It does not come assembled,but if I can put it together,anyone can. Of course, if you are blasting them that may not be the case, but you should keep your volumes lower anyway if you like your hearing. The new one came fast today. First pair lasted 3+ year and i just bought a replacement pair. The screen is not a real touchscreen: it has one button you use to do everything. Youll notice the ANC letters are already half way worn off. I work in healthcare and bought these over a year ago to replace my danscos. Too many other type shoes are made for wide feet. I AM SO THANKFUL it comes with an extender because I definelty would not have been able to fit the XS without it. Something people need to know about the replaceable silicone ear tips: when not using these(or any Bluetooth devices) dont leave them hanging around your neck!
