(See last photo) I guess placing powder coat steel plate in a bag. There is a delicious irony throughout. It’s so stinking cute I almost can’t stand it! I got these specifically because they go up the ankle/leg and stay on better. Its not a bad product; its actually probably the second-best headset around. Cant rate this brand any higher. My AirPod Pro charges, and my watch charges so it’s not a problem with connecting the top half to the bottom. These fit my needs perfectly. 0 adapter is included. I really regret losing my original pair of these same headphones - which were flawless.
