HEDD HEDDPHONEONE Reviews

Great for Hifi listening, NOT so much Audio Production work

By StewC
Rated 4 out of 5
Date: 2023-03-24

I am audio engineer. The clarity, detail, and separation of instruments, and soundstage is great, with an almost 3D sound, but not surgical to reveal errors . Sounds come from the back, top, and side. The Sound is in between Planar and Electrostatic. Its closer to a warm natural sound. These are not bass heavy, the whole spectrum is lean to flat sounding. My main issue, is that these were marketed to music producers/engineers and they have it wrong. The sound is too spacious, smooth, warm and full bodied and not that dynamic. The timbre is not snappy or sharp how I like it. They are not revealing enough to pin point errors in music. Sound engineers need aggressive, intimate and microscopic detail. I used sources such as Sound reference, Waves and Can Opener to get the sound ready for mixing or mastering. I have Dan Clark Ether C as my close back and they are awesome for my needs. I will go with the Audeze MM 500 or Hifiman He1000se instead as my open backs. Heddphone leans towards Audiophile and listening to music for enjoyment only at least for me.

Awesome sound

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.
