B & O BeoPlay H7 Review: Super flagship Bluetooth headset, high-frequency analysis more prominent!
In this circle of the author's audio product industry, few people go to buy their own headphones for their own listening. Compared to its own circle of friends, many tech media editors seem to have a special interest in B&O BeoPlay's products. For example, Wang Ziru or audio editors of IT portals are a lot of users of B&O BeoPlay H8. As the B&O's positioning in the flagship H8 headset has the advantages of wireless Bluetooth and noise reduction combination, it is also the reason for consumers and technology media industry love.
For the further reduction of the noise reduction function B&O BeoPlay H7 this wireless headset, but more than the flagship H8 more pursuit of sound quality full-size earmuff-style design, as for the sound quality and design details of this product, please read this article.
H7 on the packaging continued H6 and other classic product packaging style elements, the main silver and blue world cover packaging combined with a film feel shiny. Thanks to the exquisite rendering of the rendered graphics and the delicateness of the typesetting texts, the H7 packaging is different from the exquisite style of the general domestic brands, and also fully experienced the simple and beautiful industrial design elements of the B&O brand. (Does China's many brands plagiarize B&O's packaging and I will say nothing about it?)
Behind the packaging is a detailed description of the product's construction, such as the innovative intuitive aluminum interface design, can be more demolition of batteries and one-button door design and other specifications of the leather material and specifications.
The side of the package is the basic CE certification of the product and related manufacturing dealer information. BeoPlay H7 is manufactured in China. From the APTX-CSR certification mark, H7 uses CSR's solution and supports APTX lossless coding support. In the APTX's official website, H7 technology licensing information can be found.
The front can see the ear cup shell body adopts the aluminum metal material to anodize the way to highlight the glossy shiny surface texture of the metal, the bottom layer is the gray plastic component assisted by the imitation skin texture rubber spray paint, while increasing the touch while transitioning the leather material The material color difference with the metal glossy surface is visual. From the design point of view, the combination of metal plastic and leather material achieves a very concise and simple visual effect. In the product design, the technical details are simple and the line details are also fashionable. H7 is still created by famous Danish designer Jakob Wagner.
H7 continues H8's aluminum metal panel intuitive touch logic. This kind of design is actually not new in electronic products, but it is still very difficult to do sensitivity and anti-jamming. Although the aluminum touch panel has four scale points and the LOGO is embellished with the touch direction, it is actually blind when worn.
You can adjust the volume clockwise or counterclockwise on the surface of the aluminum metal panel, or swipe left or right to perform the previous or next song-cutting operation. The playback pause or call answering can be done simply by touching the point. Completed, (although there is an up-and-down scale, in fact, there is no operation definition for sliding down). The reason why the entire operation design logic has been interpreted by B&O as an intuitive control design is here.
On the right side of the H7, there is a three-stage power button and a bluetooth open button. When you bind, you only need to push the bluetooth logo to enter the detectable search bound state. At this time, you only need to open the phone and search for the bound H7 headset. The binding process, unlike the general Bluetooth products, requires a long press to enter the binding state. There is also a Micro Usb universal charging port next to it, and a 3.5mm cable input for use when no electricity is available.
On the other side of the H7 is an independent battery compartment design. The battery compartment switch is located on the side of the bottom of the earphone. It only needs to push the button in this position to open the battery compartment door.
After opening the battery compartment, you can see a separate packaged battery similar to the mobile phone. The lithium battery model PLB-103 has a capacity of 3.7V 770mAh. It is manufactured in Japan and is covered with a plastic casing. It is quite quality-featured and has passed the multinational safety certification. .
The B&O H7 measures 197 inches wide by 225 inches high by 40 inches in diameter and weighs around 280 grams. It's not that heavy in mainstream earbud headphones, and the head beam of the product is made of strong aluminum. design.
The H7 head beam and ear cup connectors still use the classic half moon type shaft design, using aluminum metal can effectively strengthen the stability of the product, half moon shaft to meet a certain degree of activity adjustment is also very easy to use the built-in slot The bit is routed to the inside of the headphone horn to reduce the problem of internal wire loss caused by the folded design.
