Detailed introduction of Sony Ericsson w 550

Appearance design

W550 continues to use the same bright orange-yellow color as W800. The bright colors make W550 look full of dynamic magic, which makes people feel... I can’t resist the urge to possess and buy. The soap-like sleek body adopts the same mysterious rotating design as the S700, which makes the whole machine get rid of the cold and tasteless traditional mobile phone design style. As the second mobile phone in the world with the WALKMAN logo printed on the body, the W550 is believed to be as popular as the W800.

The W550 is very suitable for portability in terms of size. With a measurement of 93×46.5×22.5mm, it is very comfortable to hold in the hand whether it is closed or unscrewed, and has a very good grip. The weight of 102 grams is completely acceptable for an all-round entertainment phone with a rotating design.

The outer casing of the W550 adopts a design that allows you to change the color casing according to your mood. The supplied casing has been treated with a special process. A layer of soft paint is sprayed on the original hard plastic material, which not only It increases the friction when holding it, and at the same time, it prevents the body from getting disgusting fingerprints and oil stains, and at the same time, it raises the W550 to a higher level. Although the W550 with the white color casing looks elegant, it is not as attractive as orange.

The rotating screen operation of the W550 provides 180-degree rotation on the left and right sides. In another sense, it can be understood as a total 360-degree rotation, which is a great improvement compared to the S700. The rotation feeling of the whole machine is quite similar to that of a traditional Japanese flip phone. The clicking sound makes people feel very solid. There is no obstruction in the entire rotation process. The locking position is very firm and the precision of the workmanship makes it feel very solid. People are satisfied.

Due to the influence of the rotating fuselage, the W550 adopts a separate keyboard design. The function keys are located on the surface of the fuselage, while the numeric keys need to be unscrewed before operation. In addition to enhancing the music playback function, the W550 also adds strong support for games, which is mainly reflected in the keyboard. First of all, its eight-way navigation key has been specially designed. The positions of the four main directions are all protruding upward, which is convenient for blind operation. There are also two game-specific button designs at the top of the screen, which provide an excellent solution for playing horizontal games. Great convenience. The circular button with the WALKMAN logo printed on the lower right side of the navigation key provides a quick switching function between the media player and the current operating interface, making it convenient for users to select and switch songs while operating other functions. The key contact area of ??the numeric keyboard is large and the feel is very good. However, when entering text, you need to perform cross-level jump operations. Long-term operations will make your fingers tired.

The screen configuration of the W550 is consistent with that of the K750 and W800. The viewing area of ??the 260,000-color TFT display is 1.8 inches, and the resolution is the same as 176×220 pixels. The display effects of the three are different. The upper and lower parts are in the same position, and the display effect is very satisfactory.

The actual display effect of W550 is very delicate, the color display is bright and full, the color transition is very natural, the layering of the picture is very good, and the display of text is quite sharp. In terms of screen parameter adjustment options, the W550 is the same as the W800 and K750. The menu of the mobile phone only provides adjustment of the screen brightness. Adjustment of the screen contrast can still only be performed in the engineering debugging mode. The rest of the related functions such as support for screen image and other formats are the same as those of the K750 and W800. For detailed functions, you can refer to the past evaluation articles of these two models.

Connect the USB data cable when the power is turned off. The system prompts to find new hardware. Insert the supplied CD. After the new hardware is installed, W550 will connect and communicate with the computer using the management method of removable disks. (Note: This can only be achieved when the power is turned off). After we tested the transmission speed of W550 using USB data cable, its writing speed is basically maintained at around 200K, which is the transmission speed of USB1.1. If you use this speed to transmit 256M data, you still need to wait patiently. After all, This is the fastest data transmission method currently used by W550.

When the computer is turned on, connect the data cable, and the computer will recognize more hardware such as MODEM. After the installation is completed and the management software is installed, data management can be realized while the computer is turned on. The data transmission speed is the same as that of the removable disk. The speed of the state remains consistent.

As the second mobile phone with the WALKMAN logo in the world, the W550, like the W800, supports listening to MP3 songs without turning on the mobile phone function. Every time the phone is turned off, a startup menu will appear, asking the user whether to activate the phone's functions or simply enter the music playback function to enjoy music. The built-in multimedia player can recognize and play MP3 files very well. The W550 is basically consistent with the W800 in terms of playback functions. For detailed functions, you can check out the relevant WALKMAN function test of the W800.

The W550 is equipped with the same in-ear headphones as the W800, and its sound quality performance is basically the same as that of the W800. However, perhaps due to the headphones themselves, the W550 performs very well for low frequencies, but does not perform well for mid and high frequencies. There was obvious distortion in the playback. After changing a pair of headphones for listening, the above performance was well resolved. In terms of multimedia player functions, W550 also adds a sound effect option compared to W800. This is the enhanced stereo playback option, which is equivalent to the 3D sound effect of ordinary MP3 players. After turning on this function, the sound field will suddenly become wider, and The sound effect of the original headphones has been greatly improved.

W550 has two management methods for the transmission and management of MP3 music files. One is to use the supplied Disk2phone software to transmit MP3 files and convert CD music formats, which is more cumbersome to use. Another management method is to use the W550's removable disk management method. Just copy the MP3 music files to the SOUND folder. Our reviewers agree that using the removable disk management method is very convenient, and any data can be seen at a glance. There is no cumbersome and unfamiliar software operation. After all, I believe every friend who uses a computer can use copy and paste.

In addition to the powerful WALKMAN function, W550 also provides good entertainment performance. The two buttons at the top of the screen are the A and B buttons specially provided for JAVA games. There are 3 built-in JAVA The games are all designed for the horizontal version of the W550. The three horizontal versions of "Extreme Snowboard, Gauntlet, and Worm" are very playable.

In terms of battery, W550 uses the same BST-37 battery as W800, with a battery capacity of 900 mAh. In the standby time test, after 1 hour of continuous calls and 20 short messages sent and received After sending and receiving 10 MMS multimedia text messages, the phone can continue to work for about 55 hours, and after 30 minutes of continuous calls, sending and receiving 10 short messages and 5 multimedia text messages, the battery life is about 65 hours. Under the pure music playback test, the W550 can maintain about 27 hours of playback time, which is very close to the nominal 30 hours. When the mobile phone function is turned on, it can maintain about 13 hours of playback time, which is impressive in terms of playback time. People feel very satisfied.

The emergence of W550 once again set off a craze for WALKMAN mobile phones. The built-in 256M memory can meet the needs of ordinary friends, and it also reduces the purchaser’s expenses to a certain extent, but it eliminates the need for a memory stick expansion slot. This feature is really a bit of a shame. The same rotating screen design as the S700 makes it full of wireless vitality. Its powerful music playback capabilities and buttons designed for gaming are all strong selling points of the W550. I believe it can fully attract the younger generation of music consumers. After all, its The price is certainly more acceptable than the W800, and it is a pretty good music and entertainment phone.
