Super easy, just pop out with a screwdriver 3. And that had nothing to do with the fit to the car (04 CR-V). Why? Because I have to have a pair at work, in my home office and in my backpack to listen to my phone when Im waiting on my son to finish his swimming lessons. O software é bastante rápido e fluido, nenhum app que eu usei chegou a travar, e consegue aguentar de boa diversos apps simultâneos sem reiniciar nenhum, quanto a jogos não sei sobre o desempenho, pois não utilizei pra isso, mas provavelmente deve ser satisfatório também. Half sizes order next size up. That is actually pretty great. Also, Id like to see the charger base be made with a bit more high quality material. The material used to make this product is super strong. These do run small. Their package includes two high-tension rings in black, and two low-tension rings in yellow.
