Repairability is good and will reduce waste, but I am not sure this is going to actually attract customers unless they’re already fans of Fairphone for other reasons (like ethics or sustainability or privacy or independence from big companies or whatever). To attract new customers, they need something else to stand out from a very crowded space, where there are many good choices as far as sound quality, mic quality, noise cancellation, etc. I am skeptical that these will be any better than the competition on those facets. And keep in mind, 150 Euros means it is competing with everything from budget sub-50 products on Amazon to AirPods.
