My teen daughter uses these every day, and they work great!  She likes them because they block out noise so she can concentrate on homework, and they have good sound quality. She has used them for over a year and the only problem she has had is one the speakers broke where it connects to the headband. I was able to take it apart and super glue the piece back together & they are good as new again. I am buying my other child a set for Christmas this year.

Bought 2 sets for my daughter for Christmas. She listens to a lot of audio books and she loves these. They are noise cancelling and she says they are really good for her books!

Daughter purchased these for the gym and they are a little big for her ears but they still work great. There is a blue blinking light that flashes about every 15 seconds or so when you are using them so if that'd annoy you find another set. She just keeps her hair down and you can't even see them at all then. She is very picky about how much bass a set of headphones has and she said that they have great sound. She can also leave her phone in a room and walk two rooms away and still have perfect connection. The little travel case is super handy to just clip to your gym bag. Also, the battery life is great! She wears them for 3hrs (3 workout sessions) on super high volume before it says "battery level medium". I would recommend these!!

My daughter loves watching movies on my iPad when on airplanes and while my husband and I are watching our shows.  She also LOVES to make sure everyone can hear her shows!!  These headphones are perfect for her because she just thinks she has a hat on and it doesn't bother her ears!  She thinks it's pretty cool to have the sound directly in her ears, we've been "practicing" wearing them at home for a flight in a week and I think she'll do great with these headphones on the airplane!!

The headphones work great for blocking noise.  I use ear plugs as well. I have small ears and still have trouble getting them in a comfortable position. Maybe they could have a little larger cup.

They really do block out most of the chronic sound nearby -- turning noise cancellation on and off is a huge difference.. They work dramatically better at this than the $45 audio-technica ones.  Surprisingly, they don't feel that tight but they don't fall out. Sound quality is great. I understand that the battery is going to last a very long time but it is non-replaceable and that doesn't feel right at this price.

I bought these as a gift for my girlfriend. She is very pleased with them. They are advertised as "over the ear" but they are definitely too small to go over the ear. While this would be a deal breaker for me, she prefers on ear. With that in mind, they sit nicely and do a great job of noise isolation. The sound is good and battery life is well within reason. I am taking away one star because they feel a little cheap, and I have my doubts about the longevity of the hinges.

Bought these for my friend who drives a loud car.  I know he loves his exhaust but he can't hear what I'm saying when he arrives LOL.  I wanted something that would provide quality sound (meaning he could still enjoy his subi rumble) but would attenuate it, preferrably without coloring the sound.  These worked perfect!

I tried them out when I got them (and cleaned them before giving them to him of course) and listened to some music really loud.  Works great!  No complaints.  I can have a conversation with someone while wearing them too.  Do note, they don't reject as much sound as traditional earplugs but they sound better.

They also do not produce any strange and annoying reverberances of yourself talking, as I've noticed with some cheaper earbuds.  Very good.

These are great--they block more noise than I was expecting and are lightweight.  They fit snugly over the ear and may need to be loosened a bit before use.  I am really pleased with them.

I bought these for my toddler son, and they work great!  I was able to try them on to check them out, and he actually wore them which is a minor miracle.  They have a great fit and the earmuffs are pretty comfortable.  We went to a shooting event and ear protection was a must.  I would definitely recommend these to anyone looking for ear protection for young children.

They work very well at blocking out light and heat (and actually a little noise too!)  Great quality!  Highly recommend!!

I got these for my wife who drives a 1999 Jeep Cherokee on the interstate highway every day.  While they don't eliminate all noise, they allow her to hear traffic noise and as she said, "They work well enough that I won't drive without them now."

My wife has hearing trouble and I got these for her. She loves them. Great sound quality and they don't block her ears from hearing activity around her. I might end up getting a set for myself.

The ear muffs and they work great! Thanks for following up and thank you for selling a product to save my hearing from my drumming!

My girlfriend really likes these. They're discreet for her shared office, and give a little bass boost that she likes

Great product! There is a setting so you can block out loud noises, but you can still hear talking or whispering.

So far so good. I have tinitis so listening to music at lower levels is appreciated as to not exacerbate the problem. These work well blocking out environmental noise without having to drown that noise out. With my stock headphones that came with the device I would have to crank everything up to 2/3-3/4 max to not hear my roommate, but I'm at 50% right now and it is doing a great job! The package has some interesting artwork as well. A guy with flames for this coloration.

In case you can't tell from the photos posted the cord is actually some sort of high-quality fabric like weave. The wire from the jack is set at an angle so hopefully there won't be any issues like those that go straight out of the jack.

Also, just tested out left/right and it appears the side with the mic attached is the left side (I don't think the guy on Youtube was jacking with me at least)
