Are you still bothered by the cumbersome job of merging multi-worksheet excel files into one worksheet? Another alternative is the happy medium—noise-reducing headphones, like our vPulse In-Ear Headphones, that still block a great amount of ambient noise. Then again, next time I’m on an airplane, I think I’ll be yearning for the noise-cancelling earphones all the same. I'm passionate about music, a lover of pop-culture, a runner with a mad sweet tooth and an addiction to coffee. Owner of vPulse and vFree and curious for the ventures of Velodyne Acoustics, I will be exploring our headphones and what we do next. Born and raised in Silicon Valley, I am a student at San Jose State University and Marketing intern at Velodyne Acoustics.
Bose QuietComfort 20 Acoustic Noise Cancelling headphones can block out the world… or not. Over the years, Bose has had their detractors, but they have also made some darn good products, such as the QuietComfort Noise Cancelling headphones and the SoundDock speakers.
I just purchased the Plane Quiet NC-7 Noise Cancelling Headphones from their US manufacturers Pro Travel Gear to wear while commuting to work on trains and buses. Proprietary noise cancelling algorithm providing up to 17 decibels of noise cancellation across the entire sound spectrum. 3.5mm Stereo plug and Dual-pin airline adapter (included) are compatible with all worldwide airline in-flight entertainment systems and portable electronic devices, such as laptops, iPod™ and other MP3 devices, DVDs and CD players.
Active noise-cancelling headphones can do everything that passive ones can do but they also add an extra level of noise reduction by actively erasing lower-frequency sound waves by creating their own sound waves to cancel out some of the the incoming noise.
Using a microphone, noise cancelling circuitry and speaker noise-cancelling headphones are able to provide a noise reduction of around 20 decibels. While noise cancelling headphones do a good job distinguishing between the audio a wearer wants to hear and the background noise he or she wants to keep out, some people say that they compromise sound quality by muffling sounds. Noise-cancelling headphones are better at eliminating low frequency sounds, such as the rumble of a train or roar of an air plane’s jet engines, than say the voice of someone talking on a mobile phone next to you.
The Plane Quiet NC7 Noise Cancelling Headphones can be purchased directly from Plane Quiet for US $80+shipping. If you prefer ear buds I would recommend the Solitude® Passive Noise Reduction In-the-Ear Stereo Headphones also sold by Plane Quiet for $US $39.95+shipping. I have actually already done that, and they are giving great service by shipping out spare parts. How about the sound quality of this headphone as compared with the other noise canceling headphones such as the Bose Quiet Comfort? Behind-the-neck designs won’t interfere with your hairstyle or your hat and will usually stay put during running or jogging. Less effective noise isolation than in-ear or full-size models, and less powerful bass compared with full-size headphones. Large headphones offer potential for maximum bass and loudness levels, and by fully enclosing your ears they effectively block outside noise. Large size is cumbersome for portable use and some full-size models can be uncomfortably hot, making your ears sweat.


I’ve used them now for about 12 months, but only on flights and ferries, otherwise I use my in-ear headphones (no need to take the bulkier ones when not necessary).
I have been using these headphones for a couple of years, but yesterday (November 27 2009) while sitting on the tarmac at Hong Kong with a 13 hour flight to London ahead of me, I was lifting them from around my neck onto my head and they just snapped.
I’ve had these for about 18 months now and have travelled over 200,000 miles using them.
There are three Best PDF to DWG Converter, AutoDWG PDF to DWG Converter, Any PDF to DWG Converter and Aide PDF to DWG Converter. The headphones contain microphones that capture the sound waves as they reach your ear, and then electric circuitry generates an “antinoise” signal.
They don’t require batteries, are lighter, and, of course, are much less expensive, while retaining very good quality sound. I’m the Summer Muse because I started writing here during the summer, I absolutely adore music, and I often lose myself in my musings. Admittedly, I would never describe myself as a hero of any kind and I tend to get seasick in open water. It's been awhile since I've reviewed a phone from HTC, so I was excited to see what their latest flagship device offered. That’s because the materials of the headphones themselves block out some sound waves, especially those at higher frequencies. That means about 70 percent of ambient noise is effectively blocked, making noise cancelling headphones ideal for airline and train travel, open office environments or any other location with a high level of background noise.
The dB scale is logarithmic, meaning that a change of 10 dB represents a tenfold change in loudness. That’s because higher frequencies are more difficult to cancel out, so the headphones rely more on padding and insulation for this, leaving the circuitry to focus on the lower frequencies.
It cost me $AUS 120 including express 3 day FedEx International Priority shipping (North Carolina, USA -> Sydney, Australia).
The problem is that I have now broken a total of four hinges, though… Should I expect the fifth hinge to last much longer?
Their tiny earpieces rest on the outer ear or need to be inserted into the ear canal; some models include ear clips for a more secure fit. While ear-pad headphones can have closed designs that cover the ears, they are never fully sealed as full-size circumaural models are. Because of their size and their acoustic isolation, full-size headphones are often considered to be better suited to home use rather than as a portable option. The clip holding the band together at the top was already broken when I pulled them out of the box.
The joint where the earpieces fold in on themselves (there is a little pin hinge) broke clean off. Given that I’ve had two pairs, and both have broken on the plastic bits, they really need to look how brittle that plastic is. They have good audio quality, block out most of the plane noise and are light and comfortable.
This signal is an inverted copy of the original sound wave, which then travel together into your ear.


While the noise-cancelling headphones and the regular headphones have their own niches, the noise-reducing headphones are perfect for any occasion. When I'm not watching sports, I'm listening to music and thinking deep thoughts about sound.
If you occasionally experience ringing in your ears after listening to loud music or other sounds, take heed.
Noise cancelling headphones enable you to hear your music without blowing out your eardrums. However the best passive noise cancelling headphones are heavier and bulkier than normal headphones. They also help alleviate fatigue when travelling, which can result from exposure to low-frequency noise for an extended period of time. I am guilty of turning up my earphones, but hopefully I haven’t suffered too much hearing loss. Had no trouble opening them, but once opende I can’t figure out how to fold them up again.
As far as durability goes, I’ve slept many nights in them while flying and they survived well. The waves interfere with each other, called destructive interference, and no sound reaches your ear.
Perhaps someone in San Francisco, or New York, or Los Angeles would find the occasion to use them much more than I would. There is nothing I appreciate more than exploring new territories and gathering information about the world around me.
You can even use noise cancelling headphones if you don’t want to listen to another audio source but do want to cancel out background noise. I recently had the problem where the hinge broke and on calling the company and speaking with Dave in customer service he immediately offered to mail me a new hinge free of charge. Or you can choose what Bose calls Aware mode and let some of it in—all while keeping your headphones on.
But when you’re sitting on an airplane, trying to sleep next to the roaring engines, and you have a choice between turning up the volume—greatly—and cancelling the noise entirely, what would you choose?
I’ll be writing mostly about new gadgets, emerging trends, and my work-related travels to other lands.
I own several other pairs of noise cancelling headphones from other manufacturers but these are my firm favorites.
The QuietComfort 20 comes in two versions: the 20 works with Android and Blackberry phones and the 20i is for Apple iDevices. They include Bose’s proprietary StayHear+ ear tips and TriPort® technology with Active EQ to give music depth and balance.
