The first Bluetooth Jabber 5.0 headset Jabra experience: There are advantages and disadvantages

When consumers are still immersed in the popularity of Bluetooth audio products under the dedication of manufacturers, and bring convenience in different usage scenarios, the Bluetooth specification has quietly reached the 5.0 era. Not to mention the current mobile phones have gradually spread out. Bluetooth 5.0 specification support, as the industry giant, Qualcomm released a series of devices for different devices on the CES2018, Bluetooth 5.0 specification chip, and even released a true wireless headset products that support the Bluetooth specification 5.0.

In the current consumer environment, both the audio manufacturers and the consumers, although they have different perspectives, they all hope that Qualcomm’s Bluetooth 5.0 chip will be launched, allowing the actual end product to have a legacy. A completely different performance. Therefore, when the first true wireless headset with the standard Bluetooth specification 5.0, the Jabra law (hereinafter referred to as the "rule of law") was delivered to the PConline evaluation room, we also had a certain amount of this product. look forward to.

Not only us, you must be reading this article. There is a lot of curiosity about this commercially available Bluetooth 5.0 headset that first appeared in public. Therefore, Lao Huang decided to change his perspective. Simply answer your questions.

Which chip does this headset use?

Huang Huang has read the parameters of Jabra's official website. There is no specific explanation for the chip used. However, there are two groups of chips currently sold by Qualcomm for the receiving end, namely CSR8670 and CSR8675. In terms of parameters, two chips There are still some differences. The most influential options for audio transmission are CSR8670 supporting 16-bit music files, and CSR8675 supporting 24-bit music files. This is not only a difference in audio decoding support, but also means whether the law supports LDAC. The problem with this format is that, as of press time, there is no detailed information on the official website of Qualcomm and Jabra.

To explore this issue, Lao Huang will use different devices, including the famous 'black brick' NWZ-1A, to evaluate the rhythm in the next evaluation.

With the iPhone will not lose sound quality?

There is already a lot of discussion on the topic of 'AAC and aptX sound quality is better'. Although there is Bluetooth 5.0 blessing, but one of the output of this evaluation, iPhone 8Plus, due to format reasons, Whether or not the law will affect the sound quality, we may all have expectations. On this issue, in the subjective listening session, we will also make in-depth comparisons.

How about endurance and transmission stability?

The other aspect of Bluetooth 5.0 is that compared to the previous Bluetooth 4.0 specification, there has been considerable progress in endurance and stability. After some products had successively blew out stability issues, consumers were not aware of the real wireless headphones. Transmission stability has shown concern; AirPods is a life-long voyage in the current true wireless headset market, and it is for consumers to look forward to whether other brands will follow up. What are the two key factors affecting the experience? The experience session will also be answered in detail. However, as far as Lao Huang's feelings of use are concerned, the performance of the paradox is sufficient for daily use.

Take a look at this Bluetooth headset?

After simply answering the three questions, let's take a look at the performance of the headphones from the perspective of traditional evaluation. The first is the outer packaging, Jabra still applied the previous minimalist style, presented in a gray background color The hard-to-be-sounding product of the arrogant headphones. It belongs to the yellow color of Jabra theme, it is in the package positive and negative, and up and down as a decorative color.

Behind the product packaging, we are able to learn more about the Proceedings headset. Up to 15 hours of battery life with the battery box, noise reduction technology using up to 4 microphones, and the claimed 'reliable and stable true wireless Bluetooth connection' For consumers, it is full of attractiveness.

Take away the paper sleeve outside the package, and open the drawer type package, we can directly see the series of accessories that Jabra and Jabra bundled with them. The charging box also has the function of storing and supplementing life for the real wireless headphones. , Indispensable. In addition, in the bottom of the small box, is also equipped with two different specifications of the silicone sleeve, used for charging micro-USB cable, and related instruments, basically able to meet daily use.

Previously there were friends who were concerned about PConline's real wireless headset evaluation. Maybe they will remember Jabra's enthusiastic product. From the design style, the law is still adhering to the enthusiastic style. The panel also uses a round design. But Due to the need to accommodate the function in the design, there are some differences between the two. Unlike the aggressive use of the ear wing design, as a fulcrum to maintain stability when wearing, the law has a small tooth in the front of the cavity , Through the design to withstand the ear, with the inner cavity along the ear design, so as to ensure the stability of wear.

At the same time, it is this small tooth. We can see three rows of openings on the top. This is the key to the convenience of the built-in microphone, picking up the ambient noise, and thus improving call quality.

As a very important accessory of the real wireless headset in use, the size and surface material of the battery box are also considered by consumers. From the comparison of the above figure with a hairy coin, we can see that the size of the storage box of the cartridge can basically be Easy to put in the inner pocket of the jacket, it will not be troublesome to carry. The surface of ABS shell is sprayed with skin-like coating, which makes you feel warm and comfortable. At the same time, it is inevitable that these materials are not very wearable. .

However, in terms of user experience, the battery box is slightly deficient. The earphones, after being placed in the storage box, are not as absorbent as the AirPods, which conveys the sense of “income earned” to the consumer. It's not too stable, so you have to pay more attention to it when you store it.

