HEDD HEDDphone Air Motion Transformer Headphones

The overall sound signature is amazing. It is a warm neutral signature. Its presented with a flat profile, all instruments and voices are natural. The clarity, depth, imaging, separation of instruments are awesome. These are on the level of the Senn HD 800s, maybe better depending on the listener. I am audio engineer and I use these for my work. It will need a high power quality amp to get the best out of them. However they still give you good sound without an amp, I am not going to sit here and say its an absolute must, like most reviews and websites say, its just silly to say they don't put out sound unless you get an amp. The type of amp matters though. As I started with the THX 789, it was ok, but it was below others price more when tried. I upgraded to a singular amp, the sound changed quite a bit and better. I also use them with my Onkyo Denon AVR-X2700H, it brought out the depth and separation of instruments to a whole new level. I would say there veryfew headphones that can compete sound wise and technically at €1899 and below, they compete in the €3000k range with Hifiman He1000se. Heddphone do need sometime to break in at least 20 hrs. I recommend if price is not an issue as if you buy these theres no need to buy €3k to €4k priced headphones, unless you have specific taste as in bright or warm sounds, very little difference, unless you creaping in the €5k range.
