Because there are many business trips, I always wanted a noise-reducing earphone. After observing BoseQuietComfort25 for a while, I was preparing to start. Danish manufacturer Bang & Olufsen launched its first noise-reduction wireless headset BeoplayH8 at CES2015 Consumer Electronics Show (hereinafter referred to as H8), I am determined to get one when I see the news report. First, because most of the noise canceling headphones are wired, and BeoplayH8 can transmit audio through Bluetooth, it will be much more convenient. Second, B&O products in terms of appearance. Design aesthetics and brand height must win.
The BeoplayH8 on display at CES2015 has two colors, GrayHazel and Argillapight, which are actually two colors of gold shell + light brown leather, black shell + dark brown leather. On the more literary and outspoken, black is relatively common, so I chose the color of Argillapight.
Meiya placed $499, and then the American colleagues shipped the meat back to save a freight, BeoplayH8 listing price seems a little expensive, but it feels quite good when it comes to hand, after all, is supporting aptX technology Bluetooth wireless noise canceling headphones, and There is also the brand aura of Bang & Olufsen.
After receiving this BeoplayH8, I also called the B&O store in Hangzhou. The BeowicH8 of the Bank of China is said to be listed recently, but the sales customer did not inform the Bank of China.
The side of the package is printed on the side view of the earphone. The design is simple and elegant. Users who are familiar with B&O products should find that the appearance of BeoplayH8 and BeoplayH6 wired earphones is the same. H8 can be regarded as an upgraded version of H6 headphones.
The back of the package is printed with H8 headphone function and control introduction, mainly in English. This headset not only has two highlights of Bluetooth wireless transmission and noise reduction, but also a touch-operated earphone, which will be described in detail below.
Pseudo-opening the box, this BeoplayH8 was opened and auditioned by colleagues in the United States. The first thing to open the box is the feeling of being surprised. The gold of the H8 earphone is not the tacky "golden color", but the lighter gold. It looks a lot more noble than the average gold.
The metal shell of the cavity is made of aluminum alloy. The surface of the anodized aluminum is very exquisite and the texture is very good. The surface of the shell is very delicate and the concentric circle drawing texture. The camera's macro ability shooting is limited, but it can not be expressed.
There is a small logo on the right side of the cavity shell. This shell is the touchpad. Before it was disassembled, it was attached with a transparent protective film. The logo was printed on it and lost. The upper and lower positions are ANCON/ ANCOFF, the left and right position is the track selection, the touch feedback is more sensitive, there will be a light "drop" sound, of course, the touch operation can only be used when Bluetooth connection is currently available.
The head beam and the unit cavity hanger are also metal, the surface is matte texture, and the immunity is not the gray part of the touchpad. The outer casing is made of plastic. It seems that the plastic taste is a bit heavy. This part is because the circuit is to be placed. Plates or batteries, plastics are easier to mold, this is understandable, but the plating on the outer casing or metal texture should be more coordinated.
The accessories in the package are all packed in small black boxes.
There are not many accessories, except for paper manuals, warranty sheets, etc. One wire is MicroUSB charging cable, 3.5mm earphone pair recording cable, and another air plug is provided. The storage bag is a velvet bag. The attachment configuration of BeoplayH8 is basically Same as H6.
For B&O's velvet bag in headphones, many users of H6 headphones have said that it is too cold. B&O officials have talked about this when they released BeoplayH6. Some users will use the headset on the plane. If you use a hard storage box, you may not be able to put it in the bag on the back of the seat. If you use a soft cloth bag, you won't have this problem. B&O also has a leather earphone bag HeadphoneLeatherBag, which can perfectly fit the H6 or H8 headphones, need to be purchased separately.
Aviation plugs and wires, work looks more common.
There is a small buckle on the right side of the casing. After opening, you can take out the rechargeable battery with a capacity of 700mah. The official data is in the battery life: 14 hours (active noise reduction and Bluetooth), 16 hours (Bluetooth only), 35 hours (active only) Noise reduction).
Bluetooth switch and indicator light.
Charging interface and 3.5mm interface, you can still use the headphones through the wire without electricity, but there is no noise reduction function.
The head beam is relatively hard leather, and the inner layer of the head curtain is sponge plus fabric.
The earmuffs are New Zealand lambskin, soft and comfortable, and have a memory effect. With a long time, the leather will deform and shrink along the shape of your ear. The longer you use it, the more you will feel the earmuffs fit. Your ears. The logo of the left and right channels is printed very well inside.
The telescopic joint is also aluminum metal, very strong, you can see the headphone cable hidden inside.
After adding Bluetooth, noise reduction circuit and battery, the weight of the H8 is only 255 grams. It is still light in the head-mounted noise-reducing earphones. The leather of the earmuffs is also very good. It will not be tired for a long time. .
In addition to feeling that the plastic part of the outer casing is somewhat contradictory, the work of BeoplayH8 is still very good. The design of the whole earphone is also very simple and beautiful. The more you look, the more refreshing the taste.
