Bluetooth connectivity doesnt affect the quality in any way and theyre comparable with other more expensive wired variants I have. I also love how it grabs the earbuds as you lay them in and it instantly begins to charge and shows you the battery percentage. They feel a bit long. I have another pair that looked somewhat similar -- and no one knows they are crocs so fashionable -- thought this would be a great addition to my wardrobe, however they are really more croc like and not as fashionable as Id like. Anche lo stile è carino e particolare, considerando lo standard della marca Crocs. They are not flimsy. Range - Jlab has about 1/2 the range. The are cute and even half way comfortable, but not true to size. definitely good for r&b, hip hop, dance, and electronic. Instead of first quality NEW shoes, what Amazon sent me was used shoes in a plain cardboard mailing box.
