It’s not easy to stiffen up a framework this size. Even Airpods only get about 5 hours, while these reliably offer close to 8 hours - which makes a huge difference. To prevent them from coming off so easily I suggest using a small rubberband to keep them securely on. Makes less noise driving than my previous racks. The controls and connectivity were glitchy as well. Ok cool, nbd Ill just pop this baby on like a shirt. Its not there in the 9s so I am more comfortable walking in the smaller size for longer periods of time. This thing is a joke. But, hey, these are tiny miracles, considering the quality sound they put out and sure as heck worth this price. But I didnt.
