Both previous masks had buttons for volume control but they didn?t function. amazing for electronic music. Im quite sure the general sound quality has improved a bit too with the problem aside. Let me know if this review helps! I use them to commute in and they work perfect for that. They are beautiful. 5, they are too small now. Was great and convenient for days I wanted to ride when the weather wasn?t suitable outside. I will definitely be purchasing from Vandel in the future! I highly recommend these shoes!
