yup, the NH is no longer with me. Main reason was because I preferred the Elear for, well, everything.
The Elear has a more balanced signature, while the NH is overwhelmingly dark and warm at times. This may be great when you want a smooth, relaxed sound, but imo the Elear can do that too on lower volumes.
The NH has a magical ability to sound extremely dark (to me, anyway), while the treble details are still all there somehow. It's fun to listen to, but could never be a daily driver.
The Elear has a more pronounced, airy treble, but somehow I actually find it LESS harsh and fatiguing than the NH's treble.
So bottom line: The Elear is more balanced, airy and (imo) technically superior. The only thing the NH has on the Elear is it's warm, dark bassy signature, which some may prefer. But even then, the NH is more harsh and fatiguing to me than the Elear, so it was no reason for me to keep it.
Oh, and comfort is around the same, NH is lighter and has a nicer cable. Elear has softer pads.