The more interesting still is the head beam design of H7, adopting the entire aluminum metal head beam processing and the inner tank line is quite simple and solid. The head beam sliding grooved rod is covered with a plastic sliding shell and supplemented with a fabric to avoid the head sweat and lack of air permeability. The outer layer of the head beam is made of New Zealand leather suede leather fabric and it is quite fashionable. (This design is really a labor-intensive practice)
The cup cover of the earphone adopts the natural affinity design of lambskin, which is quite good for some people who are allergic to PU fabric. However, the H7 earmuff cover is fixed, so it can not be replaced flexibly. Considering its own durability and maintainability, it is not troublesome. Pay attention to wipe it with clean water to achieve daily maintenance and durability.
Headphone accessories comes with a charging cable and a 3.5mm headphone cable. In addition, a large velvet bag and associated standard instructions and warranty information are included.
In actual use, it takes only about one hour or more to fully charge the battery, so even using the original charging cable with a mobile power supply is quick and easy.
From the aspect of workmanship design, H7's process quality is still impeccable. In the design process, B&O still has a design value that is difficult to match with the same price. Even a lot of professional brand products are difficult to achieve. After all, B & O has always been difficult. The king of industrial design, which has been hailed as the audio industry, is not indefinite, especially the anodized earphone aluminum metal is quite exquisite and prominent under the refraction of the light source.
In terms of daily life, B&O H7 has advanced standby power control and energy-saving logic for CSR. The 15-minute non-player will automatically turn off the power to avoid wasting batteries. Therefore, although there are some complicated start-ups in actual use, the actual use of one power can be used intermittently for several days. If you do not want to waste the battery for everyday conversations, consider buying a 3.5 mm call line with a microphone. You can search for hands-free call lines on JD.com or Taobao to find these inexpensive, easy-to-use accessories.
Considering evaluating a Bluetooth headset, the author was still very cautious in comprehensive testing from desktop audio players, mobile players and mobile phones to achieve a comprehensive accuracy evaluation of the tri-band quality of the headset itself.
In the mainstream, there are few players that support the lossless design of APTX. I will use AK240 as a reference for APTX reference and cable players. In addition, Kayin’s latest I5 player and N6 and other classic players are used as wired input tests. Bluetooth and wired tests on mobile phones use VIVO's latest HIFI 3.0 architecture, vivo Xplay5 and typical IPHONE6S PLUS as front-end conditions.
The sound field performance of B&O H7 is biased toward the field restoration of near-medium distance, so it is more suitable for the appreciation of some small-sized music or movie categories. In the position of human voices and musical instruments, human voices may feel slightly prominent, and the high frequency space Height can also provide some sound field space support. Taking into account the range of low-frequency exploration is not deep, but in the sound image of the vertical sound field performance is also a good performance.
The overall sound field is well-suited for listening to all types of music, but it is only a bit too hard to perform large-scale or relatively wide recording types. This will not feel too much fussy for users who listen to music on a daily basis. Especially as a Bluetooth sound field performance is quite ideal.
Low frequency performance:
Although the H7's low-frequency trend is similar to H8 at first, the resolution and details of the sound should be better regardless of the Bluetooth or cable mode. H7's low-frequency trend is mainly to highlight the low-frequency sense, the low-frequency texture is slightly biased to have a certain sense of metal listening, the low frequency of popular musical instruments has a very good restore.
The low-frequency dive is not deep and has a relatively good transient response. The low-frequency layering transition has some slight adjustments on the transition. Therefore, the texture may lack a higher degree of naturalness and a solid transition, but listening for a long time Deliberately softened traces. This is why B&O doesn't do too tight low-frequency in the headset. Instead, it focuses on the relatively prominent amount, and the texture is a reasonable design that focuses on details.
The low frequency in the wired mode may not appear solid in the direct push of the mobile phone, the sound can feel the sound of the speaker is not sound enough, and the front-end insufficiency is solved under the Bluetooth wireless. Under the APTX or the SBC encoding, both the Android mobile phone and the Apple mobile phone can Listening to pop music in the texture of those strong low frequency, which is H7 is more emphasis on Bluetooth DSP tuning advantage. From the low-frequency style adjustment point of view, H7 is very suitable for popular and pure music and even three mainstream types of soundtrack.
H7 is also an ideal choice for business attendance or ordinary movie viewing. The air impact and metal tone of some big movie explosion scenes can be restored just right, and you need to connect Bluetooth via your mobile phone to get satisfactory results. It can be seen that B&O is The low-frequency part that is difficult to achieve on Bluetooth transmission has not compromised either.
