Ive purchased 3 pair of these earphones because initially I liked the first pair but shortly after they stopped working I thought because of maybe pulling them out of my purse. Easy to assemble, lightweight but sturdy and good quality. They feel very durable because the wire that wraps around your head is relatively thick compared with some of my other headphones. On top of which, the mounting bracket for the mic is useless as it limps over under the weight of the mic that it comes with and supposed to hold up. The JetStream is considerably quieter than the Roundbars at speeds below 45mph, even when my previous Roundbars had a wind fairing. The rest of the slipper looks just fine. Whether you?re using them for a virtual meeting or running they will stay in place. If you have any arch to the top or bottom of your feet be aware of this. Phone holder part ratchets pretty wide, I was able to easily fit a Pixel 3XL and a Note 20 in it. I paid $144 shipped each.
