Title: MDR-EX81LP
Review: The sony EX-81 is the best noise reduction low bass producing ear phones I have ever tried but the fit is horrible, the over the ear hoops are a "one size fits all" approach and are not moldable. I would recomend the EX-71's instead it is the same as the 81's but without the hoops, they tend to stay put fairly well durring activity despite the lack of over the ear band.
