A:AnswerYes they will connect to just about any bluetooth connection. I have them connected to my Samsung S7 tablet, Microsoft Surface 4, and my phones. They can only be connected in use to one item at a time. So you cannot easily switch between items without going into the app
A:AnswerWhen you open the case, after letting the earphones charge, you should only take out the right earbud so it will wake up and connect to your phone while the other one remains sleep.
A:AnswerIf your laptop has Bluetooth, more specifically 5.0 or 5.1, they should work great. I use it for Zoom quite a bit since I purchased them and go between these and a nice pair of wired headphones. If you plan to use the microphone on them, set your default listening device to Momentum TW2 (Headset). If you are using the built-in mic on your computer, or a separate mic, you might want to set your default device to Momentum TW2 (Stereo) for Zoom to hear everyone in better audio quality. I noticed the latter was only feasible when you use a different mic than the ones in the earbuds because when you use the earbuds mic, it forces your audio to the headset channel. It's not a bad quality, but it's definitely not as good as the stereo channel quality.
PS. If your laptop doesn't have BT 5.0 or 5.1, I recommend the ASUS USB-BT500 Bluetooth adapter. I picked one of those up for my desktop and the Sennheiser earbuds work perfectly through that.
A:AnswerI can't tell you the db rating for the ANC but I can tell you there's no way they are suitable for the gun range. There is very little noise reduction when you turn it on, its almost like they're not on.
You really should buy hearing protection designed for the range, really. Its not worth losing your hearing to try to save a few bucks.
