Active Noise Cancelling Headphones often appear in a variety of "when it's good to meet it early" or "significantly improve the quality of life." And he also remembered for the first time in the Apple Store tried active noise reduction headphones brought about by the shock, but because after all, not just needed, the general price is not cheap, and at the time their focus on headphones is more about sound quality, so it has not been ; Afterwards also used some game or X.1 multimedia headset attached to the so-called noise reduction function, but the effect is not obvious.
Recently, because of moving, downstairs in the repair of subway exits, so you know, day and night noisy, plus often go home to work overtime, so start an active noise canceling headphones become a top priority. Just recently innovation also released the latest ANUVANA model ANC, mainly for active noise reduction, plus only a few hundred price (Tmall uses only about 760 after the shop activities), several times cheaper than QC, DS mentality I, considering the next, or the first to start ANC forget, after all, can also achieve -18dB (87%) noise reduction effect, and what the sound quality, I do not have any need.
Creative Creative Aurvana ANC Active Noise Cancelling Headphones Sun Single Headphone packaging design is still good, what the parameters of the function at a glance. 
Open inside is the storage box is also considered after business travel essentials. The design of the storage box is a flat setting, but what is interesting is probably the design of the inside accessory bag, which is similar to the setting of the demon felt. You can fix the position at will, but it is a pity that only one storage bag is included. If there is one more, you can put some on the way. Other attachments. 
The basics of all the accessories are these. What I didn't take is to attach a battery (which has already been installed), an aircraft connector, and a headphone cable. 
Headset MIC port, with the operation button, can answer, play and switch like, but no volume adjustment is a pity. 
Can be inserted and replaced, but in actual use, I often unplug, and then only use noise reduction. 
The chrome plated panel is still relatively beautiful in a clean state; the other end is a noise reduction function switch, and the other end is where the battery is installed. 
Although it is a 40mm unit, the size of the earcup itself is just the kind that covers the ear. 
The unit can also be rotated 90°, on the one hand, it can be stored on the one hand, and on the other hand, it can be adjusted to a more suitable angle. In addition, the ear beam part is also designed to be slightly special, so the wear itself will not press the ear, and the overall match is quite comfortable. of. 
The actual use of results, it is very exciting to open the packaging experience on the first day. The first feeling is that the workmanship design is quite good, the more typical business style, the details are not above the glitches and the like; the weight is relatively light, even after installing the AAA battery; wear is also considered acceptable, although it is a small ear Hood, but personally tried to use one afternoon.
What about noise reduction? A switch distinguishes between two worlds: I remember that it was used at 7.8 o'clock that night. At that time, it was at the peak of the off-duty hour. Therefore, I could still hear the car driving sound or horn sound, as well as the construction sound of the construction site, and turned on active noise reduction. After that, the environmental sounds have been significantly reduced, and only the relatively high-frequency sounds like horns are still heard (but also weakened to acceptable). It feels like the world in the ears has become vacuumed and the noises of the ears have been pumped out. separated. After turning off the active noise reduction function, the ambient sound is obviously increased. Although the headset itself has a certain passive noise reduction, the switch between the switches is quite obvious.
After that, the goods were brought to the company, which consisted of neck pillows and eye masks. In the office environment, the main function of the active noise reduction function is to reduce the ambient sound. Therefore, it is still possible to hear what others are talking about, but the voice after the withdrawal is still less annoying.
Most individuals use their time as "wireless headphones" for most of their use. They only turn on noise reduction because they are not used to listening to music or anything when they are working. However, they still watch videos and even games such as playing watch. First, they can say this. , Even if it is to listen to music, the best noise reduction function is best to open, opened the feeling of noise reduction headphones on the second room, the resolution of what have significantly improved; but after all, is a main function of noise reduction headphones, and style Also biased toward the morning, so the headset itself is not much tone, three-frequency relatively balanced, but slightly less than it, this style is relatively safe and resistant.
In addition, if there is any deficiency in the ANC, individuals may be more concerned about the "wireless", wireless and noise reduction are actually two ways to easily enhance the user experience, and the combination of the two believe that the noise reduction headphones Inevitably, if the ANC has a wireless version, the individual will feel more OK; in addition, the noise reduction mode is currently only "switching", and there is no noise reduction scheme for other different use scenarios.
