(Not the Apple-style cords—so no lightning or USB-C style cords will work.) **Q: Do you think this would be a good option for a bus driver doing a tour for senior?** A: Yes it has amazing output for a small speaker. **Q: Am I able to have two microphones that link up with this speaker?** A: I do not know, but you would probably be more likely interested in a public PA system like Anchor. **Q: Does the wireless headset stay on when moving around? I would be using it to teach group fitness classes.** A: I am using it to teach an outside fitness class and it does work when you are moving around. I have found though that when I lay down it fades in and out, so I usually take it off my head at that point. You do have to hold the mic pretty close to your mouth. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Teacher Must-have *by P***E on February 3, 2023* Product delivered sooner than expected.
