I use it daily to get around (metro, RER) and for that it is not very convenient because it is not bulky, it is easily stored and not need to be pampered for the price it costs. I bought one about a year (do not expect to keep the centuries it's not a tank).
In summary this is a great helmet at this price, nomadic and can be supported by a higher-end headphones at home (like a Klipsh Image One that is fragile so little nomadic but is very comfortable and the sound is almost perfect).
