## Questions & Answers

**Q: Where can I get another aux cable?**
A: On Amazon.
 I recommend the marshall  aux
 it has a great microphone and it has a coil which makes it very comfortable to be walking around without it getting caught on stuff or just not feeling like u have too much cable when working on a laptop.

**Q: Is this recommended to use for online conferencing? is mic quality good?**
A: Yes. I have used it for about 10 days for teams/zoom meetings, the mic and speaker work very well for me.

**Q: Do they have transparent mode like more expensive models? And if not, is it possible to be reasonably aware of the surroundings when using them?**
A: Answer to @ShakyJake, you mentioned that you are unable to turn it off the "Transparency Mode" or the pass-through sounds that are made ambiently around you, like voices, crinkling paper, and typing. This is not the same as ANC(Active Noice Cancellation) which removes only the ambient hum of the room like a fan, refrigerator, or airplane.

This particular headset actually has two BlueTooth Connections or "drivers" on windows and mac. 
"Headphones (LE-HD 450BT Stereo)" & "Headset (HD 450BT Hands-Free AG Audio)"
Mobile devices seem to auto-switch between these depending on if they are utilizing the mic in the Headset or not.

Headphones (LE-HD 450BT Stereo): Does not utilize Transparency Mode, however ANC can be toggled. (Set this as "Default" if you do not want to here the Transparency mode)
Headset (HD 450BT Hands-Free AG Audio): Seems to default Transparency Mode ON, and ANC can also be toggled when this is active as well. (If you make a lot of calls and utilize the mic setting this to "Default" may be more useful) If you use the Assistant button, this will automatically switch to this driver, but will revert if you have the headphones selected as "Default".

**Extra Notes**
If you have a 5.0 BlueTooth (internal or as an adapter) for your computer both of these are able to connect and you can toggle between these in your sound settings. Most modern mobile devices as of July 2016+ have this installed but you may use the AIDA64 app on the Google Play store to see if it's in your device.
Apple Users: iPhone 8, iPhone 8 Plus, iPhone X, HomePod, and the 2018 MacBook Pro with Touch Bar all (and newer devices) utilize the 5.0 or newer BlueTooth.
I do not know what happens if you have an older version of BlueTooth, however, I speculate that switching between the two drivers may be clunky, and slower than it already is. However they will still connect, you may just run into issues connecting other devices simultaneously like a mouse and keyboard.
The S 450BT WILL usually prioritize headphone mode, however, I hope this helps if you were confused.
If you use the Headphone Jack it will put the headphones in Flight Mode and deactivate all BlueTooth Connections.

Hope this helps!

**Q: Do the headphones come with a charger or do I need to buy one separately?**
A: The headphones come with usb cable for charging, but no adaptor.
