Question

2. Kate is listening to music with headphones connected to a smart phone.

3. Kate is listening to music wearing headphone attached to a smart phone.

(Are the sentences grammatical? Would you correct errors? Thank you.)

Answer 1

1 would be correct if you use the singular form: "headset."

2 is correct.

3 would be correct if you use the plural form: "headphones."

(A headset is made up of headphones ... but not vice versa!)

Answer 2

Also in #1, the word "a" needs to occur before "headset."
