Definitely not the same charge as orignal purchase, If I had to guess, I would say 65% after four years? I forgot when they came out. Either way, they are so cheap now and there are so many brands go for it. I like Sonys the best since they do everything well minus being bulky and heavy, but do research, find out if you have small ears and buy what you need. If you want noise cancelling, to my knowledge Sony>Bose>AKG but it changes every quarter so this will change by the time you read this. I laugh when people post "omg these are the worst", or "these are the best" since there are so many variables with hearing/ear shape, device you are connecting to, codec etc.
