On September 1, it was reported that Bose, a well-known brand in the field of noise reduction headphones, recently released its new generation of QC series headworn noise reduction headphones QC45.

Bose QC45 has little change in appearance design compared with the previous generation QC35 II, and the key layout is basically similar. The ear pad material is replaced by protein skin, which provides two colors: black and smoke white.

Bose QC45 has added Aware mode this time, which is the common ambient sound mode on noise reduction earphones today (QC35 II and Bose 700 do not have this function). The noise reduction level has also been further improved, but it does not have 11 level noise reduction adjustment on Bose 700; It is equipped with four microphones to enhance the ability to pick up voice during conversation; The headset adopts Bluetooth 5.1 protocol and supports the connection of two devices at the same time. In addition, it also retains the function of wired connection (audio cable is included).

In terms of endurance, the Bose QC45 can be used for 24 hours when it is opened under the nominal full power state, which is improved compared with the previous generation's 20 hours. At the same time, its charging interface is also changed to USB-C like the Bose 700. It takes 2.5 hours to fully charge, and it can support about 2.5 hours of playback after 15 minutes of charging.

At present, the overseas price of Bose QC45 is 329 dollars (about 2126 yuan), and it should also be launched in China in the future.
