The wireless speaker connection is still based on Bluetooth, but the loss of the transmission process is inevitable, and WiFi has a superb bandwidth, can reach a very high standard in the transmission of music, you can enjoy a good sound of more fever .
Let's share with you the Sony h.ear.go speaker that I recently started. Honestly speaking, this is not a wifi-based speaker, but it uses various wired and wireless connection methods. It also supports various special effects of Dafa: LDAC, S-master, DSEE HX and so on.
In addition h.ear.go offers five colors: green, lemon yellow, Bordeaux red, cinnabar red, carbon black.
===================================
Packaging and appearanceThe color of the box is based on the color of the speaker. This is green (I feel a bit like blue), so it is a green and white box.
As mentioned earlier this speaker is wireless/wired-take-all, Bluetooth, WIFI, USB DAC, AUX input.
The lower left corner also introduces a bunch of special effects:
Hi-Res Komatsu certification: high-resolution audio, can show the ultimate music quality and original sound reproduction. Of course, it is also proposed and defined by Sony to draw up several high quality audio product design standards developed by related associations.
LDAC Technology: Technology to improve Bluetooth sound quality (so that this speaker did not forget Bluetooth, after all, the most popular thing!). The highest sound quality can reach 990kbps. Under optimal conditions, the data transmission capacity of LDAC technology can reach three times that of existing SBC or AAC technology. The official statement is slightly!
EXTRA BASS, a stuff that adds bass.
The h.ear.go model is the Sony SRS-HG1. On the back, it introduces a bunch of special effects. Of course, there are duplicates of the previous information.
SongPal Link: Use the songpal APP to combine multiple Sony speakers into a wireless surround sound or to achieve a doubled sound field through two speakers, a great way to promote your own speakers.
It looks like this is the first Sony product to support the USB DAC wireless speaker, so the back side has specifically written support for the USB DAC.
Also: Support Bluetooth 4.2 in hardware, support encoder SBC/AAC/LDAC; digital audio architecture uses S-master HX digital amplification chip; support DSEE HX technology (software algorithm) babababababa, etc., in short, a considerable amount of information . 
There are not many accessories for h.ear.go, only the charger (the charging cable can be used as a USB DAC data cable), manual, user guide, warranty card, and even AUX cable.
The packaging is still very safe, with two layers of foam.
The design of h.ear.go is very simple and the workmanship is still good, after all, the price is over 1k. Dafa's LOGO is in the middle position. 
The keys are on the top, but not all the keys are here, and there is an NFC antenna on the top.
Top button: Power button (with two indicators, the power indicator and Bluetooth pairing indicator); volume up button and volume down button; EXTRA BASS is bass button with indicator light; the last one is used to connect Hang up the button for the phone. 
There are also many function keys on the back.
The lower left corner is the charging Micro-USB interface, DAC Micro-USB interface and AUX audio input interface.
Since there are two Micro-USB interfaces, the location of the charging port has been specifically marked for differentiation. This is a careful point. If you insert the wrong port, you may damage the machine. 
The bottom right corner is the R/L indicator (two left and right channel speaker combination indicator), STEREO PAIR button, SET UP button, and upgrade/WPS button. The purpose of these few keys has not been found yet. It should be multi-speaker mode. Use it under. 
The Function key bit is used to switch the connection mode (network/bluetooth/usb/audio in), and each has an indicator light below.
There is also a combination of skills: Press and hold the volume-button and SET UP button to observe the strength of the WIFI network signal, and display the signal strength through the five status lights (link indicator of the link/network/bluetooth/usb/audio in). 
H.ear.go has four feet on the bottom, in order to cushion shocks.
There is a restart button that can restart in case of a crash. There is the basic information of the product, the origin is actually not China!
The front metal panel (which should be magnetic) can be removed by pushing the button on the bottom side, and the unit of h.ear.go can be clearly seen: two full-frequency units and one passive diaphragm (bass unit).
The dual full-frequency unit is 35mm, made of a high-rigid MRC (foam mica vibrating diaphragm) material diaphragm and a ferromagnetic material, which can achieve a 40kHz frequency response coverage from low to high frequencies.
