 Mpix with no video recording capabilities. Among supported resolutions are 1280x1024 pixels, 640x480 and 320x240; two compression settings, a bunch of overlays (B&W, Negative, Sepia), and white balance. Other than that, we dont have much to add about this handsets camera.

Gesture Control

One of the interesting things about the Z555i is so-called gesture control its disabled by default, but you can always change that from the Settings menu. Basically, when you are receiving a call, or the alarm clock triggers off, a bright white LED sitting next to the camera springs into life, so that when you swing your hand above it, the phone will mute the sound a quite similar ability is available with the Nokia 8800 Arte, where by turning the phone face-down you can reject calls.

But as far as the Z555i goes, this gesture control feature is more a gimmick that is of no real use. Some might really fall for this functionality, but I doubt feats like this will become all the rage any time soon.

Preinstalled applications, themes

Music department

The Z555is Walkman 1.0 player interface coupled with a lackluster pair of earphones you get out of the box make it very clear that this phone is not bent on music, although it is pretty much in line with first Walkman-branded phones and with a couple of custom headphones plugged in holds its own against the Sony Ericsson W380i in terms of sound quality. The music quality is quite average, plus the handsets volume level has obviously been lifted up, as compared to other models in this line-up. I see no point in going over the players standard suite of features you will find more about them in our dedicated review of this platform.

On the plus side, the Z555i also comes equipped with RDS-enabled FM-radio.

The Z555is ring tones volume was never an issue its speaker fared well in most environments. The reception quality was nothing to complain about either. Our only gripe is with the phones vibro alert, which occasionally proves to be on the weak side.

Retailing for 275 USD, the Z555i is not a bargain, although its design partly makes up for the excessive weight of its price tag. It wont become a widely adopted offering and will rather enjoy some sales in a particular niche it is positioned for. The Z555is life on the market wont be eventful or wild; its design will flash for a moment, though. All in all, it is a relatively expensive and not particularly feature-reach offering in its class.
