First of all, thank you Love to play computer games This trial opportunity is provided.

At the beginning, let's talk about two personal views:

1. In the Internet+era, more and more brands begin to choose to extend to the upstream and downstream of the industrial chain, seeking the development model of the whole industrial chain, with the intention of constantly expanding their own resources, markets and brand advantages, for example, PPTV、 LeTV, Hammer and Xiaomi all started from software applications, entered hardware manufacturing, and gradually expanded their product lines to enrich hardware products. This kind of thinking and mode is a good development direction, but we must grasp the degree. If the pace is too big, it is easy to pull the egg, such as LeEco. Today's Kuwo speaker is also an attempt to extend the industrial chain of Kuwo music, an old music playing software, and enter hardware related industries, which is naturally worthy of attention.

2. For some time, the Bluetooth speaker industry has entered into a misunderstanding of homogeneous competition and one-sided pursuit of appearance. Most brands lack the ability and patience to tune the sound quality of speakers. Some flashy functions were added to attract the attention of the public, and the appearance was strange. The Bluetooth speaker market with mixed eyes began to make users lose patience. The Kuwo S7 Pro stereo Bluetooth speaker, created by the veteran music brand Kuwo, also uses TWS split Bluetooth speaker technology, which has injected a clean stream into the Bluetooth speaker market.

The above two points also drive me to experience this speaker. Since the release of the first Bluetooth headset in 2015, Kuwo Music has been committed to creating a high-quality user experience integrating software and hardware. It has successively launched sports Bluetooth headsets, portable waterproof speakers, Bluetooth headsets and other products. The combination of software and hardware has further enhanced the brand's influence. Kuwo S7 Pro stereo bluetooth speakers are one of the few split bluetooth speakers on the market, especially when the price is below 500 yuan. Next, let's walk into the Kuwo S7 Pro stereo Bluetooth speaker.

[Appearance]

In terms of appearance, Kuwo S7 Pro follows the traditional black appearance of the speaker. The frosted body of the aluminum alloy shell looks exquisite. The overall size of the two speakers is 86mm in diameter, 40mm high, and the single weight is only 210g, which looks like two cylindrical cakes.

There is a logo of Kuwo in the middle of speakers, and the edge cutting process of CNC is widely used in products, which makes the black and white outline of products clear, simple and aesthetic.

On the side of the cylinder, the three control keys are arranged in sequence, with the power key in the middle and the volume+/- on the left and right. The operation logic follows the convention, long press the power key to switch on and off, short press play/pause; Long press the volume+/- to play the previous/next song. The keys are marked with grooves, which are intuitive and comfortable.

There is also a small hole for hanging rope on the side of the volume key. You can use the random hanging rope to hang the audio.

The protruding ring at the bottom of Kuwo S7 Pro is made of silica gel, which has anti slip and fall protection functions. Three contacts can be connected and fixed with the base.

The interface of the S7 Pro is hidden below the silicone cover on the back. On the left is a TF slot, which can be inserted into external storage to read internal music files directly for playing. Long press the volume+/- to switch tracks.

On the right is a MicroUSB charging hole. MircoUSB can be used as an independent sound card and speaker for external playback after it is connected to a PC to isolate the complex static environment of the PC motherboard, so as to obtain better sound quality performance.

The product is equipped with two sets of MicroUSB charging cables and lanyards, which are convenient for separate use of speakers.

S7 Pro is equipped with two bases. The design style of the base is consistent with that of the speaker. The front and back sides are made of silica gel, which has a non slip fixing effect. There is a small round concave point on the base, which is used for nesting and connecting with the convex points on the speaker for fixing.

The exclusive base is designed with a small elevation of 97 degrees to improve the sound range. The "bumps" on the main body of the speaker are distributed in equilateral triangles, which means that the speaker can be connected to the base at will, so that the control keys can be placed on the top, left and right sides respectively, which is convenient for control. The design is ingenious.

Core Configuration

The S7 Pro uses a combination of 50mm speakers+45mm bass enhanced radiators, and the front is made of black soft sound cover material.

The 45mm bass enhanced radiator on the back is decorated with concentric circular lines, with L and R marks on it to distinguish left and right units.

