It's no secret that wired headphones deliver better quality audio than wireless ones. With their well-trained ears, they can detect even the slightest difference in audio quality. This is why both of them prefer wired headphones over wireless ones.
That sounds like a good option. Beats Studio3 Headphones have high-quality sound with active noise canceling, They also come with a carrying case and audio cable for added convenience. I think they would be a great choice.
