Let's first analyze the relevant data of young people using true wireless headphones every day. Making phone calls, reading books, studying, watching videos and playing games are important scenes for this group to use true wireless headphones, accounting for a very high proportion of time. These habits can explain from the side that our requirements for true wireless headphones are: high sound quality output, comfortable to wear for a long time, able to communicate with people at any time even when wearing headphones, and high requirements for technology and fashion.
Choose headphones according to sound quality.
Sound quality must be the soul of an earphone. No matter how perfect the appearance is, no matter how good the workmanship is, it is also a cloud without good sound quality. Sound quality is a very subjective standard. Everyone has different preferences and different evaluations of sound quality. In this regard, it is most reliable for e-commerce companies to choose products with appropriate prices and appearance that meet their own requirements, and then go to physical stores to audition and select.
Choose headphones according to the usage scenario.
Headphones can be roughly divided into three types: wearable headphones, in-ear earplugs and flat-headed earplugs.
Headphones: according to the sound insulation structure, they are divided into open, semi-open and closed. The natural sound quality is good, but the sound insulation is poor. Not only the wearer can hear the surrounding noise, but also the people around him can hear the music played by the wearer. Many high-end models are open, such as Senhai hd650, akgk70 1 and so on. Semi-open and closed sound insulation will be better. For example, akgk450 is semi-open, and Boya dt 1350 is closed. If you want to see things in the dormitory without affecting others and don't want to be influenced by others, it is recommended to choose a closed type, or you can choose a model with noise reduction.
In-ear earplugs: Compared with portable headphones, the sound insulation effect is better. The disadvantage is that there may be a stethoscope effect. Generally speaking, the stethoscope around the cord and ear has little effect. The model with heavy stethoscope effect is not suitable for exercise. However, this sound insulation advantage is reflected in the crowded subway and bus.
Flat head plug: the advantage is that the stethoscope has little influence and is easy to carry. Disadvantages: the sound insulation is the worst, the sound is unstable, and the elastic sound worn will be different. Belong to a more moderate choice.
Choose headphones according to personal physical conditions.
Headphones are divided into ear-wrapping type and ear-pressing type according to the way of wearing. Ear wrapping is to wrap the ear like k70 1 above, and ear pressing is to press the earphone on the ear as the name implies, such as k450 and dt 1350 mentioned above. Some people can't wear ear pressure because of their ear shape or head shape. You must try it.
In-ear styles have different calibers, and people with small ear holes will feel pain when wearing large caliber. For example, the models of Intemet and Weston are narrow-mouthed, while some models of ue are abusive.
Select headphones according to the playback device.
I believe that most student users use mobile phones or iPod walkman as players, and these products are not very popular. When choosing, it should be noted that some headphones that need a lot of thrust may not be suitable for their own playback equipment. Those who don't know much about this are also advised to go to the physical store for audition.
What scene is Sony's true wireless noise-reducing earphone WF- 1000XM4 suitable for?
Sony wireless headset WF- 1000XM4 is a very multifunctional headset in my opinion. Since I started it, it has appeared in almost every scene of my life.
Social animals like me, who work hard in big cities, generally live far from their places of work. I go to work not only by subway but also by bus every day. This long commute time will always add some trouble to the noise in the carriage. But with Sony WF- 1000XM4 true wireless noise canceling headphones, it is different. Wearing it, I am in an independent space. In my own small world, I can listen to wonderful music, close my eyes and take a nap. Thank you for your invitation.
Intelligent Noise Reduction Adapts to Various Usage Scenes Evaluation of JBLLIVEPRO2 Luminous Bean Second Generation True Wireless Noise Reduction Headphones
Due to the convenience of use and other factors, TWS headphones have become one of the necessary accessories for our daily use of mobile phones and play a very important role in our daily work and life. In view of the rich usage scenarios of users and the increasingly high functional requirements for headphones, noise reduction, sound quality, call, battery life and other factors have become the factors that need to be considered when choosing TWS headphones. Today, I will share with you a new TWS high-end product launched by JBL-JBlivePro 2 Dazzling Beans II. As a Bluetooth headset that supports active noise reduction, it also provides users with rich function adjustments, further broadening and enriching the usage scenarios.
High-quality drive unit, JBL signature sound blessing
We can directly connect and match JBL Hyun Bean II through mobile phones or other devices to use it. If you want to give full play to the rich audio performance of JBL Xuandou II, you can also use it with the "jbl headphones”APP on the mobile phone. After the headset is connected to Bluetooth, open the APP to automatically identify the headset and enter the setting interface. The first time you use the APP, it will automatically guide you to complete the work such as ear canal scanning, and then the headset will intelligently match the noise reduction scheme that suits you best according to the scanning results. The "jbl headphones”APP allows you to control headphones through functional options such as ambient sound, sound equalizer, intelligent audio-visual mode and gestures.
