Question: Is there sufficient noise cancellation for use on airplane?
Document: Extremely comfortable and user-friendly. Sound is excellent -- it surprised me to discover that this sound (though not reference quality) was possible via Bluetooth. Noise cancellation is quite good for road noise and airplanes. More than once, I have taken off the headphones in flight and been jarred by how loud the engine noise was. The padding is comfortable and the headphones, though moderately heavy, are not burdensome.If you've never used active noise cancellation before, you must understand what it can do. Droning noises, like road noise and airplane engines, are nearly eliminated.
I am not an audiophile but I do travel by airplane a lot. The sound is terrific, battery life is good, noise canceling is wonderful. The iPhone app to control the headphones is a stroke of genius. I have purchased a number of headphones to use while flying, always to be disappointed. These do not disappoint.
They work great on an airplane, in a data center, they work so-so. If it is possible to make this more effective for the surroundings, that would make them better than any of the other noise canceling I have tried.3. (this would take an optional accessory) An off headphone battery charger. I don't know why they opted for an 800mAh battery other than weight. It does not seem like the battery casing is full and I only get about 5 hours of time with it. Assuming they cant get any more in there, having an optional stand alone battery charger that can be used while the headphones are in use would allow someone to charge one battery while the other draining would be the next best thing.
These BlueTooth headphones are practically perfect. The easily paired with my laptop and my iPhone. The noise cancellation is good enough so I can use them when mowing the lawn and the sound quality is outstanding. The touch controls are convenient and easy to learn, and the programming app for the iPhone works perfectly.
They get kind of uncomfortable for me to wear after a few hours. I wouldn't even attempt running with them.CONTROLSThe touch controls are cool for a while but eventually the gimmick wears off. There is no way to adjust the features like noise cancellation, EQ, or Concert Hall without pairing the headphones to your phone and using the app. I use them with my PC using a bluetooth adapter .
I love the way look and sound. The noise cancellation is amazing and the clarity is awesome. The touch panel on the side makes it easy to use. Its Bluetooth and you can use the wire when the battery is dead.. that makes it even more cool. They fit comfortably around my ear and they are not too heavy. The cushion in the top make it really comfortable. I used the Bose wireless Bluetooth headset before and I returned them in exchange of these.. and I am so glad I did!!
First, one tiny negative that won't be an issue for most people. I wish the diameter of the ear cups was a few millimeters larger (I have a big head and large ears).With that out of the way I'm extremely happy with my Zik headphones. The noise cancellation is only average but it makes a huge difference in typical outdoor use (e.g., when walking my dogs or doing yard work). With that feature enabled I find I rarely need more than the minimum volume level when listening to podcasts and audiobooks.
The leather headband is padded and not too wide - they look less bulky and compact for travel.+ Wireless design with great connectivity - no noticeable sound quality issues+ Cloth cables - hopefully they will last longer because of this+ Noise cancellation is good - Bose might be better but I have only tried these in stores+ Easy to remove battery cover (but see dislikes below)Cons:+ The batteries last less than 10 hours in Bluetooth and noise cancelling mode. I imagine for long flights in which you'd use the cable but use the noise cancelling, they will last longer.
Maintain the excellent Active Noise Cancellation feature.8. Maintain the ability to use the downloadable app to apply nifty sound effects and install firmware updates.Having clearly defined those aspects of the current Zik iteration that are not up for negotiation, let's talk about what can be improved. During my first 1,000 hours I've annotated a list of needed improvements. At the Zik price point, I consider all of these to be "must have" features for the 2.0 version; nevertheless, the following list is prioritized according to my perception as "most crucial" to "least crucial:"1.
Works best with mobile devices where you can use the app. However, there are still limitations. Battery life is also not as good as I'd hope.This has drivers for Windows and Mac, but these are basic, and somewhat finicky. By that, I mean they sometimes don't work and require me to &#34;forget the bluetooth connection&#34; and &#34;start over.&#34;My biggest pain: I tried using Skype on the Mac, and the Mic-support would often fail.Having said that, I like the noise-cancellation, although the &#34;negative sound pressure&#34; is a little too aggressive.
Answer: More than enough.  It puts others like Beats and Bose to shame in that department.  I use it on planes and in noisy data centers all the time.
