Weight isn't an important metric unless it's greater than the threshold of uncomfortableness. The majority of the weight difference comes from the extra battery which is a tradeoff. Similarly for volume, in which the case dimensions is the important metric. Once again the volume is a battery tradeoff. As for water resistance yes, the buds+ are IP2X versus IP4X. Under normal use this isn't important, but if argued this is the better point than bulkiness. https://www.rtings.com/headphones/tools/compare/samsung-galaxy-buds-truly-wireless-vs-apple-airpods-pro-truly-wireless/792/1625 https://www.rtings.com/headphones/tools/compare/samsung-gala... The point is that these are comparable devices and repairability doesn't have to make the drastic tradeoffs as your example of the fairphone 3.
