If you have heard of BOSE speakers, JBL audio should also know something about it. JBL is an American brand, a professional research speaker brand and the largest professional speaker manufacturer in the world. From raw materials to speakers, to the design and production of speakers, they are all responsible for their own brands. Like landscape speakers, it has been world-renowned for more than 70 years and is the real big brother in the speaker industry. In the 1970s and 1990s, hardly any brand of speakers could really match it. The series 4343, 4344, 4425 and K2, once created, can best represent the professional audio level of JBL audio, but now they are out of print and have become the treasures of audio lovers all over the world. JBL audio is mostly used in large-scale audio projects, large-scale mobile performances, recording studio monitoring, band use, or cinemas, and then began to develop in the direction of civil audio, such as home audio, discos, dance halls, bars, karaoke and other entertainment places. JBL audio can be seen everywhere. With the development of the audio industry for decades, the only unchanging original intention is to "produce excellent audio products".

What is my understanding of the above passage? JBL audio can develop in this industry for more than 70 years, and its professional strength is definitely not empty. Internet search can also generate a lot of praise. I don't know how other countries react. At least in today's China, the popularity is quite high. If JBL belongs to any grade, I think it is not an exaggeration to call JBL a professional-grade audio.
Next, I will share my personal feelings about the use of audio and my understanding of JBL audio, hoping to help you buy audio.
JBL sound sharing
At present, several models of JBL audio have been popular on the Internet, such as JBL PULSE3 Music Pulse III, JBL GO2 Music BRIC II, JBL SD- 18, JBL CLIP3 Wireless Music Box III, JBL Tower Intelligent Wireless Bluetooth Speaker, etc. These models are all home speakers (which can also be carried outdoors). For general application scenarios, such as listening to songs, watching movies and watching TV, the amplification effect and sound quality are good. Quote the words of netizens as "reliable quality, authentic sound quality and affordable price".
Among them, the second generation of JBL GO2 music BRIC should be the highest among the public, with nearly 200,000+online.
It's very similar to the stereo I use in my dormitory now. They are small and portable, not heavy, not big, only 270.00g, which is half a catty. The material is metal+rubber, which is the same as mine. You can pick it up with one hand, take it anywhere you want, and use it as a portable machine.
In addition to listening to songs and amplifying, JBL GO2 also has voice calling functions, such as WeChat voice and telephone. But be careful. If you really want to answer the phone, you'd better turn off the Bluetooth stereo, otherwise everyone downstairs can hear your phone conversation with each other. If young couples say "sweet words", people will blush.
Although small, the "vital capacity" is not small. Like my small stereo, it is placed in a room and a living room (about 35 square meters). I put it in my room and people listened to it in the toilet with the door closed. It doesn't need to be loud, it's loud enough. If you hear it within half a meter, the sound effect is clearest and most beautiful. As for JBL GO2, some people commented that even in a classroom that can accommodate 80 people (estimated to be 100 square meters), the students in the last row can hear clearly. Then I think it's big enough.
The upper frequency limit of JBL GO2 subwoofer is 180 Hz, and the frequency response of sound is between 180Hz and 20 Hz. The sounds heard in this range are very rich and clear and natural. Moreover, the signal-to-noise ratio of JBL GO2 is greater than 80dB, and the sound quality at this signal-to-noise ratio value is generally good. In the actual experience, the sound quality of sound transmission is clear and pleasant, and there is no noise. Whether listening to rock music, pop music, pure music or piano music, the sound quality is not bad.
Recently, I was brainwashed by the song "The Wind Blows". I listen to it every day after work, or listen to it in cycles. I love listening to the music adapted by Mike at the beginning, which makes people miss it.
Mine is similar to the one above, the color is silver, and the surface layer is also grid-shaped, but the shape is different. This JBL GO2 is square, with an integrated body and rounded corners. The workmanship and texture look much better than mine. It also has many function buttons, such as volume up and down buttons, pause answering and go to the next button (which can also be used as answering and hanging up buttons), as well as on-off buttons, Bluetooth buttons, audio input ports and charging ports, which are located on the side of the fuselage.
I think this design is very humanized. Because my on-off key and volume up-down key are at the bottom, and they are cylindrical. Sometimes you have to adjust the volume and turn it up, and the interface is not good when charging. Unless I stand it upright, it is easy to overturn (I described it like this, and I believe everyone can imagine what it looks like)
However, it is a bit bad to connect with Bluetooth, such as mine, because it is connected through Bluetooth. If my mobile phone is more than 3 meters away from the stereo, the sound will be intermittent. JBL GO2 is suitable for many scenes, such as playing English audio in the classroom, taking it outdoors to run, putting it in the corner of the bed to help you sleep, or taking it to take a bath to entertain you. Adopt IPX7 waterproof design to meet the interest of listening to songs in the bath.
