Advantages and disadvantages of Sony Ericsson K750C

In the past, a series of mobile phones of Sony Ericsson did not support full-screen standby display of standby wallpaper, but the emergence of K750 made all this history. K750 only needs to set the picture with appropriate screen resolution or proportion as wallpaper, and it can be displayed in full screen in standby mode. Although there are still transparent borders and shortcut key prompt boxes related to information status at the top and bottom of the screen, it has little effect on the screen. After switching different themes, the border will be displayed in different states, but it will remain transparent all the time.

In order to make it easier for users to open the functions with high daily usage, K750 adds a shortcut menu mode above the navigation key. In standby mode, just press this shortcut key to enter the commonly used shortcut menu mode, which provides a way to quickly create new notes. The left and right pull-down menus also have shortcut operation options such as Bluetooth, demo guide, calendar, lighting, infrared, silent mode, etc., and also provide the function of online bookmark. In addition, in the aspect of file manager, K750 adds the folder option of web pages, which is not only the storage location of web page bookmarks and favorites, but also provides the function of saving web pages. In the state of browsing related pages, you can choose to save the page to your mobile phone for offline browsing in the future.

With the support of the retail version, we got the support of the original headphones. After playing MP3 audition, the sound quality of headphones is better than those equipped with K700 and S700. The sound quality is full and round, and the bass is strong but not scattered. The frequency response of medium, high and low bass is handled very well. After turning on the sound effect of MEGE BASS, the bass performance of headphones is particularly prominent. As a mobile phone supporting MP3 playback, the headphones equipped with K750 are far from the top of many machines.

In addition to supporting MP3 music, K750' s built-in video player also supports MPEG4-4 and 3G-P video playback. In view of the shortcomings of K700 in video playback, K750 adds the function of full-screen video playback, and abandons the previous option of watching video only in a small window, which makes video appreciation more visually impactful and creates a good entertainment environment for users again.

In terms of radio function, K750 has also made great optimization and improvement for K700. In addition to simple automatic channel search, in order to avoid the deviation of automatic channel search, users can also fine-tune the searched frequency with an adjustment accuracy of 0. 1Hz to ensure the reception quality of the radio. In addition to fine-tuning the frequency, the K750 also provides an auto-focus switching function. When the reception quality of a radio station is poor, it will automatically switch to the standby frequency of the station to improve the listening quality. However, this function needs the support of the radio station to be used normally. Although it is not suitable for every radio station, it is a thoughtful function. The radio not only supports manual frequency setting, but also provides storage space for a total of 20 stations. So that users can quickly switch stations.

Connection extension

K750 adopts several newly designed fast port communication interfaces, so it needs to replace the data cable and accessories. K750 also needs to install the corresponding driver, which is synchronized through the data line and transmitted through the Bluetooth connection. After the driver is connected to the data cable, the system will automatically install the relevant hardware and drivers, and finally the memory stick Pro Duo will be regarded as a mobile disk. However, the compatibility of the installation CD of K750 needs to be improved, because it is impossible to install any programs on the CD under Windows 2003.

After the data cable is connected, the synchronization program will ask whether it is necessary to synchronize the time of the computer, which saves the trouble of frequently adjusting the time. Users can set related names for mobile phones, and through the connection, users can manage the 32M capacity inside the mobile phone, but it is puzzling that the capacity cannot be viewed through its software. In order to test the file transfer speed of K750, we transfer the same file to the memory and memory card of the mobile phone respectively, and measure the required time with a stopwatch. It is found that the same 2.43MB file package takes 2 minutes and 38 seconds to transfer to the main memory of the mobile phone, and the speed is less than 16Kbps, while it only takes 8 seconds to transfer to the memory stick, and the speed is about 290Kbps.

K750 CD has a built-in image editor. After opening the graphic editor, users can open any picture for editing. The editing interface has a red box, which frames the picture with the resolution displayed on the K750 screen. Just drag the box to select the corresponding required display content, and then click download to automatically transmit it to the mobile phone through the data cable. In addition to the simple clipping function, users can also adjust the color, contrast and brightness of the picture, allowing users to set it freely and simply.

K750 CD also provides the editing function of multimedia MMS. You can not only choose the background of MMS, add music, pictures and words at will, but also edit the recording in real time, making the editing of MMS more convenient and faster, which is several times more efficient than editing MMS on mobile phones.

Remote control function

In order to make full use of the wireless function of Bluetooth, K750 provides the function of remotely controlling the computer operation through Bluetooth. Generally speaking, K750 provides support for three options, namely, slide presenter, MediaPlayer and desktop control function. Remote control can only be carried out after the CD driver is installed.

The remote control function of the slide presenter of K750 not only supports the windows in the running state of PowerPoint program, but also supports the independent running of the files packaged by PPT. In addition to supporting mouse movement, 1 and 3 keys provide outline switching, volume control keys provide slide switching, and 2 and 5 keys are keys to start and stop playing. For the support of Bluetooth remote control slide show, users can have a wider range of activities when giving speeches and demonstrations, which saves the trouble of wired remote control or infrared directional remote control and brings great convenience to business people.

The remote control function of MediaPlayer can only be performed accurately and effectively when MediaPlayer is turned on. After starting MediaPlayer, you only need to touch the K750 side in your hand, so as to save troublesome mouse operation and quickly perform fast forward, fast backward, fast forward, music selection, play, pause, volume adjustment and other operations. In the process of operation, the corresponding shortcut button function is displayed on the screen to provide the user with the indication function. MediaPlayer's remote control support makes it easy to play movies and MP3, avoiding being in front of the computer all the time, making K750 a Bluetooth remote control at once.

Desktop options directly turn K750 into a Bluetooth wireless mouse, which can not only control the mouse up and down, left and right through the rocker, but also turn on and off the touch options, switch windows, advance and retreat the browser, and operate the mouse even if it is far away from the computer.

From the supplementary test of K750, we can further see that Sony Ericsson has improved and excelled the K750, which has an excellent side for both entertainment and business applications. Its outstanding performance in all aspects is satisfactory, and the low-priced K750 has attracted the attention of many consumers, believing that it can recreate the sales myth of T6 18.
