The four piece have made the final of this year's series, but there have been some bumps along the way.
"The best thing has been being able to focus solely on music. The worst thing though is Ashley chewing my ear or [Mustafa's] snoring!" Myles said.
Ashley spilled: "There are a few habits [in the band] that are equally bad. If I'm being honest, Jamaal doesn't really have any bad habits. Jam is alright. He's the angel kid. But Mus' snoring is powerful."
Mustafa admitted to Digital Spy: "I had to find somewhere else to sleep. I was sleeping on bean bags for awhile. But it's cool, it was quite comfortable. I had to leave because Ashley started crying one night basically.
"So I thought, you know what, rather than annoying three people, let me just annoy myself. I did it for them."
Despite the rows over snoring, of all things, the group say arguments will never break them up.
Myles said: "We are brothers and no argument will ever jeopardise us whatsoever."
Ashley agreed: "We have developed this skill where we will have an argument and it can get really heated, but it's never personal.
"Like it will genuinely be just about what we're discussing but once it's sorted, that's it."
"The best thing about doing The X Factor is probably just being together and being able to write music together," Myles concluded.
The X Factor 2017 airs LIVE on ITV Saturday and Sunday night with the live performances from London's ExCel centre.
As well as the songs from the contestants, there will also be a number of guests over the weekend.
Little Mix, Louis Tomlinson, Sam Smith and Pink have all so far been confirmed for performances across Saturday and Sunday.
