Pretty easy to assemble. #3 Bluetooth connection lost is constant on the Macbook. Super sturdy for our 2 mountain bikes with oversized wheels. are weighing you down too much then you can save some weight with this choice. It makes me question the authenticity. During the worst flare up I’ve ever had it got so bad I couldn’t walk due to foot and knee swelling and pain. I work two jobs and I was hoping these would work out. I tried granting it permission to everything except contacts but it just quits and when I start it again it asks for that permission again. Me gustó. You may be able to find what you need in your price range with another headset as I now see them being sold used for $40+ here, but I really like the design and the open ear headphone, so I would recommend these if you have the same need that I have even if you have to pay a little more.
