The first 30 seconds of listening to these was like the sensation of getting into a very warm salt bath after a marathon. My whole body relaxed and chills ran down my spine. No distortion. I’m an analytical listener, usually listening to compositions or performances I recorded myself or attended live so I listen for pronounced blemishes from the pieces I intimately know. These CRBNs presented everything I threw their way exactly the way I expected the recordings to sound. And I don’t have an extremely expensive electrostatic amplifier. Just the HIFIMAN Jade II. These are truly special headphones. So glad I finally snatched these up.