Choi * * * 12, each of which is a young person's dish. My favorite colors are blue, orange, red and light green. They are beautiful and fashionable.
Personal point of view
After all, JBL GO2 is not a senior speaker. Only suitable for people who like listening to music and don't pursue high sound quality. If you only care about convenience, JBL GO2 is a good choice and the price is not expensive. It can be purchased at the price of 199. If you are a fever-level crowd pursuing high-quality sound effects of HIFI, JBL GO2 can't satisfy it. No one will expect a stereo less than 200 yuan to produce high quality sound quality. ...
JBL is the largest professional speaker manufacturer in the world, and JBL has accumulated a large number of technical barriers in the production process of one hundred years.
1. In terms of feeling, JBL speakers give people the impression of wide frequency response, great dynamic, and strong high and low frequency sound performance, especially professional speakers, JBL's early 4-series monitoring speakers, with superior plates, neutral timbre, health and rich atmosphere.
2.JBL tone is characterized by high receiving power, between 200-300 W; High flexibility, high sound pressure level above 1 10dB; Good frequency response, flat frequency response and excellent transient characteristics.
3. Flat wire voice coil is an advanced technology invented by JBL company. First used in woofers, then widely used in tweeters, both aluminum and copper. Flexible flat cable has a high duty cycle, and the application of magnetic gap aims at improving flexibility. According to the test, under the same magnetic circuit, the flat wire voice coil can improve the flexibility by about 1dB compared with the round wire voice coil.
4. The spherical top unit of titanium diaphragm is also the first success of JBL Company. The Young's modulus of titanium data is better than that of aluminum data, and the upper limit of high frequency can be greatly widened and the power capacity can be greatly improved by using titanium film high-frequency speakers.
5.SFG symmetrical magnetic field magnetic circuit titanium diaphragm is a patented technology of JBL company. This patented technology ensures that the distribution symmetry of FB value on the magnetic gap is equal to the upper and lower positions of the voice coil, including magnetic flux balance, reducing the inductance of the driving source, heat conduction and other structural settings. Effectively suppress low-frequency distortion and improve power acceptance and damping characteristics.
Seeing this question and answer, I was immediately afraid of a photo of JBL Bluetooth speaker. The top is the speaker, and the bottom is the 5-inch discarded mobile phone for size comparison. This speaker is about the same length and slightly thicker than the thermos cup you usually carry with you. I bought it for five years, and the price at that time was 1400 yuan.
With such a small speaker, the power of 20W, dozens of people can be the speakers of the square dance, using mobile phones as the sound source (the sound source is lossless music), playing with Bluetooth, and putting it on the park lawn, 20 meters around. Bass (such as drums) is strong, and such a small volume speaker was unimaginable in the past. The treble is slightly insufficient. On the whole, the sound quality is much better than those big speakers in square dance. Someone is dancing square dance in the park. When they heard my speaker, they all praised it.
Of course, there are many speakers with better sound quality than this. You get what you pay.
Disadvantages: Like the mobile phone, it has a built-in folding battery. Now the battery is not enough, and there is no place to change it. Equipped with a charging treasure, it can still be used.
JBL is the world's largest professional speaker manufacturer, and everything from raw material development, speaker unit design and production, speaker design and production can be completely controlled by itself. JBL speakers have a wide range of services, including cinemas, large-scale sound engineering, large-scale mobile performances, recording studio monitoring, audio used by bands, and even entertainment places such as discos, dance halls and karaoke ... In civil use, JBL can be seen everywhere from the most advanced fever audio to the most popular home theater combination ... Its professional quality has reached a certain level.
Not bad, this brand is also an American giant. There are Bluetooth speakers and headphones at home, which are very easy to use and worth buying!
Look at the price, listen to the cheap and listen to the expensive.
The magnetic pole core of jbl low-frequency speaker for sound is quite thick, and the magnetic pole core is hollow, with wire cutting inserts embedded in it. This specially designed magnetic pole core can reduce the weight of the speaker, which is beneficial to heat dissipation and aims to improve the power acceptance. Jbl successfully trial-produced titanium diaphragm dome unit for the first time, which is also a pioneering work in the audio industry. The Young's modulus of titanium data is better than that of aluminum data, and the upper limit of high frequency can be greatly widened and the power capacity can be greatly improved by using titanium film high-frequency speakers.
