Brett Eldredge is honoring his grandfathers by keeping them close to his mind at all times.

The 31-year-old country star displayed a new set of in-ear monitors on social media Monday (May 22) that contain the names of his grandfathers on both the Eldredge and Vonderlage sides.

"My grandfathers were a big inspiration to me and big supporters of my dreams," Eldredge writes via Twitter. "These are their signatures and they live on through every song."

For those unfamiliar with in-ears, they are small monitors used by musicians to hear a customized onstage mix of instruments and vocals during a live performance. They're especially necessary for stadium acts, such as Eldredge, as most traditional onstage monitors don't provide as clear of sound for the performers in such large settings.

With Eldredge's customized in-ears (Ultimate Ears UE 7s, to be exact), he can now pay homage to a piece of his family — on both his mother's and father's side — with every note. It's perfect timing, as he is about to embark on a cross country tour that includes major summer festivals like Bayou Country Superfest at the Superdome in New Orleans and CMA Fest in Nashville, while also performing as a special guest on Luke Bryan's massive Huntin,' Fishin' and Lovin' Everyday Tour.

Eldredge is also encouraging fans to #SingWithBrett as part of an online promo for his latest single "Somethin' I'm Good At." The country crooner is asking fans to send videos of themselves singing his new song; Eldredge then shares his favorites on his social media channels.
