In that case you may as well buy a flashy watch. No conventionally shaped passive headset is ever going to be much good, unless it clamps onto your head like a vice. ANR is the only way to go. Unfortunately the cheap ANRs aren't much good, which is why so many people go around saying that all fancy headsets are a waste of money.
