Wolfson chip BBK i399 mobile phone review · Source: Tianji.com Mobile Channel 2008-7-25 16:32:34 · BBK is the earliest company to focus on the research and development of music mobile phones. Its products have always been representatives of music mobile phones. Nowadays, no matter in terms of workmanship, The performance is still quite mature, especially after using the Wolfson audio processing chip, the sound quality has attracted more attention. Recently, this site received a review prototype of BBK's new i399 from the manufacturer. How attractive is the Wolfson chip? ? Below I will give you a detailed review of this Wolfson chip BBK i399! The appearance of BBK i399 adopts the straight-plate shape that is more common in mobile phones. The front material of the fuselage is made of metal aluminum alloy, which looks full of texture, and its panel is made in a brushed style, which looks very exquisite. The BBK i399 has a very thin and light body and can be easily inserted into a trouser pocket without looking bulky in summer. The BBK i399 mobile phone is equipped with a 2.4-inch screen, 260,000-color TFT material, and the resolution has reached the size of QVGA (240×320 pixels), the mainstream mobile phone nowadays. The top of the screen is the BBK i399 bar-shaped earpiece, and the bottom is the BBK English LOGO. . Since there is no obvious gap between the screen and the metal body, the good thing is that it is not easy to accumulate dust and oil. The bad thing is that the screen is easy to wear and tear. It is recommended that users add a screen sticker to protect the screen cleanliness when using it. The keyboard function keypad of BBK i399 adopts the design of five-way disc, left and right soft keys and answer and hang-up keys. Five of the discs adopt a silver thread design, which looks more eye-catching on the black body, while the numeric keyboard BBK has placed the three keys "*", "0" and "#" on the right side of the keyboard, which will take some getting used to for friends who are using this phone for the first time. The keys have moderate travel and are comfortable to press. The surroundings of the fuselage are very simple, using piano paint, which feels smooth to the touch. The red metal rim adds a touch of vitality and charm to the black fuselage, making the phone as a whole not too monotonous. There are no buttons on the side and only one on the bottom. USB jack, this kind of setting is still rare on current mobile phones where space is expensive. It seems very simple and bright, but it may cause some inconvenience in operation, with pros and cons. The design on the back is equally simple, with only a 2-megapixel lens and speaker. Although it is made of plastic, it has been frosted and feels quite delicate. Since the lens protrudes from the body, it is prone to wear and tear, so be careful when using it. Appearance summary: The editor's first impression of BBK i399 is that it is relatively thin and light, with relatively sophisticated materials and workmanship. It feels very comfortable in the hand. The button settings are traditional and simple, especially there is no button on the edge of the fuselage. While it increases the feel, it also makes the operation a little more cumbersome. It’s half the merit and the other half, but overall it’s pretty good. The screen of BBK i399 is a 260,000-color QVGA (240 × 320 pixels) screen. The display effect is quite good, the colors are saturated, and the sharpness of the text is also good. However, the resolution is average and the fonts have slight burrs and are not delicate enough. BBK i399 still uses the nine-square menu mode. The menu icons are refreshing and three-dimensional. The phone book of BBK i399 mobile phone adopts a business card-style design. In one phone book, you can store names, phone numbers, email addresses, fax numbers, and companies. The name and other information is quite comprehensive. And supporting customized ringtones and pictures can give us more DIY space. i399 provides us with storage space for 1000 phone entries, which should be enough for the average user. At the same time, the phone book group function provided in the mobile phone allows us to better manage the i399 phone book. On the dialing menu, i399 is relatively simple, with a white background and large black font numbers, which can be seen clearly. In terms of text message input, BBK i399 supports intelligent pinyin and stroke input with good speed. The phone itself can accommodate 300 text messages.

In addition to text messages, BBK i399 also supports email and PUSH inboxes, which is undoubtedly very practical for business people and is in line with the development trend of mobile phones as portable network terminals. The overall framing is relatively smooth, with a slight smear. The maximum photo size can be 1600*1200. From the imaging effect, the color reproduction of the photos is better, but the clarity and sharpness are slightly lacking. This is also related to the fact that the lens does not have autofocus, but overall sufficient to meet the needs of general users. In terms of options, including exposure compensation, continuous shooting, white balance, night mode, etc., it is relatively rich. In terms of photography, it can shoot 352*288 MP4 format video files, and has options such as white balance, night mode, and special effects that can be adjusted. The playability is pretty good. In terms of video, this phone also has a built-in independent video player that can play video formats such as MP4, 3GP and AVI. The smoothness is satisfactory, but this phone does not support QVGA size video playback, but supports full-screen playback. I believe audio playback is what everyone pays most attention to, and it is also the biggest highlight of the BBK i399 phone. Since it uses a Wolfson audio processing chip, we are looking forward to the audio performance of this phone. Friends who are familiar with the MP3 market will be familiar with Wolfson. Due to cost and other factors, well-known brands such as Meizu are currently replacing Philips chips with Wolfson chips, including a considerable number of Sony PSP, Microsoft Xbox, etc. of heavyweight products have chosen Wolfson, which shows that Wolfson’s advantages lie not only in cost but also in performance. In standby mode, press the circular button in the middle of the circular navigation button to enter the shortcut mode of the music player. We used Tsai Chin's "Ferry" as a trial song to test the audio effect of BBK i399. The playback interface has a simple and elegant style. From the playback effect, the vocal performance is quite good, the treble is clear and transparent, the midrange is tactful and true, and it is comfortable to the ears. The bass dive is slightly lacking, but overall it's still acceptable and the overall performance is commendable. In the tool column, we see that there are items such as learning world, commonly used tools and games. The learning world mainly contains English words and vocabulary for various examinations. With the built-in repeater function, I believe it is very suitable for students and friends to use. You can find calendar, alarm clock, memo, etc. in the tool to facilitate users’ daily needs. The phone has two built-in games: Stacking Blocks and Super Circle, which are very playable. The value-added service provides the after-sales service contact information of BBK mobile phones across the country to facilitate user inquiries, which is very considerate. Battery life The BBK i399 is equipped with an 800 mAh lithium battery. This capacity is relatively average for a music phone. Fortunately, the BBK i399 has good battery life, and a battery of the same capacity is also included as a backup. During the evaluation period, it took 30 minutes of phone calls, 10 text messages, 2 hours of music, and 5 photos every day. After using it for about 2 and a half days, it showed that the battery was insufficient. It is still necessary to carry a spare battery. Evaluation summary: Nowadays, there seems to be a "music boom" in mobile phones. Many manufacturers with audio equipment research and development backgrounds have launched their own products. The quality of a music product largely depends on the chip used, and each manufacturer also Everyone does what they can, and the BBK i399 reviewed this time uses Wolfson chips. It is these chips and manufacturers that have promoted the improvement of the quality of domestic music mobile phones. Although this BBK i399 is average in appearance, But it is indeed commendable in terms of music playback, and I believe it will be a good choice for music lovers.