Experience and Subjective Sense: Nice, but still not able to fly

First of all, let's take a look at the connection. Both hands press and hold the keys on both sides of the keyboard at the same time. At the same time, the pairing between the ears is completed at the same time. The rules will prompt the user to open the Bluetooth list of the device for searching and matching. The whole process of speed experience is quite friendly, there are few cases of signal abnormality during the entire experience, and the signal delay is basically negligible when watching the video. There is no need to worry about subtitles and people's lips can't match. In one sentence, because the earphone is an in-ear structure, and the control buttons are all on the front, each operation will have the feeling of slamming the earphone into the ear, which leads to the basic function buttons on the melody.

In addition, a little bit of regret, the law still can only be uttered unilaterally (on the right) when talking, and it is different from AirPods' bilateral voice. This is no longer a problem with the Bluetooth 5.0 norm of blessing - used by AirPods. The W1 chip, in addition to the built-in Bluetooth decoding chip, also has a wifi chip at the same time. It is the addition of this wifi chip that allows the AirPods to use two Bluetooth channels to complete the synchronization, thus realizing the binaural call effect.

However, even with a single-sided call, the built-in four-phone microphone is still guaranteed in terms of call quality. The voice is loud and clear, and the lines of the voice are quite obvious. Even in daily action scenes (such as walking or being in the car) Inside), the call effect of the melody is still guaranteed. With four microphones plus Bluetooth 5.0, the call quality is guaranteed.

What about the sound performance of the rhythm? In order to fully understand the sound performance of the rhythm, the evaluation selected the iPhone 8Plus supporting the Bluetooth specification 5.0, the Sony 'black brick' NWZ-1A supporting the LDAC, and the domestic popular Mobile phone, for a comprehensive evaluation.

First of all, let's talk about a lot of friends are concerned about, due to the impact of different format support to bring the sound quality. First of all, we open the LDAC priority mode, using black brick connection rules. As shown above, black brick reminds the law Connected in SBC format, so we can infer that the law is using CSR8760 chip, support 16bit music.

After clarifying the answer to this question, let's take a look at the sensation of hearing. Compared with AirPods, due to the firmness of the wearer, the seal can be better sealed. Under the influence of sealing, The bass of the law, whether it is thickness, density, or dive, has delivered a good performance. Clear and moderate, flexible low frequency, can express a better sense of atmosphere when performing music, used to exercise for yourself It's a good choice to cheer on.

But in fact, the low volume of the rhythm is not too much, so its midrange performance is not affected. The rhythm of the midrange is a relatively solid balance. A slight modification makes the sound warmer. Listening to male and female voices with a rhythm feels quite good. The vocal distance will not be too scratching. In contrast, the more sturdy boys will perform better. When listening for a long time, the vocal experience of the deduction will still be more tolerable, and there will be no obvious fatigue. sense.

In the high frequency performance, the interpretation of the law will not be too bright. The suitable brightness plus good extension force can have enough liveliness when expressing the string music. Plus the blessing under the Bluetooth 5.0 specification, 臻The distortion control of the law is better than that of the earphones that were previously using the Bluetooth 4.0 specification, so the entire high frequency performance is transparent and comfortable. Together with the loose, similar to the common jazz bar sound field, in most users Both tend to listen to the general trend of the studio's pop music album. The sense of separation and reflexivity of the rhythm sound is enough to use.

Finally, let's compare the differences in the perception of hearing in the common SBC mode and AAC mode - because Jabra's official website does not explicitly indicate whether the law supports aptX mode, and the SBC mode is more common in daily use environments. Assuring no bottlenecks in the evaluation, we chose 'black brick' and iPhone 8Plus as SBC sources and AAC sources, respectively.

Comparing the two, we can see that AAC compared to SBC can provide more moist and delicate sound and better interpret the taste of music elements. Contrast before Huang Huang listened to the differences in the quality of aptX equipment, AAC under the law The low frequencies will be more full and warm, providing a smooth musical atmosphere. In terms of hard quality, AAC can indeed provide better separation and line feeling, and the distortion will be smaller. In general, it is more recommended to match. iPhone 8Plus These Bluetooth 5.0 and AAC-capable devices do not support APT-X or higher specifications. The majority of other devices are transmitted in SBC mode, which is a waste of their own sound.

Summary: From which we can also develop a Bluetooth 5.0 headset development trend

As perhaps the first distribution, a true wireless headset that supports the Bluetooth specification 5.0, regardless of whether it is from the design or use experience, has delivered an answer that meets expectations. But in the current period we don’t just want to simply To talk about this product, according to my experience with Lao Huang, with the widespread popularity of Bluetooth 5.0, the current focus on the market's hottest (collar) Bluetooth headset and real wireless headset is bound to usher in a wave of climax , More stable, lower latency and higher signal bandwidth, will inevitably make more people willing to accept them.

At the same time, Lao Huang also hopes that the next Bluetooth 5.0 headset will be able to adapt to more transmission protocols, such as LDAC, APTX HD, and even Huawei's just announced HWA. These high-profile protocol standards not only To enhance the sound quality and signal of the headset, more extensive protocol support means more devices that can adapt. Of course, this is the place where Jabra's law should be improved.
