The waterproofing is also very good as I have used this speaker for a few months in the shower without incident. Oh and if you manage to risk putting this on you it lasts for ten minutes before burning your skin. They still are okay to wear with socks. You can transfer it between vehicles and for most dashes will stick right on. Birkis fallen sehr sehr groß aus. So I have to return them???? For the price, this is a steal. The MacBook Air 2020, like the MacBook Air 2018 and 2019, has very poor thermal design because there is no pipe to connect the fan to the CPUs heatsink. Well reluctantly I tried them. So now, I have this thing and no idea how to finish putting it together.
