I use Nuraphones at work. Their main advantages are a gel-based ear surround and in-ear deliver of most non-bass sound, combined with environmental filtering and pass-through option if you need to hear around you. Also, they detect your hearing range though some sort of auditory feedback they're sensitive to, and are really clear as a result.