The speaker cabinet was made of high-rigidity resin material, which increased its strength. However, honestly speaking, picking up h.ear.go for the first time still felt that such a small stuff was quite heavy.
The skin was treated on the surface to feel good. The disadvantage is that the oil in the hand easily left fingerprints and traces of oil. 
The corners were treated with shrinkage and rounded chamfers, and they were wrapped in metal to make the lines clearer. 
The adapter model is AC-UUD12, voltage range 100v-240v, output is 5V 1.5A, power is 7.5W. Origin is the Philippines, and the speaker itself is not the same place of origin.
The volume of h.ear.go is approximately 204mm long, 62mm high, and 60mm wide. It is approximately the size of a 550ml mineral water bottle. It is relatively easy to carry and weighs approximately 790g. Such a small thing is quite heavy.
Built-in lithium battery, the official introduction of life time is about 12 hours, how is the continuous call, can use 4 hours; if no operation or play songs for 15 minutes, it will automatically shut down. If you do not use it after 30 hours of shutdown, you need to press and hold for 15-30 seconds or directly connect the charger to boot.
====================================
SongPal settingsThen introduce the connection method:
The simplest way is NFC, put the mobile phone directly on the speaker, you can immediately play the songs in the phone, of course, your phone has to support NFC.
The most common method is still Bluetooth, and you can pair the new device by pressing and holding the power button for about 5 seconds.
Of course, the biggest feature of h.ear.go is still through the WIFI network link. After all, the loss of the connection sound quality in this way is the lowest. This will be achieved using the SongPal APP.
It is recommended that Bluetooth be paired before pairing with WIFI. Of course, pairing is also possible. After all, the Bluetooth connection is also very difficult to use.
Open SongPal and pair it: The middle also reminds you that multiple Sony wireless speakers can be used to form a system through SongPal. Buy and buy the rhythm!
It is best to connect the mobile phone close to the speaker for the first time, h.ear.go supports 2.4/5G WIFI band, enter the password of good wifi, point to determine, establish a good WIFI connection, the connection process is not too much trouble. 
After entering the software to connect the device, you can see several interfaces: My Muisc, USB DAC, Audio in, Home Network, and settings.
My Muisc is the music in the cell phone.
The USB DAC, Audio in, and Home Network are the switching input modes. The function is the same as the FUNCTION button.
Sound Adjustment In settings, the equalizer supports four sound effects and custom five-band EQ adjustments.
Only FLAT mode supports ClearAudio+; EXTRA BASS also has buttons on the speaker that can be turned on.
DSEE HX: It can effectively repair the treble distortion caused by the compressed sound source, but it is said that it will consume more power when turned on. 
Settings also include: power options; other settings and systems.
You can check the power level in the power options, but some phones will display abnormally. My Huawei's mobile phone always shows 10% of the power, and another phone can display normally.
Other settings: Bluetooth codec can choose automatic, that is, Sony advertised LDAC or traditional SBC.
Click on the 3 small dots in the upper right corner and there are other features such as shutdown, add application level, and more.
After adding the application, the application will enter the main interface, but after clicking it will automatically start the Bluetooth connection, so it is of little use. 
When connected, you can turn off the Bluetooth, you can still control the speaker through wifi, after all, even if the LDAC sound quality is still lost, so it is devaluation wifi connection.
The software function is still under study, but still found some problems. It is of course no problem to use My Muisc to play music over wifi, but when playing some lossless format (ape, flac) can not be played, there is no problem to change a mobile phone, but It is quite strange to use the music playback software that comes with the phone to play it.
Third-party music player software (qq music, cool dog music), can only use Bluetooth connection, also mentioned in the previous even after adding the application is also the case, some people say that qq music Qplay can achieve wifi connection, but I After the attempt was unsuccessful, the speaker device could not be found, but it seemed that someone had succeeded.
Music does not matter, after all, you can find it in My Muisc. However, SongPal did not come with video software, watching video can only use third-party software, so you can only use Bluetooth connection or wired connection, and can not use wifi connection.
