The day that I first received a pair of Nocs I thought they had two high of a treble and too low of a bass. They didn’t feel neutral.. But as I listened more to them I started to understand why they weren’t as warm as a pair of old speakers. The music I was listening to was not that great. I have been privileged of owning a 350 W sub that was placed inside of a glass enclosure with sound coming from the top, and a small speaker that had the most warm sound of any speakers I’ve owned. The two of them together sounded like an amplified version of the Bose Sound Link Mini. By a lot. And so after the DAC/AMP unit stopped working I purchased the Nocs NS 400-002’s. A pair of 105 db and 16 ohms versus the 96 db of the NS 200’s. To this day, these headphones are the ones I always keep coming back to because I have come to an understanding that not all artists know how to mix audio. The sound engineer for Lana Del Rey does amazing work. These headphones are the in between of audiophile and consumer level grade. It is the definition of what audio should sound like in the entire frequency spectrum without being warm like an old pair of speakers or a highly powered pair of headphones with 600 ohms of clarity and an O2 amp. Trying to listen to such a range lets you hear the imperfections a lot more clearer and that doesn’t make music enjoyable. It’s like telling a child Santa Claus isn’t real. You’ve removed a filter of clarity. Where the Nocs stand is… minimally designed lightweight earbuds made of aluminum/titanium. The difference being a subtle higher clarity in the 400’s and so on for the higher models. Buying anything higher than the Nocs price range is a waste of money.
