This year's dark circles audio circles, how much do you know about true wireless Bluetooth?

Once Xiaobian heard an unidentified Hong Kong buyer at a show to the effect that young Hong Kong people nowadays are willing to spend some money to buy something they want to please themselves. , Headphone is a good choice.First and regardless of geographical differences, but in recent years we can indeed see many of my friends will be the headset as a just-needed, choose your favorite style, the pursuit of their desired quality.

The Bluetooth headset because of its structural advantages, combined with the young people now use headphones for a long time outside the scene characteristics, by young consumers wide attention in the promotion of major e-commerce platform, increasing the material requirements However, many of my friends want to buy a 'wireless headset', in fact, not a true wireless headset.Head-worn true wireless headphones may be commonplace, but in-ear, the so-called 'real wireless headset '(TWS for short) Maybe everyone knows about airpods, but is it enough for you to know about such new gadgets?

What is a true wireless Bluetooth headset?

Maybe some friends will feel puzzled, this 'Bluetooth headset' and 'wireless headset' What is the difference? Many of my friends will say that many Bluetooth headset is wireless, but the traditional in-ear Bluetooth headset on both sides of the unit or a cable Audio signal transmission.That is, with both sides of the in-ear Bluetooth headset with cable can work simultaneously, like a Bluetooth speaker, in-ear Bluetooth headset can be transmitted through the cable, making both sides of the ear steady and steady sound , But this only saves the line of headphones and audio only.

And represented by AirPods true wireless Bluetooth headset, it is further subtraction, but also means that there are differences between the working principle.Real wireless Bluetooth headset will be the main and auxiliary headphone, the connection needs to launch equipment ( Phone, tablet, music player with bluetooth output, etc.) Connect with the main earphone first, and then connect with the subwoofer after the connection is established. Only after the connection is completed can it work normally.

In other words, compared to the traditional 'wireless headsets', the connection of the true wireless headphone is not only the signal transmission between the headphone and the signal transmitting device, but also the wireless connection exists between the main and auxiliary headsets. Compared with the traditional wireless headsets, More complicated headphone structure, high transmission requirements, power consumption, these elements of the final sound effects will be more obvious, the general phenomenon is: true wireless headset sound quality is slightly worse than the same price Bluetooth headset. Since there are many disturbing factors , Why do you really wireless headphones?

The traditional in-ear Bluetooth earphones all have a wire connection, which makes them even though they have got rid of the physical connection with the sound source. However, the wire between the two earphones still brings some interference when worn, Typical example: The traditional Bluetooth earphone can not handle the auscultation effect especially when the body needs exercise such as exercise, etc. Of course, this is not limited to this, and the line in the middle is less, and for games and user degrees of freedom Come, true wireless headphones on this part of the experience will bring significant improvement.

However, there is a problem with the true wireless Bluetooth headset

If so, I believe there will be many manufacturers will follow up the launch of TWS products.For this product form is more interested in the market may be in foreign countries, perhaps crooked nuts pay more attention to sports, exercise time and opportunities more However, as Xiaobian mentioned above, the true wireless headset to make comparable to the original in-ear Bluetooth headset effect, to face the problem really is not so good solution.

Popular in the audio ring with a sentence, 'play HiFi first play electric'. '' For the Bluetooth headset, not only related to battery life, but also means that it can provide sufficient power to support the normal operation of the internal circuit. In addition to the original signal receiving module and decoding amplification part, there is a connection between the main and auxiliary headphone circuit. Three parts work at the same time, the battery requirements are also increased accordingly. So we can see the current wireless headset Time use life will not be too long, most of which is about two hours, and basic with the battery containing the storage box to use, in order to ensure adequate life time.

However, even if at this stage to space / battery problems, Bluetooth headset has been criticized 'transmission problem' is the most troubling place.Some friends may say Qualcomm aptX, Sony's LDAC, is not for Non-destructive music technology introduced? Indeed these two technical standards for the transmission of non-destructive music has been greatly assisted, but now have access to these two technologies and how much of the product? Moreover, the two technology current audience, Nor is it mainly aimed at the true wireless headset.According to Xiaobian online survey found that many current wireless headphones are still the picture is not synchronized, easy to break and other transmission problems.

