Not all ears are created equal. What sounds loud for one person, may barely reach the eardrums of another. That's why you hear some people listening to their devices with full volume that you can already hear the music even if she/he are wearing headphones. Or there are times when the audio setting is already too loud for you, and yet it just has barely climbed the aural charts. It would be great if there was a device that could tailor-fit your audio experience right? That's what Aumeo is aiming to be.
