Guys, look at the price. These are actually cheaper than replacing your piece of crap head phones that apple provides. I travel frequently on planes, buses, trains, etc. The noise reduction is exactly what one needs. Enough to forget about the surrounding world, but be conscious of the world around you. Use the provided different sized buds to find the best fit for your ear. The better the fit, the better the sound, the better your music. For size and price 10's all the way around. The volume adjust is helpful when music volume levels vary or in an environment with changing volumes. I have never had an issue in the year of use. I have yet to blow them out, or have a problem with tangling or tearing. To get the right seal, you have to find the right size of bud (provided 3 different sizes + case) and the sound will be great. You will love the product for the price.
