I own a Cam v2 and a vacuum cleaner. Very pleased with both, but concerned about what will happen if/when bits break on the vacuum. I would consider buying the headphones, but not until you offer replacement ear cushions (already in wishlist) and headband/battery (added to wishlist today).
Bottom line - in anticipation of EU regulation on repairability and recyclability being required built-in to product design being replicated in the US - I recommend you get ahead of the curve and do just that. If you were to survey your customers and ask them how important the environment is to them, I feel sure you would hear a resounding VERY !! If you also were to ask them whether they would pay a little more if products were fully repairable, with replacement parts available, and fully recyclable. I think you would also get a positive response.
In fact, you would differentiate yourselves even further from the generic hordes. Imagine - products and service people love, at a price they feel represents good value, and with longevity and environmental awareness built it. What’s not to like?
