No distracting BOSE QC20i noise reduction headset experience

I first met BOSE or saw his multimedia speakers in the classmates. At that time, there was no concept. I didn’t know the brand when I knew it. At that time, I just thought that watching movies was particularly shocking, so for this brand from very early I had a good feeling. I came across a BOSE store when I was hanging around in Vientiane City, Shenzhen. I went to audition. At that time, I was poisoned. At that time, I should listen to Acoustimass@15. I am amazed at why BOSE can Such a small cavity in the interpretation of such a huge sound field, for the rendering of that atmosphere, I really want to take home. Instead, BOSE headphones, I did not have too much contact, before I took the opportunity to try IE2, there are companies Lost OE1, the impression is relatively low frequency, and BOSE noise reduction, has not tasted.

BOSE has always had great technical advantages in noise reduction. The previously launched QC15 is well received, but for BOSE, noise reduction is still a blank, and this time the BOSE QC20i is the first in the field of BOSE noise reduction. In the ear (in fact, there are two, there is one is QC20), the suffix has an i, compared to 20, 20i more than the headset microphone, you can wire the phone, you can also talk.

Get the QC20i, the first thing I saw was the design style of BOSE. The earphone itself used brown-gray, while the controller used black-gray, temperament, and business-oriented. The impressive shark on ie2 The fin rubber plug is also extended on the 20i, and this time it is an upgraded and optimized STAYHEAR+ shark fin silicone earplug. It is very comfortable to wear. Of course, it is still in the ear, plus the design for sound insulation, it’s still a long time. It will be a little tired. The wire is similar to that used by ie2. The texture of the black and white spiral is thicker. With the controller, the weight of the whole earphone is still some. It is difficult to tie the wire with the hand bag. sort out.

QC20i is the main noise reduction, which is also BOSE's master technology, a small in-ear headphones, built-in dual-microphone noise reduction system inside and outside. For long-term business travellers, it is an extremely useful function. Previous colleagues Just tell me the power of QC20i, I was suspicious at the time. The manufacturer computer listened to the first ear, did not open the controller switch (QC15 is not available when there is no battery, and QC20i is available), I feel the sound is boring, It seems to be covered with a layer of gray, weird, so it is not recommended to turn off noise reduction to listen to songs here. After opening, the whole sound is not the same instantly (the sense of hearing will be later), the whole portrait is isolated, only The sound of music is amazing. At first it will not adapt, especially before the music is turned on, the ear will be subjected to a kind of pressure, a little discomfort, and it will be better after adaptation.

The QC20i's controller is very small and exquisite. Unlike previous AA/AAA batteries, this time the controller has built-in lithium battery, so it is very light and small. There are two indicators, one is the power indicator, one is Mode indicator light.

Since it is a rechargeable battery, let's mention the battery life. The QC20i's battery life is up to 16 hours. From the time of my scattered time, 12 hours is no problem (protective hearing, ten hours) In fact, it is enough for many days), the charging time is nominally 2 hours, using the microUSB interface, the mobile power can also be charged, the battery is not a problem. When the battery power is less than three hours, the power indicator light starts to flash, and the charging will change. Yellow light.

Control is very good, QC20i design is very simple, in addition to control the phone's three buttons (volume plus, volume button, answer, three buttons), there is a button in the microphone position is to switch the noise reduction and Aware Mode mode buttons, and There is only one switch on the controller.

QC20i still inherits the style of BOSE, the tuning is very mature, undisputed is an excellent pop, rich American style. The low frequency is still the focus, BOSE QC20i's low frequency aspect is indeed some effort, first The ear feels that the low frequency is very comfortable. It is not the kind of very low-frequency, low-end, freely retractable, both rendering, but not arrogant. The dive and the amount are well controlled. Relatively speaking, the intermediate frequency and the high frequency are It’s expected to be a lot of ordinary, but it’s not bad, the high frequency is a bit sharp, and the medium frequency is relatively dull, but the analysis is really good, the sound is accurate and clean, with noise reduction, you can enjoy high quality at any time. sound.

Excellent resolution and noise reduction, allowing people to enjoy music at a comfortable volume anytime, anywhere. Due to the low frequency, the sound does not sound transparent, the guitar sounds not clear enough, but the ability to portray details is indeed commendable. On the subway, you can easily enjoy light music and turn on the noise reduction moment. It feels like the time of entering the bullet in the movie, and the surroundings are clean. The effect is really shocking. I don’t know what technology BOSE uses, after shielding the noise. The radio in the subway can still be heard, so that I lost the opportunity to sit in the station.

Take a few songs of different styles and say: "Anhe Bridge", Song Dongye's song, the beginning of the tambourine with the sound of the Chinese drum is very good, the effect in the QC20i is very good, the sound field is general (feeling should not), space Feeling is not strong, the voice is relatively convex, relatively close. Listening to the rap with the QC20i is good, the low frequency shock is not stunned, and the American tuning is really a natural pair. "Fly Love", the interpretation of the male voice is very Great, with excellent analysis, the sound of the big bass sounds, it feels good, it seems to be sitting in the band, and the big bass is standing behind you.

BOSE's own sound is good, with the black noise reduction technology, people can enjoy music "quietly" at any time, it really makes people love it. Compared with the headset, QC20i is not only light, but also more comfortable to wear. For users who spend a lot of time on subways, buses and even airplanes every day, BOSE 20i is a very good choice.
