Bose® QuietComfort® 15 Acoustic Noise Cancelling® Headphones(Old Version)
Honestly, I think the new Bose headphones bring QC-2 to shame!
I have owned both the QC 2 and QC-3 headphones for a couple of years, and their predecessors before it. My home is in a rural area that over time become increasingly noisy with car traffic, have chain saws, weed whack, aviation, boats, etc., have been a big fan of noise-canceling headphones, which for me gives respite from all this sonic assault.
When I read the specs of the QC-15, I thought, if this is an improvement compared with the QC-2, I have to try them. This is despite the feeling embarrassed to blow another $ 300 for what I feared would be a trivial difference in quality.
I need not have worried. When I turned on the QC-15, it was so close to the world. The strong roaring sound emitted by the air filter running 15 feet away, almost inaudible, the low rumble of distant boat, plane and car disappeared. The background noise generated by the QC-15 is significantly quieter than the QC-2, and noise reduction as Bose advertises covers much more of the sound field. My QC-2 headset is not nearly so good job to stop the white noise from the air filter as QC-15, for example.
Regarding sound quality, the QC-15, to my ear, better response in the bass range, 25 to 35 Hz, and Les resonance in the 80-150 Hz. The base is generally harder, too. If you are accustomed to mild boominess of QC-2, as I was, it may take you a bit of listening to appreciate the difference. In the higher frequency ranges appears to QC-15 compared with the QC-2. My 64 years old ears cut arount 8 kHz, so I will defer to the judgments of younger listeners in this area.
All-in-all, I am very pleased with the improvements, which manifests itself in this new version of the Bose headphones and feel that even at $ 300, they are well worth it.
The only negative criticism I can do so far is that the headphones produce a fairly loud click when you insert them into the QC-2. This is not a big deal, I just make sure to throw the switch on before turning phones on my head.
By the way, many users of the Bose (and other) noise canceling headphones complain, sometimes bitterly, about his feeling of "ear pressure" when the noise cancelletion is enabled. This is an illusion that occurs due to actual pressure on the offset UN eardrums (as when climbing or down in an airplane) has the effect of reducing the low frequency response eardrums. This loss of low frequency sensitivity is read by the brain as the pressure in the case of elevation, it is actually. Noise-canceling headphones dramatically reduce the surrounding low-frequency sounds, many of which we register unconsciously. The brain interprets this as pressure on the eardrum, but it's actually not the case. The feeling of pressure produced by the noise reduction is actually an indication of how very, very low-frequency background noise we tolerate under normal circumstances. Research shows that such low frequency sounds can actually be a source of low-grade anxiety. Therefore you will find that these headphones off of your nagging anxiety along with the background rumble generated by the rampant burning of fossil fuels, which are all around us.
Bose® QuietComfort® 3 Acoustic Noise Cancelling® Headphones
This is an update of a review I had left a while ago. . . I've had this headset for 3 years and used them for everything from commuting on a train for an 11 hour flight.
I had no doubt buy the QC3, to ensure that all prices would drive most people away. I also compared them with some other headphones I own: Shure E2C in-ear headphones, and Sennheiser HD280 Pro around the ear headphones I have for my stereo. Bose has been my primary travel and commuting headphones.
Sound Quality:
-The music from a stereo, the quality is very good, but the ear proper placement is key. I think because of the on-ear design, if not exactly something one becomes subdued treble and midrange. Once you know where your sweet spot is, it is not very important to adjust the position. The sound quality is very good at all frequencies, and gives surprisingly good bass. I think the sound is close to my Sennheiser which has a small nod to the accuracy and soundstage. For MP3/iTunes purchased music, I compared the QC3 with E2C and Bose get nod especially with the bass (which is difficult to get in the ears, but a perfect seal.)
Noise Reduction:
-It was great for noise reduction. I had compared them with previous QC2 (QC 15 predecessor) around the ear headphones at the Bose store. Surprisingly, I found the QC3 be better than QC2s, go figure. During the flight, I found QC3s really weakened planes and other background sounds pretty good. Be aware that there is a feeling of pressure, which can be uncomfortable for some, so best to try them before purchase. I thought it strange at first, but was fine with it on my flight. I watched three movies and listen to MP3 files and slept without any problem in just one flight.
Comfort:
-I must say that I think QC3s to be the most comfortable for me personally than any of my other headphones. The ear cushions are very comfortable. I usually wear glasses and around the ear design is not convenient for me with my glasses on for long periods and I can not get a good acoustic seal with my HD-280 with glasses (and I have no bulky frames). The QC3s was quite comfortable on a long flight.
Noise leakage:
-Minimum of the best from my point of view when in a quiet room. My wife has never complained when I use them while she tried to sleep.
Durability:
-Reasonable construction. They have survived placed in my portfolio, but often the case for the past three years. Not bulletproof, but if you take good care of electronics, this should not be a problem (I put them at long distances).
Battery life:
Claimed-life is 20 hours, and it is probably correct. I have not measured it recently, but the battery still holds a charge well after several years. I had not charged the battery on the round-trip flights to and from Rome to Chicago and listen some time before and after. Sorry, you're out of luck when the battery dies. . . pack the charger or an extra battery (too expensive of course!).
Price:
Bose charging relatively high prices for their products. Given any outstanding options out there that Audio Technica AC7s, it's really amazing Bose has not lowered the price on these.
