Okay we all want the noise cancelling ones by you know who but some of us can't afford them. So these are a good value. They fit over the entire ear and are comfortable. Okay the color is not my favorite but who cares. The instructions are very clear. The noise cancelling is quite good as I could not hear my loud 21 year old son over these, could only hear other sounds during a very soft piece of music. The phones do not come with any feature to make your audio device louder or change the bass or have it's own equalizer. I like how the battery operated (battery included) noise cancelling feature can be turned on and off and that the headphones can still be used if the noise cancelling battery dies or is turned off. There is also an indicator light to let you know if you have that feature on or if the battery is dying or not. An adapter is included for devices that the cord can't fit into. I tried every type of music and some music and tv videos. All good. Won't blow you out of the room but for the first time the equalizer feature on my audio device was noticeable with these headphones. Could hear some sounds that were inaudible with the three other headphones I previously owned. Tried classical to pop to punk to alternative. All sound great. Wont be any louder than your original audio source but sound slightly better. I think these are a good value although not sure how long the material will hold up. Cushioned and comfy. Adjustable. Still we all want the good dr.'s headphones. But those of us who can't swing that price, these are good.
