What phone has the best sound quality?

Pure sound quality! European Sound Chip BBK i399 Mobile Phone Evaluation Source: Tianji.com Mobile Channel 2008-7-25 16: 32: 34 BBK, as the earliest enterprise focusing on the research and development of music mobile phones, its products have always been the representative of music mobile phones, and now it is quite mature in workmanship and performance, especially after adopting Wolfson audio processing chips, the sound quality has attracted much attention. Let's give you a detailed evaluation of this Ou Sheng chip BBK i399! BBK i399 adopts the straight shape that is common in mobile phones. The front of the fuselage is made of aluminum alloy, which looks full of texture, and its panel is made into brushed style, which looks very beautiful. The body of BBK i399 is quite thin, so it can be easily tucked into the trouser pocket in summer without being bloated. BBK i399 mobile phone is equipped with a 2.4-inch screen made of 260,000 color TFTs, and its resolution has reached the size of QVGA(240×320 pixels) which is the mainstream of mobile phones. At the top of the screen is BBK i399 strip receiver, and at the bottom is BBK English LOGO. Because there is no obvious gap between the screen and the metal body, the good side is that it is not easy to accumulate dust and oil, and the bad side is that the screen is easy to wear. Users are advised to attach a screen sticker to protect the screen when using it. The keyboard function area of BBK i399 adopts the design of five-way disks, left and right soft keys plus answer and hang-up keys. Five disks are designed with silver wires, which are more eye-catching on the black body. On the numeric keyboard, BBK puts the three keys of "*", "0" and "#" on the right side of the keyboard, which will take some time for friends who use this mobile phone for the first time. The key stroke is moderate and feels comfortable. The periphery of the fuselage is very simple, using piano paint, and the feel is very smooth. The red metal edge adds a little vitality and charm to the black body, so that the whole mobile phone will not be too monotonous. There are no buttons on the side and only one USB jack on the bottom. This setting is rare in the current "land-intensive" mobile phones, which is very concise and lively, but it may bring some operational inconvenience and advantages and disadvantages. The back design is also very simple, with only a 2 megapixel lens and speakers. Although it is made of plastic, it feels quite delicate after frosting. Because the lens protrudes from the fuselage, it is easy to wear, so be careful when using it. Appearance summary: The first impression BBK i399 gives the editor is that it is relatively light and thin, and with relatively exquisite materials and workmanship, it feels very comfortable to hold it in your hand. The key setting is traditional and simple, especially the key can't be found in the scheme at the edge of the fuselage, which increases the feel and brings some tedious operation. Generally speaking, it's not bad. The screen of BBK i399 is a QVGA screen with 260,000 colors (240× 320 pixels). The display effect is quite good, the color is saturated, and the text clarity is also good, but the resolution is average, and the font is still slightly burr and not delicate enough. BBK i399 still adopts the nine-grid menu mode, and the menu icons are refreshing and stereoscopic. The phone book of BBK i399 mobile phone adopts the business card design, and information such as name, telephone number, e-mail, fax number and company name can be stored in one phone book, which is more comprehensive. And support custom ringtones and pictures, which can give us more DIY space. I399 provides us with storage space of 1000 telephone entries, which should be enough for ordinary users. At the same time, the phone book group function provided in the mobile phone allows us to better manage the phone book of i399. On the dial menu, i399 is relatively simple, and the white background with the numbers in large black font can make people see it clearly. In terms of short message input, BBK i399 supports smart pinyin and stroke input, with good speed, and the mobile phone itself can accommodate 300 short messages. In addition to SMS, BBK i399 also supports email and push inbox, which is undoubtedly very practical for business people and conforms to the development trend of mobile phones as portable network terminals. The overall framing is smooth and slightly smeared, and at most 1600* 1200 photos can be taken. From the imaging effect, the color of the photo is better, but the clarity and sharpness are slightly worse, which is also related to the lack of autofocus of the lens, but it is enough to meet the needs of ordinary users as a whole. Options, including exposure compensation, continuous shooting, white balance, night mode, etc. , are relatively rich. In camera shooting, you can shoot MP4 video files with the size of 352*288, with adjustable options such as white balance, night mode and special effects, and the playability is not bad. In terms of video, this phone also has a built-in independent video player, which can play MP4, 3GP, AVI and other video formats. The fluency is satisfactory, but this phone does not support video playback of QVGA size, and supports full-screen playback. Audio playback is believed to be the biggest concern of everyone and the biggest attraction of BBK i399. Because of the Wolfson audio processing chip, we are looking forward to the performance of this phone in audio. Wolfson's friends who are familiar with the MP3 market should not be strangers. Due to cost and other factors, well-known brands including Meizu have replaced Philips chips with Wolfson chips, and a considerable number of heavyweight products including Sony PSP and Microsoft Xbox have chosen Wolfson. It can be seen that Wolfson's advantage is not only in cost, but also in performance. In standby mode, pressing the round key in the middle of the round navigation key supports entering the shortcut mode of the music player. We used Cai Qin's "Ferry" as a audition song to test the audio effect of BBK i399. The playing interface is simple and elegant. Judging from the performance effect, the vocal performance is quite excellent, the treble is clear and transparent, the alto is euphemistic and true, and the bass part is slightly insufficient, but the overall performance is acceptable and commendable. In the tool column, we can see the learning world, common tools and games. The world of learning is mainly English words and vocabulary of various exams. Built-in repeater function, I believe it is very suitable for students and friends. Among the common tools, you can find calendars, alarm clocks, memos, etc. To facilitate the daily needs of users. There are two games built into the mobile phone: Stack Square and Super Circle, which is not bad in playability. Value-added service provides the contact information of BBK mobile phone after-sales service all over the country, which is convenient for users to consult and ask questions. Very considerate. The battery life BBK i399 is equipped with an 800 mAh lithium battery, which is quite common for a music mobile phone. Fortunately, BBK i399 has a good battery life, and a battery with the same capacity is sent randomly for standby. During the evaluation period, 30 minutes of telephone calls, 10 short messages, 2 hours of music and 5 photos were made every day. It took about two and a half days, so I need to bring a spare battery. Evaluation summary: Nowadays, mobile phones seem to have an upward trend again. Many manufacturers with audio equipment research and development background have launched their own products. The quality of a music product depends largely on the chips used, and each company has its own capabilities. The BBK i399 evaluated this time uses Wolfson chip, which has promoted the quality improvement of domestic music mobile phones. Although the appearance of this BBK i399 is moderate,