Bottom row:
-For me, the contract manufacturer was pleasant to the ear design with great sound quality, no dangling external power, and excellent noise reduction.
iTouchless Pure-Ear Active Noise Canceling Acoustic Headphones
Two features drove me to buy this headset: 1) compatibility with the iPhone, 2) noise reduction feature.
I was very excited to try it. After my first use I was disappointed to discover that it did not work with my iPhone if I jiggled the cable, holding it in place. This failure was surprising and somewhat misleading, since it obviously is alleged that the manager works with the iPhone. Otherwise I would not have bought it.
The noise canceling feature works as promised, for ambient sound, which was fantastic when I got some music that flows into the headset (on my laptop). The quality of the sound is crisp. On the other hand, if you're looking for a set that will stop / reduce audible noise (like me), this may not be the product you are looking for. I'm still deciding whether to retain them. Given the price I paid, it seems like I would get exactly what I wanted.
Eliminates up to 18 dB of ambient noise at 200 Hz.
40mm Neodymium magnet drivers deliver deeper bass and clear sound quality
Compatible with home and in-flight entertainment and the new iPhone.
Soft ear pads for extensive comfort
Working with one AAA battery for up to 70 hours of use
Bose® QuietComfort® 15 Acoustic Noise Cancelling® Headphones NEWEST MODEL
I purchased the Bose QuietComfort Noise Cancelling Headphones 15 about a month ago and I am thoroughly impressed thus far.
Sound Quality: Strange as it may sound, I feel that I have ever listened to any of my songs! This headset completely modernize every song. You will hear things in some of your favorite songs you have not heard before. As it says in the title, this is an acoustic headset so do not expect loud and powerful bass. If you like lots of bass, this is not the headset for you.
Noise Reduction: I think I can still hear people talking when I'm on a plane, but most of the background noise disappears. I will describe sounds like you are under water or by putting your ear to give you an idea of the sound. When you play some light music in the background all the people talking tends to disappear. I'm picking up anywhere from 50 to 100 flights a year, and now that I own a Bose headset, I could not imagine not having it with me.
Comfort: The headset is extremely comfortable with the leather around the ear and leather on the top of the headset. This makes it very comfortable for long periods. I used to use ear plugs and found that my ears began to hurt after 30 minutes. The only thing I will mention is that your ears get a little hot a sweaty after a while, so it's good to give them a breath of fresh air every hour or so.
Case: This box comes with a carrying case to protect your Bose headset. It was a big selling feature for me because every trip I make, I was worried about destroying my headset. This allows me to put the case in my bag and not have to worry that I crush it. Good complement Bose!
Cord: Even though this headset is not wireless, it has a detachable cord that I find very useful. If you do not want to hear something, do not attach the cable, you can relax with noise reduction function. To listen to music or a movie, though the cord. Simple.
Batteries: The headset runs on (1) AAA battery that fits right into a nice position on the headset. I keep an extra AAA battery in my bag just in case it dies when I am traveling. I have not had to change the battery yet, and I have used it for quite a few flights. I am very impressed with how long it lasts!
Aircraft contact: Bose also included a flat wall, as some airlines are still using. I have not come all at once, I have had to use it, but it's really nice to have if I need it.
Ned's: There is not much I would change if Bose QC 15, but the important thing would be that I can not listen to music on my battery is dead. Again, this has not happened to me, but if my battery was dying, I can not listen to music. You must have noise reduction function for listening to something. Apart from this, there is nothing I would change.
Price: This headset is quite expensive, so it was not designed for the average person. There are other headsets that I would recommend. But if you're the type of person who travels a lot to end up in places where the noise bothers you (ie trains, buses, etc.), this headset for you.
Well done Bose, you have turned the heart of a believer and I could not imagine traveling without my Quiet Comfort 15!
Bose QuietComfort 2 Acoustic Noise Cancelling Headphones
After reading some of the other reviews, I feel I must weigh in with my opinion about these headphones. I bought them online from Bose after some research of similar products. I'm not made of money, but $ 300 did not seem bad, because I really enjoy listening to music, and I own some incredible Klipsch speakers. I think the most important component in an audio system is the final step, the sound sensor, whether they are speakers or headphones, so I tend not to skimp on either.
That said, I've listened to a wide range of headphones, and I own a pair of Sony V600 is. The sound quality on the Bose QC2's are on par with the best I've heard. I personally do not get the feeling of "pressure" mentioned by others, but the noise canceling feature works produce a sense, frankly, you do not get anywhere else. It's not annoying to me whatsoever and I do not even notice it after the first minute of listening. As a reference, I work in a noisy production environment, and I wear foam earplugs in my ears more than 8 hours a day, then the QC2 is completely unobtrusive to me.
As a tribute to their noise-canceling feature, I wear them when I turn off my lawn with my cheap (high) riding mower, and as such they are nothing less than phenomenal. I put them in my Muvo MP3 player and turn up the volume on your player up to about half to three quarters, and I have not even noticed the mower engine anymore. No other headphones I've tried could not let me listen to music while I mowed.
The AAA battery seems to last forever. The construction of QC2's can best be described as very high quality but light. The "phone weighs very little, but I will not let them out of a table for fear of them breaking. I tend to be very careful with my electronic" toys "but I still find myself treating them more carefully than usual.
The bottom line is that I am quite happy with my QC2's. They did not cancel all sound completely, but they decrease sharply lower cancellation rates (road rumble, footsteps on stairs and floors) better than higher frequencies (female voice, television sound.) When I bought them, it was Bose running an offer on a free CD player with the purchase of handsets, and it helped push me over the fence. Even without the free player, I recommend buying them without reservation.
