Grado SR60s are highly efficient and offer superior sound at a very reasonable $70. I use them with my ipod and continue to be amazed at the clean highs and tight bass. They play as loud as you'd want with an MP3 player since they're very efficient. Sound as good as headphones priced at twice their cost, and have the features you asked for. Try a google search for reviews.