After adjustment, you can get an audio experience that is more in line with your own preferences. In terms of hardware, JBL Xuandou II adopts titanium alloy diaphragm, which has the advantages of light weight and strong rigidity, and can achieve lower potential at low frequencies, which can make music details more comprehensive. Coupled with 10mm drive unit and JBL signature sound effect adjusted by Harman Acoustics Laboratory, the sound quality is excellent.
After the overall use, the overall performance of the headset is relatively balanced, the default sound mode, and the sound filtering is natural and distinct. After optimization, the dive low frequency is strong and elastic, the middle frequency is soft and smooth, and the high frequency extension is clear. Whether it's metal rock with a beat, or lyrical light music with rich voices and delicate tunes, it can create an atmosphere with high sound quality.
In addition, JBL Hyun Dou II has five built-in audio modes, supports custom EQ equalizer curves, and can also fine-tune preset sound curves to facilitate advanced users to adjust and set their favorite sound modes.
JBL Dazzling Beans II also supports intelligent audio-visual mode, which can be switched to audio mode or video mode according to the actual use state, such as switching to video mode when watching movies, TV series or playing games, which can effectively improve the audio-visual synchronization performance and bring better audio-visual experience.
For Bluetooth headsets, in addition to listening to songs and watching videos, some users may also need to play games. JBL Xuandou II adopts a new generation of high-performance Bluetooth 5.2 chip, and adopts dual-channel transmission+synchronization technology, which makes the connection more stable and the delay lower. Even if it is a chicken-eating game that requires high sound synchronization, it can cope with it freely, and there is no sound delay in the process of wearing the game.
Intelligent adaptive noise reduction
For users who exercise in the gym and work in the office for a long time, in addition to paying attention to the sound quality and wearing comfort of headphones. Among them, noise reduction ability is also a very important function, which can isolate noisy noise from the outside world and make people more focused on their immediate work and exercise. JBL Xuandou II adopts innovative fully adaptive digital noise reduction, which can intelligently and automatically optimize and match the noise reduction mode, and accurately generate reverse sound waves to cancel the noise, thus achieving an average noise reduction depth of 30dB, up to 42db. Of course, users can also manually adjust the noise reduction amount through multiple stages according to their actual use, and manually correct the noise reduction level to suit themselves.
First of all, we choose to take the subway to carry out the actual noise reduction test. Commuting by subway is one of the most common usage scenarios for most users. The noise of cars and voices around the subway is very noisy, and the mixing of different kinds of sounds actually tests the noise reduction ability of headphones. After turning on the noise reduction mode and switching to "ANC noise reduction", you can obviously feel that the environmental noise is obviously reduced.
The two microphones on the outside and inside of JBL Glow Beans II headphones are equipped with digital noise reduction software engines, which can pick up sounds from the outside and inside of the ear canal to achieve better noise reduction. The built-in ANC controller can analyze the environmental noise components in real time, and can automatically adjust and help users choose the appropriate noise reduction mode after it is turned on, which has an effective suppression effect on the noisy environmental sound in the subway.
In addition to the adaptive active noise reduction mode, we can also make multi-level manual noise reduction adjustment, and we can also customize the active noise reduction mode by combining the ambient noise and personal ear canal through the function of "ear canal test" to bring better noise reduction effect.
JBL Xuandou II also supports the function of intelligently listening to ambient sounds, and can also perceive the surrounding ambient sounds while listening to music, so that you can also notice the surrounding vehicles when wearing outdoor sports, making it safer to wear and use; In addition, it also supports one-button switching of "free call" mode, and directly switches to transparent mode, so that you can easily talk freely with people around you without taking off your headphones.
When answering a work phone or driving a phone in a public place, you often miss important content because the surrounding environment is too noisy. JBL Dazzling Bead II solves this problem by reducing noise through three microphones. There is a dual-beam microphone array at the bottom of the ear handle, which can carry out intelligent directional radio reception. In addition, each earphone has a single built-in microphone, which can reduce the wind noise in the surrounding environment. Through the design of three microphones, the call optimization algorithm is optimized to pick up human voices.
In addition, JBL Hyun Dou II has built-in "Tencent Xiao Wei" function. After the device is added, long press the right ear button to wake up the "Tencent Xiao Wei" intelligent assistant. At the same time, the voice function can be set as the default of the mobile phone in the settings, and information can be obtained through voice commands without opening the mobile phone, such as playing/pausing music, switching songs, querying weather, audio on demand and other functions.
appearance design
First of all, let's take a brief look at the outer packaging design. JBL Hyun Dou II has pictures and names printed on the front of the product.

The cover of JBL Hyun Dou second-generation charging box adopts magnetic attraction design, which has a certain damping feeling when it is opened, and can be directly and automatically absorbed when it is closed to a certain angle, so as to ensure that the cover will not accidentally open and lose earplugs when it is carried. The internal earphone slot also adopts magnetic attraction design, which can make the earphone placed more firmly, and directly replenish the power for the earphone after adsorption.
There are three strip-shaped LED indicators in front of the charging box. When the lid is opened/closed, the current power state will be displayed. According to the indicators, we can know the remaining power, charging state and Bluetooth connection of the charging box.