To solve the problem of reducing the user experience like these, we may have to wait until the Bluetooth 5.0 specification chipset solution is officially launched, except that the fastest shipment is the CSR solution launched in the first quarter of 18th. Universal access, for the category of audio products, a year and a half is also a normal thing.This makes the true wireless headset user experience in a short time there are flaws.Of course, there are still manufacturers at this stage Bluetooth 4.0 specification On the basis of independent research and development technology to ensure the stability and synchronization of transmission rate.

We can understand that the number of mobile phones that support the Bluetooth 5.0 specification is not much. That is to say, the number of mobile phones supporting the iPhone 5.0 specification is also less than that of the iPhone 8 and a few flagship Android models (such as the Samsung S8). Both the headset and the audio source Support for the transmission specifications should complement each other.Although the speed of mobile phone replacement, maybe the Bluetooth 5.0 specification to be more popular than the true wireless headset to be simpler, but this process takes time.

In general, the existing Bluetooth transmission norms still failed to meet the transmission stability, as well as lossless bandwidth required for music transmission.When using the Bluetooth 5.0 specification chipset has become popular, the corresponding component prices lower, the true wireless headset has To survive in the market.When this happens, if the stagnant civilian battery market is still a long time can get a major breakthrough, the real wireless headset naturally more powerful.

The key question: Should you start really wireless Bluetooth headset?

So, the Bluetooth 5.0 program in the wireless headset and mobile phones have not yet reached the premise, is it worthwhile to start a true wireless headset? Flip Taobao we can find that now the choice of true wireless headset does not seem to be much, Traditional audio manufacturers will still focus on universal Bluetooth headset, and more consumers are indeed attracted to them. So if you want to go in the trend of cutting-edge, what is the real wireless headset is optional? For example, be outside Media evaluation for Apple users most satisfied with the product - airpods.

Careful scrutiny airpods product form can be found, this is not just a true wireless Bluetooth headset, it is more an Apple user-specific communication. No matter where, as long as there is a hand on the Internet with Apple devices, share iCloud Account open all devices on the information notification, carry and open the airpods networked with the device on the body, you will not miss the message, unless one of the depleted battery.In addition, although airpods not equipped aptx or LDAC, but looked like earpods The airpods, but a little improvement in sound performance.

In contrast, some models Xiaobian is not very recommended, the typical example: Sony WF-1000X. Not to mention WF-1000X kind and did not promote the picture so small, the size of the Apple AirPods even larger this point ( After all, comes with noise reduction, the internal circuit a little more is normal.) More importantly, there are already many users react: WF-1000X has a very high probability of instability in the case of walking or low battery. Delay is already commonplace, disconnection is more often occur. Specific details can refer to "Sony WF-1000X true wireless Bluetooth headset evaluation experience before buying must see."

Write at the end: To be wireless? Suggestions wait

Above we mentioned the iPhone X, in this year's double eleven, iPhone X has a wave of 8XXX promotional market, this information makes a lot of friends picked up cheaper to use the iPhone X. iPhone X brings not only full screen Shock (some friends may think there is a bangs considered a full screen), followed by a series of technological innovations, but also be able to promote the development of different industries.Hidden in the iPhone X Bluetooth 5.0 specification body, the audio Industry, especially the development of wireless audio products, is a milestone in the same sense.However, this is only a side from the boost, the development and popularization of true wireless headphones, is a need to work together in many ways to supply soil growth How fertile the soil is, how many other forces will be affected, it is unknown and dangerous.

Perhaps nowadays, when it comes to 'wireless headsets,' it is still premature for consumers to think of a wired Bluetooth headphone. Perhaps it is still too early to say whether wireless headsets are suitable for mass consumer use - after all, the industry itself is exploring And wait. Bluetooth 5.0 for the industry and the market will be an opportunity, the headset in the hands of consumers now just called the product, but the future of true wireless headphones will be, now can only give a 'thorn in the development' to Looking forward.

By the way, make a small advertisement, Lao Huang has recently collected a number of true wireless headphones to do comparative testing, interested friends can pay attention to PConline peripheral channel is about to bring 'real wireless headset Hengping!
