Allow me to step in here - as a seasoned audiophile who has owned well over 30 different headphones (over as many years) and attended headphone only trade shows, I can tell you unequivocally that they are one of, if not THE best bargains in all of audio. I currently have a electrostatic-based headphone system totaling slightly over $20k, but needed a quality pair of cans for use with my iPad and for travel, etc. I purchased a pair of the 400se about a year ago and am continually amazed at how good these are - ESPECIALLY at the price. When my non-audiophile (& less crazy) friends ask me to recommend a good full-size pair of headphones, the 400se are always my first choice. (BTW, I have owned no less than 6 different HiFiMan headphones, over many years, and can attest that this is a great and well established headphone manufacturer). Don’t hesitate - BUY THESE. You and your ears will thank me later. Cheers!