In addition, Kuwo S7 Pro has a built-in 1050 mA battery. If you listen to music for 1.5 hours a day at 75% of the power, you can charge it once a week; It can also play a super long record for 8 hours continuously, and its endurance is still excellent.

[Innovative technology]

Kuwo S7 Pro also hides a working status indicator light on the top edge of the front logo, which is very hidden and serves as a status auxiliary prompt.

Kuwo S7 Pro supports three playback modes. One is TWS Bluetooth pairing mode, the other is TF card single use mode, and the third is USB sound card single use mode. In the card insertion mode, after inserting the TF card, start the machine, press the power on key twice to enter the TF card playing mode, which supports 32G TF card at most, and supports MP3/WMA/APE/FLAC/WAC and other popular formats in the market. The USB interface integrates multiple functions. The USB connection for external play and charging is the same interface. Its function is somewhat similar to that of a smart phone. It is also inserted into the USB interface. After starting up, press the ON key twice to enter the USB sound card playing mode.

Here, we will focus on the Bluetooth mode. Kuwo S7 Pro adopts the Bluetooth 4.2 connection standard and is widely compatible with common devices such as mobile phones, tablets, laptops, smart TVs and set-top boxes. It is more compatible, more stable, and more power efficient. At the same time, the Bluetooth 4.0 technology enables the transmission bandwidth to reach 24Mbps, far exceeding the 1.4Mbps required for CD audio quality. Therefore, the Bluetooth 4.2 technology equipped with Kuwo S7 Pro can well complete the transmission of high-definition audio and ensure the stability of the audio source.

Open one of the two speakers of Kuwo S7Pro, and the speaker will prompt "good audio quality, use Kuwo, Bluetooth mode". After that, we open the other one and also prompt "Good audio quality, use Kuwo, Bluetooth mode". After about 3 seconds, the speaker will prompt "Team formation succeeded". At this time, open the Bluetooth settings of the paired device and find the "kuwo S7 Pro" connection in the detection list.

At the same time, Kuwo S7 Pro, as a split dual channel Bluetooth speaker using TWS protocol, applies "true wireless" to the Bluetooth speaker, without any wired connection, and two sets of speakers are automatically paired within 10 meters. TWS protocol allows two Bluetooth devices to form a group to play audio, realizing the separation of left and right channels, and no wired connection is required. At Apple's new product launch in 2016, Apple released the world's stunning "true wireless" Bluetooth headset AirPods, whose core is the split Bluetooth audio playback solution, based on the TWS protocol.

[Sound effect and quality]

Since it is used as a speaker, it is still necessary to speak according to the sound quality and sound effect. Next, Bug Zi selected several different styles of lossless audition music to test the sound effect of this speaker. In general, Kuwo S7 Pro does achieve left and right stereo sound effects in wireless Bluetooth mode. This is a very cool and exciting thing. We can freely arrange two speakers without restrictions and cable restrictions. It is very comfortable to pursue the best sound source location.

From the perspective of the overall sound, the sound analysis is fairly good, the sound is relatively clear, the level is relatively clear, and the sound transition is relatively natural and smooth. When testing the live music such as Hotel California, the level and effect of the live sound field can be basically restored.

When playing Ferry, I felt that the effect was slightly inadequate, and the sound was a little vague, but it was calm and heavy, and the shock and diving were not enough.

The interpretation of pure music is OK, and the sound is more exquisite and pleasant. On the whole, the tuning of Kuwo S7 Pro tends to be crisp and soft, and it seems to lack confidence in its thickness and texture. As a daily listening point of pop music, it is still competent.

When the sound is turned to the maximum, there is an occasional popping sound. In addition, in Bluetooth mode, occasionally there is a stuck connection that is not stable enough. The author is trying to analyze whether it is a compatibility issue. From the actual distance of the connection, it is very strong. In the actual test, the Bluetooth connection can still be maintained and can be used normally when the distance is more than 10 meters.

As mentioned at the beginning, Kuwo S7 Pro, as a product with a full industrial chain layout, is strongly supported by Kuwo's powerful resources. In terms of product marketing and planning, in addition to better and more stable sound quality, we should also consider using the advantages of resources and content to explore effective ways of personalized value-added services.

  In a word, Kuwo S7 Pro is a creative product with great innovative spirit. We look forward to doing better and bringing more wonderful things to our life after adjustment and optimization.
