I bought the 18 to 24 month set thinking it would be perfect for my son for the fall/winter. Biggest issue is durability. I have small ear canals and it can be hard to find earbuds that fit without falling out. The added benefit of having the ANC and BT are just bonuses. They must be comfortable as well as she wears them out playing and on walks. Great price too mone was 12. I’ve wasted a lot of time on something that should take 2 minutes. I love these sandles, its winter where I live but that hasnt stopped me from wearing my super cool new Boss Sandals. They need to fix this. While it is slightly better sound, volume and some extra options it is not $129.