IF performance:
H7's mid-range part has a certain situation of low-frequency lift involved, which causes some recordings to be biased towards low-frequency and lossy music with more vocal sounds. Listening to non-destructive music benefits from the APTX encoding support of Android phones in the vocal layering and resolution enhancement is very obvious, the details of the vocal level analysis has a quite obvious difference in hearing, especially in some domestic intermediate frequency Details of the nostalgic mouth water songs can be easily identified. The overall H7 IF is generally under the light popular or recording quality better track, the overall vocal is still quite clean, especially in the high-frequency transition is very good, the texture of the instrument is very flexible and pleasant mid-range.
In terms of vocal aspects, H7 is more comprehensive. It can express the slenderness of women and also restore the fullness of some male voices. Generally speaking, there may be some styles of partial female poisons in some people's listening. After all, since the early A8 style, B&O has been paying attention to people's statement of the net analysis, which is one of B&O's music concept traditions. Even the A&O luxury car or home audio B&O insists on the style fully.
H7 is very suitable for listening to some ethereal female voices and exquisite ACG tracks, and some of the original sound of the vocal choral background music is also quite imposing, male voice is relatively boring and hustle and hard part of the relatively inadequate, while the ability to control the heavy metal rock is relatively poor After all, the H7 is the appearance and sound style are so gentle and elegant headphones.
High frequency performance:
For each B&O product that needs to identify the authenticity of the cottage, the traditional high-frequency tuning trend is the most easily recognizable part, and it is also a part of the B&O brand style that is most likely to be loved. Although the H7 is slightly dull when connecting to a mobile phone when connected to a wired network, under the adjustment of the DSP through the Bluetooth connection, the sound will appear quite rich in high-frequency glossiness and metallic feeling. The long listening time is so high in texture. Frequently, it does not stimulate, because the relatively stimuli in the high-frequency domain have obvious transition modifications and reductions, which makes the H7 tolerance very good.
Listening to some violins every day will reveal that H7's high frequency has a texture and elastic replay. Even Japanese ACG electroacoustic classes can fully restore a good bright rhythm, and more messy dynamics can be firmly controlled in the transitional modification. Adjust it. This is also an adjustment of H7's DSP in combination with the acoustic structure and the unit diaphragm. High-frequency high-frequency transitions and extensions are not lost during playback as much as possible to ensure that the height of the sound space is fully expressed.
What makes many people happily is H7's interpretation of UHF micro details of some female voices. Even under Bluetooth mode, it can show quite satisfactory performance. Under such high-frequency quality, many tiny details of the atmosphere of cinema are restored. Pretty good. In mainstream mainstream musical instruments and classical music performances, H7 is better at controlling two styles than H8. In particular, H8 does not sound like H7 is so clear and delicate, after all, H8 interfered with the perfect performance of high-frequency interference, the overall more popular.
Therefore, H7 is better than the H8 flagship in terms of high-frequency performance. Whether it is the resolution or the comprehensiveness of high-frequency texture, the H7 high-frequency style is very suitable for listening to those melodious triangle irons or pianos with a wide range. As a kind of musical instrument, the resolution of musical instruments in classical music is quite impressive with some small and medium-sized establishments.
In fact, the author has listened to the H6 H7 H8 for quite a long time. The only thing that made me satisfied is that only the H7 is represented by Bluetooth and wired input. Of course, the Bluetooth voice quality is more than enough to win the mainstream Bluetooth. First-line strength. Similar to the same type of product is only SONY or B&W and V-MODA's flagship wireless products, but B & O H7 still has a clear sound concept of B & O, focusing on clean sound style shows a good resolution lines and sense of hearing.
H7 only connected to the cable under the input IPHONE6S PLUS is still not satisfied with my feelings, Bluetooth cable under the H7 through the DSP to adjust the sound, use some Android phones have APTX support models, such as VIVO XPLAY5 and other domestic and foreign mainstream The flagship model will find that the H7 resolution is enough to hear the sound enhancement effect under lossy and lossless transmission. This is also a technical bottleneck for mainstream high-end Bluetooth headsets, which is quite elaborate for the acoustic structure and circuit adjustment of the headset.
The H7 positioning allows the flagship H8 to have a bit of awkward sound quality. After all, the H7 is an ideal full-face earphone design with an acoustic structure. For the ear-hugging H8 there are inherent advantages of acoustic conditions, especially from the design of the value and quality of the process to see H7 more cost-effective. Therefore, consider buying a bluetooth headset with a face value that is forbidden. In fact, H7's objective advantages of design and sound quality will become the preferred choice for most people. Although there is a certain benefit to the noise reduction function, it still depends on the needs of the environment. After all, the denoising of sound is also objective.
