Description
What are the Bose QuietComfort 45 Headphones?Bose QuietComfort 45 Headphones is the successor to QuietComfort 35 Series II. They deliver high-fidelity audio performance and world-class noise cancellation that allow users to hear more of their music and movies - while traveling, at the office or at home. QuietComfort 45 delivers a new Aware Mode, improved battery life now up to 24 hours, and an updated design. Bose QuietComfort 45 Headphones?QuietComfort 45 Headphones offer the same unmatched combination of audio performance, while delivering improvements in key areas such as ANR performance, voice pick up, and up to 24 hours of battery life. In addition to the performance improvements, QuietComfort 45 introduces a new Aware mode, a noise rejection array for clear calls in noisy environments, and connects with the Bose Music App. Product TechnologyWhat is Acoustic Noise Cancelling headphone technology?Acoustic Noise Cancelling headphone technology is a method of reducing unwanted noise by electronically creating a signal that is the mirror image of the unwanted noise. Microphones in the earcups monitor sound at the user's ear and externally. The monitored sound (music and noise) is compared to the sound the user wants to hear (the signal coming from the audio input - this could be music or silence). The difference between the monitored sound (from the earcup's microphone) and the sound the user wants to hear (music or silence) is noise. The electronics in Bose QuietComfort 45 Headphones instantly process the noise signal, and a precise equal and opposite signal (correction signal) is created. This opposite signal is then sent to the speaker in the earcup along with the sound the user wants to hear (again, this could be music or silence). The result is three signals being presented to the user's ear: noise from the environment, the sound the user wants to hear, and the correction signal from the electronics. The noise and the correction signal nearly cancel each other, providing a clean, high-fidelity sound signal at the ear. What is TriPort acoustic headphone structure?Proprietary TriPort acoustic headphone structure utilizes external ports to vent the earcups and effectively enlarge the acoustic volume, without increasing the size of the earcup. The result is better audio and active noise reduction from a smaller, lighter, more comfortable headphone. TriPort acoustic headphone structure is used in all our consumer headphones and headsets. How is the total noise cancellation in Bose QuietComfort 45 Headphones achieved?Bose QuietComfort 45 Headphones utilize both active and passive noise reduction technologies. They use a sophisticated proprietary electronics approach for active noise reduction, placing microphones both inside and outside the earcups. The electronics system senses the sound in almost any environment and then measures, compares, and reacts - instant by instant - to produce an opposing cancellation signal. Meanwhile, passive noise reduction is achieved by the combination of earcup fit, design, and clamping force of the headband. What is Aware Mode?Aware Mode turns on the external microphones of the QuietComfort 45 Headphones and feeds ambient sounds into the headphones, enabling awareness of the sounds in the environment, such as cars and emergency vehicles, while still enjoying audio content. When there is no music playing, the effect is that it feels like you're not wearing headphones at all. What is Active EQ?Active EQ (equalization) involves electronically tuning the frequency response to closely match the proprietary Bose response curve for headphone audio. The closer the frequency response comes to matching the target curve, the more lifelike the audio performance. What is full-spectrum noise reduction?Think of a piano keyboard as the full spectrum of human hearing, from the low notes at one end, to the mid-range notes in the middle, to the high notes at the opposite end. Through a combination of advanced active electronics and passive attenuation, Bose QuietComfort 45 Headphones reduce noise across the full range of human hearing (all the keys on the keyboard). Other noise reduction headphones may be effective at only some frequencies (only some of the keys on the full keyboard).What is electronic noise floor?Noise floor is the electronic hiss that may be heard with some noise reduction headphones. This noise can be annoying and can take away from listening enjoyment. Bose QuietComfort 45 Headphones use sophisticated electronic circuitry to minimize noise floor and make it virtually undetectable. This is especially important when using the headphones in transparency mode, where you're feeding sounds of the outside world into the driver signal. Noise in the system can be ampflied, impacting the naturalness of how you hear the outside world. What is Bluetooth technology?Bluetooth technology is a wireless standard used in mobile devices to wirelessly connect them to headphones. This
