I am selling my extra HE1000se because I really don’t need 2 pair. They have been worn for <5 hours but burned in for about 75 hours. Included are all accessories (3.5mm cable, 4.4mm balance cable, and 6.3mm adapter), instruction manual, case, and warranty card. Do your headphones sound open and airy and natural? Is the bass tight with deep extension and punch? Is the midrange clean and well-defined? Is the treble clear and extended? Does the tonality sound natural? Do you hear a 3D sound stage? Is the image sharp and delineated? If you answered “no” to any of these questions, then the HE1000se may be just what you are looking for. I find it has a more robust presentation than the HE1000 v2, which seems laid back in comparison. In fact, I find the HE1000se to be superior in almost every way. Some reviewers prefer it over their Utopia. My only quibble is that the midrange is slightly recessed relative to the v2. Boosting the 1k frequency by 1 dB brings the midrange to its proper position, and now the sound is perfect. There is a reason Hifiman named this headphone se rather than v3. It is more a completely new product than an update of the v2. Buyer is responsible for 3% PayPal fee and actual insured shipping cost.
