Question: are they on ear or over the ear?
Document: works about like ear plugs--deadens most noises, particularly constant ones (like motors) but voices and other variable noises are still audible. I plan to use in conjunction with ear plugs for more restful sleep on planes.
I plan on using these typically for the gym and also for trips. I have a pair of wireless Motorola in-the-ear headphones but I wanted a decent pair of over-ear noise cancelling and I think these are going to be perfect. Would definitely recommend these to anyone and don't regret my purchase at all.
I don't  have a lot of experience with headphones, and none  with noise cancelling until these. To  my surprise, the music sound gets brighter with the system on. Why, I don't know. They are fairly comfortable, but a little too warm for more than 30 minutes. The price is excellent. The cords are cheapo. Volume control is on the ear piece, not the cord. That's better for me.
Functionally these work great and I'm glad I didn't spend triple on a brand name pair. The block out a lot of low frequency noise (fans, cars, etc..) and some higher frequency noise.The microphone works as well as my apple ear pods mic. The sounds quality is fine for me.
I am not an audiophile.I like over the ear headphones because they reduce outside noise, and this is the first pair of noise cancelling headphones I have ever owned.These headphones are good. The sound quality is excellent, and the active noise cancelling works.I did end up returning them because either my ears are too big or the pad cushion is too close to the speaker.
There is a mesh pouch on the outside of the case, which you could put the accessories in, or other things, I could fit my phones in it, which is an LG Optimus G with an otter box case on it. The mic works on my Android phone. I'm not sure if the mic works on idevices, but I imagine it does. There is an on/ off switch for the NC on the right ear cup, as well as a volume controller.
I have a big head and big ears so while they don't cover my entire ear they seal well enough to not notice any gaps. Some people talk about the pressure one feels, but after about 2 minutes I was used to it.ConsBattery compartment is a pain in the butt to open. I was almost afraid I was going to break it. FYI it slides down, but not completely out of the way.
The cable is detachable, and it doesn't take much force to push the connector into the left ear cup, or pull the connector out.The i7 is built pretty well. I wouldn't call it a &#34;Tank&#34; build, but they are solid.Comfort: The i7's are an around ear-headphone, with a good amount of padding on the headband and on the ear cups. The pads are genuine leather, which are very comfortable.
Noise cancellation, while not as good as any of the Bose units I've used, is also pretty good. Like any over-the-ear headset it gets warm after extended periods but I knew that going in. I've not worn if for more than an hour so I can't comment on long-term comfort. Adjustment seems adequate for someone who wears a 7 1/2 hat.
I first used these on two recent transAtlantic flights, and found the over-ear cups comfortable. The noise-cancelling feature worked well. It reduced the noise of the aircraft engines from a loud roar to a low, dull drone which I found acceptable: I did not expect absolute silence with the noise-cancelling on. If you listen to the audio of music or a video, the remaining background noise tends to become unnoticeable.
Answer: Depends on the size of your ears. Personally, the bottom of my ears are "in" the cup of the headphone, but the top of my ears are "out" of the cup of the headphone. They feel very natural to me. I don't even notice where my ears are in relationship to the "cup" of the headphone.Also, I don't recall how many months (should be double digits by now) that I've been using these headphones, but they haven't lost any quality in that time period. I use them daily for 5-8 hours at a time and they have held up great! Wouldn't hesitate to purchase again.