On the whole, the setting of SongPal software is fairly simple, and the operation is also easy to use. It may still be a bit of a problem with compatibility. I would like to expand the application range of the wifi connection that manufacturers need to continuously strengthen.
=====================================
Sound quality feelLet's talk about how SongPal offers 4 different equalizer styles (no custom EQ)
I debuted the FLAT+ClearAudio+ mode, which is also a relatively balanced style. The vocals are clear and can guarantee a certain degree of resolution and realism.
EXTRA BASS is the main low-frequency enhancement technology. The bass is strengthened and the dive is more complete. However, the human voice is slightly distorted. In addition, the sound of the soundtrack is rich or the scene will be slightly mixed. I think that in addition to specific music and like this Kind of style, it is not recommended to open.
OUTDOOR is a much louder sound. From the perspective of English, it is also recommended for outdoor use. However, the sound is loud and the details are missing.
BGM, the official said that the increase in sound pressure, to achieve a better pure music listening effect, but I feel the soundtrack and vocals are weakened, nothing special feeling.
In addition, although Sony said LDAC's Bluetooth decoding method to reduce the loss of sound transmission, but I still feel better wifi connection, compared to the Bluetooth connection, wifi connection resolution and realism is better, the sound is clean, There is less sound and the noise at the bottom of a complex or high-pitched tone is almost inaudible.
The following is still talking about sound quality through some different styles of lossless audio. 
Avril Lavigne, for this lively punk rock style, the dynamic performance is good, the blow is also very good, partial to the popular songs can deal with.
Michael Jackson, fast song has good dynamics and rhythm, bass is also thick.
Whitney Houston, for such a strong European and American style, the tone of the sound is not very heavy, the vocals are clean and true, and the treble part is also good, which can guarantee a certain degree of resolution and realism.
Jay Chou, for some music scores is relatively simple, the performance is better, the voice is also more forward, the music is also clear; for the rich music, the level of feeling I think above the pass line.
Tsai Chin, the voice of Zhongyin is delicate, moderate and moderate, and the sound is relatively strong. .
Hisaishi Jean's "Sky City Movie Original Soundtrack" has moderate stretch and brightness when there are few musical instruments, and it can guarantee a certain sense of depth and resolution in the face of grand symphonies, but it loses slightly in the sound field momentum.
===================================
H.ear.go this speaker wifi connection is the biggest bright spot, after all, Bluetooth advantages over bandwidth and transmission distance, can provide better sound quality. Of course, the wifi connection needs a wifi environment. It is good to play at home, and the outside environment can be difficult. Even places that provide wifi will worry about security issues.
Due to the limited use of wifi now, I'm afraid there is no wireless speaker product that will give up Bluetooth connection technology, so does h.ear.go, and it also uses its own technology to improve the sound quality of the Bluetooth connection.
In general, Sony h.ear.go speakers can not fully take over the wireless speaker products in the era of wifi connection, or provide a wealth of connections, users can choose. The songpal software for WiFi connection is also relatively simple to set up and use. It is expected that it will be further advanced in terms of functionality and compatibility. In addition, the portability of this speaker is also good, the volume control in such a small, the volume is not small, there is a louder volume Auntie mode (outdoor), at least the volume can be guaranteed. The interconnected mode of multiple speakers should also be very fun, but it looks like a pit, after all, a Dafa speaker is not cheap.
We must say that the disadvantaged price is definitely the biggest factor; EXTRA BASS is a double-edged sword, which has a side effect, and I don't like it anyway. Because of the many functions, the keys will be much more obvious. Inevitably, it's a bit confusing; the wifi connection must go through the APP (the wifi connection products are now like this), if you want a simpler product, h.ear.go may not be suitable for you.
This series features transparent LED screens, which are suitable for various indoor places and various stores, especially in storefronts with floor-to-ceiling glass windows. Installing the transparent screen against the glass wall has a very good effect. When the display is turned off, the audience can watch the indoor environment from the outdoors, and when the display is turned on, they can directly watch the content played on the display.It not only preserves the visibility in the store, but also can effectively display advertising videos to the other party, which is very practical.
