Im in LOVE! As in the past, quality seems fine. Bought a certified refurbished pair too, and had no problem whatsoever. That said, these have only been on the market for 3-4 months at the time of this review. I can’t say anything about the durability, but so far it’s been great. Extenders do not work with Apple or Bose products, cannot change sound or songs! Ok, so this is going to be a bit long winded but Im speaking to my specific expectations vs my experience. I will be returning one, don’t know which one yet. The range of bud tips is beyond what ever was expected. Absolutely, these sandals met my expectations.
