Appeared from Bose for a long time "QC45"! Haste review

Bose's new noise canceling (NC) function wireless headphone "QuietComfort 45" (White Smoke)

New headphones after a long absence in the inscription series "QuietComfort"

The QuietComfort series released by Bose in the early 2000s has evolved for more than 20 years.The powerful sound, stable silencing effect, and comfortable operability and wearing feel are loved by many users, and now one of the most widely used headphones with noise canceling (NC) functions.

The wireless headphones of the series have been since "QuietComfort 35 II" (QC35 II) released in the fall of 2017.In Japan, the QUIETCOMFORT 45 (QC45) will appear after a long absence, with the "Bose Cancelling Headphones 700" (NCH700) released in the summer of 2019.Bose's current product with the name of QuietComfort also includes a complete wireless earphone "QuietComfort Earbuds" (QC Earbuds).

Where did QC45 change? Compare with QC35 II

The appearance of QC45 has not changed significantly from QC35 II.Two colors of matte -finished black and white smoke.When I checked the details, the position of the microphone changed a little.The dough inside the headband is a velor tone and smooth synthetic leather.It is a bit disappointing that the brand logo on the side of the ear cup has changed from a three -dimensional relief to a print.The one -touch pairing function by NFC has also been omitted.

QC45 supports battery charging with USB-C cable (QC35 II is MicroUSB).It also supports speed charge that can be used for about 3 hours in a row for 15 minutes charging.

The dedicated mobile apps used for pairing with smartphones and setting the main unit have changed from the conventional "Bose Connect" to the "Bose Music" common to new bose products such as NCH700 and QC Earbuds.

Listen to Noi Can effects & sounds

I connected the QC45 to Google Pixel 5a (5g) and went to the city to check my skills.

When the NC function is turned on, the BGM of the cafe, the voice of the person who speaks next to it, and the driving sound of the train disappear.When you start content regeneration, the colorful and rich sounds of music and movies are dynamic on the silence of a white canvas.

The conventional QC35 II was a specification that allows you to select the effect of NC from the app from two stages, high and low.Instead of the function of QC45, the external sound import function has been newly attached.You can select the NC mode "QUIET" or the outer sound import mode "AWARE" by pressing the button on the left side of the application screen or the ear cup.

If you choose AWARE, you will be able to hear naturally with the sound of the cafe BGM and the outdoor environmental sounds that play with headphones.I think the clarity of the outer sound capture is almost the same level as the NCH700.

The sound is impressive with a powerful and soft medium range.Tight and stable bass playback that does not swell too much enhances the tension of music.Compared to the QC35 II, it can be clear that QC45 has a higher clarity and spread of the sound field, and the localization of the sound image is more vivid.

The Bluetooth codec is up to SBC/AAC as the NCH700, but the sound that has been kneaded as a QuietComfort series is very complete, and there is no lack of sense of unity of music that leads to fine and smooth music.

The QC45 tends to draw more vocal contours such as vocals and pianos than QC35 II.The energy in the middle and high range is enriched, and there is a gorgeousness of the electric guitar cutting, the rhythm of drums snares and hi -hates.However, the power of the bass attack and the high resolution are better at the NCH700.

The NC effect of the NCH700 can be selected from 11 steps including the outer sound import mode on the application screen.I felt that when I set it for the maximum silence effect, I could get a quieter listening environment than QC45.

Inherits comfortable operability and high portability

The QC45 can operate the paired smartphone music playback and hands -free calls by the button on the side of the ear cup.The shape of the button is gentle and round, making it easier to press.

The calling of the paired smartphone voice assistant is performed with the multi -function button on the right ear cup.The buttons placed on the left are used to switch the Quiet/Aware mode and to operate the microphone for hands -free calls.The linking function with Google Assistant/Amazon Alexa equipped with QC35 II and NCH700 is omitted in QC45.

Some people who bring NC headphones into the plane and use the QC35 II, which can fold and fold the headband and ear cups, can be more compact than NCH700, so they like it.QC45 also inherits the foled double design of QC35 II.The case is very functional, with a cable for wired connection, a USB-C cable, and a conversion adapter for aircraft.

Easy to wear for glasses users.Stamina is sufficient

There is also a function to automatically turn off the power after a certain period of time without playing the sound.The waiting time can be adjusted at a certain interval between 5 minutes and 3 hours from the app.

The battery stamina has about 24 hours from the full charge.The battery capacity for 3 hours is secured by charging for 15 minutes, and it is fully charged in 2 hours.It is also worth noting that the maximum continuous playback time is longer than the QC35 II and NCH700 20 hours.If it is a wired connection, it can be continuously played for about 40 hours even in the NC -on state.

Since I am indispensable for everyday life, the headphones' ear pads that touch the temple (vine) of the glasses are soft, and the Bose QC series, which has less pressure, is useful.QC45 is also a headphone that is easy to wear for glasses users.Combined with the tough battery performance that supports for a long time, it is likely that the opportunity to use QC45 as a partner of the video conference will increase.

There is a price difference of about 7,000 yen between QC45 and NCH700 (NCH700 is around 46,750 yen).The NCH700 has a wealth of advanced functions that can be used as a high -level premium headphone, such as the intensity adjustment of the NC and the one -shot call for music playback using the Spotify application from the touch sensor.

It is possible to simply separate the QC45, where you can enjoy "Bose noise Canceling Headphones", and it is likely to be a headphone that will enhance each other.
