If you are talking about Fairphone’s TWS earphones, this might be of interest to you (sentence #3 – however, right now I am realizing that my original conclusion that the R and L earbuds will be available individually is not a total given from Miquel’s wording):
As for my own experience, so far I haven’t been in typical commuter or travellings situations with my TWS earphones yet. As uppercase, I always take the case with me as well when using the earphones outdoors. So far I haven’t even experienced an earbud dropping to the ground. I think one little-discussed advantage of wireless earphones is that while the mere risk of those falling out of the ears by themselves appears high at first thought, we still underestimate the impact of earphone wires getting entangled somewhere and suddenly ripping the things out of our ears with brute force. With wireless earphones, I can always sense in time when they might gradually lose contact and need readjustment.
