No, the Ifi GoBlu. Great sound quality, great aesthetic, convenient size, garbage battery quality. I have had to send it in 3 times for swelling. Each time, I have buckled down more on making sure I was more careful with charging; using a smart charging or low power USBC AC adapter, then using only low voltage adapters, finally demanding they send me an AC adapter designed for it since they didn't include one.

Such a significant thing to cheap out on with a $200 piece of tech, especially when LiPo batteries are already so cheap. They also refused to send spare batteries as well this last time, which I am more than capable of replacing myself, to save ~3 weeks of time. I have decided that if it happens again, I will just find a comparable size/voltage battery and solder it in myself to spare myself the hassle.
