Juliana Chahayed

Also known as the "Phone Mic Gal", Juliana Chahayed is an internet personality (?) that makes covers of different songs, such as No Surprises by Radiohead and Fly Me To The Moon by Frank Sinatra (or the Neon Genesis Evangelion version of it, which she managed to sing for 10 HOUR STRAIGHT. Props to her!)

Her singing can be easily distinguished by the soft and calm guitar and voice, and the fact that she doesn't use a normal mic most of the time. She uses an old telephone mic instead, which makes the songs all the more soothing and pleasant to the ears.
In addition, she has made some of her own songs, so go check that out if you're interested!

Person 2: you mean the phone mic gal? Yeah, she's nice.
