Third work out head phones didnt pair and now wont pair at all. Not worth the investment. It works beautifully and I particularly love that I can set it to turn off after an hour (rare for me to need longer to get to sleep) so the battery lasts about a week between charges. I’m not sure if it’s simple to remove as I haven’t needed to remove, I only use wireless chargers. Sooo comfortable to wear and walk in. - finally the Jabra software was easier to use, not glitchy, and offered tweaks that are more useful on a daily basis than the Bose. I have locks with round keys or distinct top and bottom you can work in low light. I had to replace my old power antenna motor on my Acura integra and I really didnt want to replace it with an old bulky transmitter. I havent worn them for more than an hour or two so far, but Ive had no issues with fatigue. It was easy to assemble and it is super sturdy!