It’s great to have Bluetooth wireless in the headset, especially when using a laptop or tablet, there is no line constraint, there will be no annoying lines to go, it will feel more convenient.
BeoplayH8 uses the Bluetooth 4.0 standard and supports aptX audio encoding. A big problem in the early Bluetooth headset sound quality is the delay and bandwidth of the transmission. The overall steps of the Bluetooth headset transmission process are like this. Take the Mp3 file. It will undergo two decoding and one encoding process (Mp3→pCM→AAC/SBC/apt-X→pCM). Since Mp3 itself is lossy compression, after a lossy coding, the effect on sound quality is not mentioned. Yu, and even if it is lossless coding, it will experience a lossy coding in the whole transmission process, which completely loses the meaning of losslessness.
aptX audio encoding is not really lossless. It is a hybrid encoding, but it can be close to lossless. This encoding can support high resolution audio up to 24bit/96kHz. If Bluetooth transmission actually uses this kind of encoding, it can be achieved. Without the same effect, there are more and more mobile phones and front-end audio devices that support aptX.
However, in actual use, there are obvious differences in the sound quality between the BeoplayH8 Bluetooth connection and the 3.5mm audio connection. When the noise reduction function is turned on, the sound will be adversely affected.
According to the results of the audition, the best working order of BeoplayH8 sound quality is:
3.5mm connection (noise reduction off) → 3.5mm connection (noise reduction on) → Bluetooth connection (noise reduction off) → Bluetooth connection (noise reduction on).
First of all, the effect of noise on the sound after the noise is turned on.
In the 3.5mm wired connection mode, no music is played. Turning on the noise reduction will hear some slight "Ziz" noise like most noise-cancelling headphones. It sounds a bit like the front-end noise, and the noise reduction effect is good. In the air-conditioned room and the road, a simple trial, the isolation of external noise is still relatively powerful, after the start of playing music, the noise caused by the noise reduction function is not obvious. But the noise reduction seems to the overall sound The sense of transparency has caused some influence. After the noise reduction is turned on, the sound permeability is reduced, which is a common problem in noise canceling headphones.
The sound in Bluetooth mode is not 3.5mm wired connection, especially in Bluetooth mode, the noise reduction effect is more obvious. The overall sound transparency, the potential of the bass, and the wide sense of the sound field are obviously less than 3.5. Mm wired connection. This is because the principle of active noise reduction is to create noise to offset the noise generated by the environment. Therefore, the general noise-reducing headphones have a relatively good sense of hearing. From this perspective, H8 is doing a good job.
However, the noise reduction function is only used in certain environments, such as airplanes, subways, and other functions that need to be turned on in a noisy environment. Turning on noise reduction in noisy environments can make people hear the sound clearly. Without being affected by environmental noise, it is possible to obtain a quieter listening environment. It is not necessary to use active noise reduction in a quiet indoor environment. The sound insulation effect of the H8 itself is not bad.
Finally, let's talk about the original sound characteristics of BeoplayH8, use 3.5mm wired connection to turn off noise reduction.
BeoplayH8 uses 40mm speaker unit, 20-22Khz, the parameters are basically the same as H6, are very good driving headphones, with iphone/ipad or other Android phones, tablets can drive a good sound, so Don't worry too much about bad push.
BeoplayH8's bass is much more, obviously more than the average 40mm unit headphones, B&O's many headphones and speakers have this feature, small and strong bass. H8 bass elasticity is very obvious, and very Strong feeling, but the dive and overtones are a little less, unlike some big headphones, those long and thick styles, to be slightly shorter, seems to intentionally control the cohesion of the bass, to highlight the power of the bass, in the bass sound comparison The rhythm of BeoplayH8 is very good in many tracks, it is very suitable for interpretation of this track;
The medium frequency is sufficient for density, and the middle and high notes are softer. I think the treble is brighter and better, but this relatively soft and sweet tuning seems to be more suitable for listening to music while resting.
The lateral sound field of the sound field is still quite wide. The separation of the left and right channels is relatively high, and the depth direction is slightly narrower. In the phase of the sound, the vocals of the BeoplayH8 high frequency band are relatively close. In general, the sound of the BeoplayH8 should be The tuning that most people would like, the sound of a good bass and the soft, slightly warmth of the voice, the vocal has a sweet feeling, B&O this headphone tuning is a relatively conservative and conservative style, but it has always been Emphasizing the sound characteristics of the sound field and the sense of space, the atmosphere is very good.
This BeoplayH8 is quite satisfactory after it starts. The wireless, noise reduction and touch functions are still very powerful. Needless to say on the appearance, B&O's product design has always been very unique to the control of metal and leather. Have an elegant temperament, with the local gold golden iphone is also good; listening to the sound as a pop music headset is also very good, personal feeling tuning is more unrestrained than H6, the current BeoplayH8 has been promoted to my preferred headset to carry, in addition to the above For three reasons, Bang & Olufsen's glittering brand aura is the most dazzling, which is actually the main reason why I bought this headset.
