I have been enjoying Bose Frames since it has been introduced. It really changed my life because it set my ears free. But one thing has been my continuing concern about using it, because Bose Frames seems to have problem with power. I bought it from Best Buy with Geek Squad insurance, and I changed it for 5 times due to the power problem, which I have the problem again. Now, I inquired Bose Korea to get a replacement, because I am in Korea. Unfortunately, they don’t sell Bose Frames Alto Large but only small one. I am only allowed to get replacement to the small one. In this case, is there any way that I could get replacement for large one in Korea? Thank you!
