-Oxygen OS is by far one of my favorites of the phone, its lightweight and not bogged down by anything. Die Ohrpolster fingen sich schon nach 1 1/2 Jahren abzulösen und Austauschpolster mussten her. Like that it is waterproof to be able to use at the pool and beach CFexpress Typ B Karte benötigt und da sich die Preise eh kaum unterscheiden und das XQD Format früher oder später vom Markt verschwinden wird, habe ich eine 128GB CFexpress (CEB-G128) von Sony genommen. The petite size is just perfect for a mid-to-low heel and looks great with tall heels too. Same feel4. sound is good but the unit its self is low quality not worth 200. They are super light and comfortable, they come with only one cable with in-line microphone and a call/play/pause button, the sound is punchy and exciting which is good for noisy environments. Great price for a great headset though 5 sneaker, and the 13-1 is perfect with room to grow.
