Hifiman HE-4XX is a great headphone for those who want the planar slam and sound stage for a much more amenable price. The 4XX is decently efficient and can be run off of a phone, though I recommend an entry dongle such as the Dawn Pro from Moondrop or the KA-1 from Fiio. I will include both a balanced XLR cable and the stock 3.5mm right angle connector. There is nothing wrong with the product besides some slight cosmetic defects on the faux leather headband (see pictures). However this can be covered with the included head pad (cleaned and sanitized). Overall it's a great headphone, I just happened to upgrade to an Arya Organic, so I need to downsize somewhere. It's a perfect entry into planar magnetic headphones and gives you the option to use the headphone in either a balanced or single ended system. *Note* There is some slight wear on the headband as the faux leather has peeled somewhat. This does not affect the sound quality of the headphones. Includes: HE-4XX headphone 2 new lambskin pads from Brainwavz The original box and packaging 3.5mm stock right angle headphone cable 3.5mm to 6.35mm (1/4 inch) adapter 4 pin XLR balanced headphone cable A new headband cover/pad (I got a slight hotspot on the top of my head without a little extra padding.)
