Question: Does the sound leak when the sound us loud?  I played a set of headphones loud and everyone on the plane was disturbed.
Document: I am very glad that I purchased these over Beats or Bose. Not saying anything is wrong with the Beats or Bose but the price is really high. This Sony set has really good sound and volume. I know there is a break in period with the headset but the sound quality is real good long before they are broken in. I have used them for two days and counting on the first charge. The volume is quite loud and the sound is exceptionally well when using an app like WinAmp and its EQ.
If you like bass, you probably won't like these... if you like treble, you'll probably do. note: this is with noise cancellation.Without Noise cancellation - more like an 8. (All you need is batteries for NC)Noise Cancellation - 9.5/10 Fantastic... kind of. If you are on a plane, bus, or the air conditioner is too loud, they block the noise out so that if you have music on, you won't hear the background noise.
These headphones are awesome. First off bluetooth is the way to go. No wires no tangles. Sound and Bass were awesome. The headphones worked flawlessly on a 10 hr. Plane ride to europe. Nice and soft ear cups. No pressure from extended use. When I wanted to use the in flight movies I plugged in these headphones to the plane. So I had comfortable noise cancelling ear phones on my trip. The charge lasts forever. I used them continuously over 2 days with no dead batteries.
I second all the reviews that tout the sound quality, build quality, and comfort of these headphones. For someone who flies fairly often for work, these headphones have been the best "upgrade" to air travel that can be bought for under $200. Indeed, they are worth much more than their price for the following reasons.1. They block out a substantial amount of engine noise and loud conversation.2.
I like these. They are a good fit and are less expensive then the other headphones out there. I havent had a chacne to fly with them yet. I feel like they will work well on the plane as well
Moreover, even if you don't have a AAA battery available you can still use them. In short they are everything I have ever wanted in a set of headphones plus they sound great! They are as every bit as crisp as the MDR 7506 and extremely comfortable. I bought them at Costco for $179.00 plus tax. A real steal!
There are a ton of headphones in this category, so I set about trying a few of them out.Bose AE2: excellent fit and comfort, by far the lightest pair I tried. The build quality was good, but surprisingly plastic-feeling. What killed these for me was the sound quality. Although lows and highs were well-defined, the mids were too punchy, especially the high-mids, which sounded over-emphasized.
I have been using LG Tone+ (HBS-730) for years now, because nothing wireless outdid it. However, I hate earphones, and even turned to KickStarter to find a solution.These puppies came out, and suddenly, I find myself with headphones that work great in the plane, during a commute, and while working for hours.
I've had some experience using a bluetooth speaker set up with my computer before, but my main gripe has always been the small latency where the sound gets delayed by a split of a second (or more..). This is not a problem for listening to music, but it's not ideal for watching movies or gaming on the computer.I figured it would be the same story with these bluetooth headphones, but I'm happy to find that using these headphones is nothing like what I've experienced with my previous bluetooth speakers.
The sound quality is absolutely wonderful and I would have no hesitation recommending them over the Bose for anyone. Just the apt-x quality alone is worth the money, not to mention the AAC quality from an iPhone. To save space, I have iTunes set to give me 256kb AAC copies of music on the phone and these headphones are just great!There are times that I wish they were a little more isolating, but that's because I have very sensitive ears. No fault of the headphones.
Answer: I use it on a daily basis in my office. No one was ever bothered. I also tested it having others hear classical music with high volume and I couldn't notice any leaks. Hope it helps.
