Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Bose QuietComfort 25 Acoustic Noise Cancelling headphones. FREQUENTLY ASKED QUESTIONS PRODUCT TECHNOLOGY What 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.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones 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 of our consumer headphones and headsets.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Why do QuietComfort 25 Acoustic Noise Cancelling headphones use digital technology? We make conscious decisions about which technology is used in each of our products. In order to create a small-sized, around-ear Acoustic Noise Cancelling headphone with Bose noise reduction, we used an advanced digital electronic chip. It allows the circuit board to be much smaller, because we are able to use fewer electronic components than before.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones What type of sound quality do the QuietComfort 25 Acoustic Noise Cancelling headphones provide? Active EQ, TriPort® acoustic headphone structure, and a low noise floor enable QuietComfort 25 headphones to achieve high standards in headphone audio performance. Active EQ enhances the clarity throughout the entire spectrum of sound for lifelike audio reproduction.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Why are the QuietComfort 25 Acoustic Noise Cancelling headphones more expensive than other headphones? One of the reasons Bose Corporation has been successful is because our founder, Dr. Amar Bose, established a company that is committed to producing nothing but the very best products. When comparing prices, you must compare performance.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones What is the purpose of the extra adapter? The dual plug adapter is for use on aircraft that are outfitted with a dual audio jack. (Without this adapter, the user will hear the music or movie audio in only one earcup.) The adapter is also an audio attenuator, which reduces the volume of the airline audio system’s output, allowing for greater volume control. The attenuating dual plug adapter has no effect on the amount of noise reduction.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones COMPATIBILITY With which Apple products are the QuietComfort 25 Acoustic Noise Cancelling headphones compatible? Made for: iPhone 5s, iPhone 5c, iPhone 5, iPhone 4s, iPhone 4, iPhone 3GS iPad Air, iPad mini with Retina display, iPad (3rd and 4th generation), iPad mini, iPad 2, iPad, iPod touch (2nd through 5th generation) iPod classic, iPod nano (4th through 7th generation), and iPod shuffle (3rd and 4th generation) What happens if I plu
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones How are the QuietComfort 25 Acoustic Noise Cancelling headphones different from the other headsets designed to be used with the iPod, iPhone or iPad? The QuietComfort 25 headphones offer significant noise reduction, Bose audio performance and a comfortable around-ear fit for a better overall listening experience.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Can the QuietComfort 25 Acoustic Noise Cancelling headphones be used with Wave® systems? The original Wave® products were designed without a headphone jack. For consumers who would like to do so, connecting headphones to original Wave® products requires the purchase of an additional RCA-tomini-stereo-jack accessory. This is available from Bose at 1-800-444-BOSE. (The material number is 029100.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Can the QuietComfort 25 Acoustic Noise Cancelling headphones be used overseas? Yes. Most intercontinental aircraft utilize an audio jack that is compatible with the standard headphone plug at the end of the cable. Others may use a different jack that can be accessed by using the dual adapter that is supplied with the headphones.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Can I use rechargeable batteries? Yes, with a reduced runtime. The difference in capacity and voltage of rechargeable AAA compared to alkaline batteries shortens the useful run time of the batteries by approximately 20%. The use of NiMH low-self discharge AAA size batteries is a good match for the QuietComfort 25 Acoustic Noise Cancelling headphones for customers who prefer to use rechargeable batteries.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Are the QuietComfort® 25 Acoustic Noise Cancelling® headphones subject to electromagnetic interference (EMI)? Certain wireless electrical devices, such as mobile phones and wireless computer networks, may cause some static interference with audio products. The interference depends on the specific device and the distance from the audio product.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Do the QuietComfort 25 Acoustic Noise Cancelling headphones reduce more noise than the original QuietComfort headphones? Yes. Earlier versions of QuietComfort headphones all provided essentially the same level of noise reduction. The QuietComfort 15 headphones improved active noise cancelling and passive attenuation for a significant improvement in the amount of noise reduction.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones PRODUCT SPECIFICATIONS What are the mechanical specifications of the cables and connector? Cable length: 5.5 ft./66 in./1.68m What are the noise reduction specifications? Is there an NRR rating? Bose Corporation does not provide a noise reduction rating (NRR) or attenuation specification for our QuietComfort headphones. Interface connector: Commercial mini-plug (3.
Bose® QuietComfort® 25 Acoustic Noise Cancelling® headphones Can you get a pressure sensation when trying on noise reduction headphones? Our QuietComfort® headphones, including QC®25 headphones, cannot create any “static” pressure in the earcups. We infrequently receive reports from people who believe they are feeling some such pressure.
