Very studio-like. While they improve on the overall sound quality through slightly better drivers and aptX, they also fall short in the tuning. **Do Not Use Any Harsh Chemicals To Clean Them Or Any Sharp Object**There are "Preamium" earbuds, that has a filter cover inside the memory foam earbuds, to keep earwax out from getting into the fine metal screen. Amazons prices for Birkenstocks are amazing- I did have to check out several vendors to find my size in the style I wanted. I love the brushed gold. In CarPlay, just use the screen controls. All accessories were included. We go through all 4 seasons where we live and as a family of six, we just have a lot shoes! The shipping took a little long but was pretty accurate when they estimated the ship date arrival. Its going to cost me over $100 to ship back as they wont give return paid label.
