>Sorry, I did not have time to put my earphones on. *by saying sorry is apologizing which is polite. *This sentence is saying sorry for not having your earphones on. .............................................. >Sorry teacher. Let me put my earphones on. *This is saying sorry and give me a few seconds to put your headset on. ..................***..................***

"Give me a moment" and "hold on a second" are ways to ask someone to wait a short time why you do something and then can get back with them.

Yes, sometimes we may forget or be busy, or have just arrived from another location - There may be any number of reasons why you are not exactly one hundred percent organised! "One second please! I'm just organising my headphones." "No problem at all." "I'll be right with you!" "OK."

It sometimes happens that a student puts his/her headset (earphones and microphone) away from where he/she operates from, and, the lesson has just started. The student needs to quickly get the headset from where he/she had put them and wear them, and, make sure that they are functioning properly. If you find yourself in a situation like this, you may have to say to your teacher: Please give me a second to wear my earphones teacher. or Sorry teacher, I just need to wear my headset for a second.

If your teacher had said something that you couldn't hear, you would say: "Sorry! Can you repeat what you said? I hadn't put my earphones on!" But if they still hadn't said anything and you want to let them know that you're putting on your earphones, you can respectfully say: "Sorry! Can you repeat what you said? I hadn't put my earphones on!" They will wait for you to do so before beginning the lesson. Hope this helps!

Could you please give me a moment - A moment means a short time. There this means you are asking the teacher to just give you a few minutes because you want to wear your earphones.
