As an Audiophile i really think the Nothing Ear are ok and and Headphone 1 is ok too. But both are limited in their sound do to theire low price.
But im Sure if they would do IEMs for about 300€$£ and over-ears for about 500-600£€ they could really shake up the Market in Terms of Soundquality while having theire unique Design. Is 150 or 300 really the Limit for you what soundquality is worth to you?$
