Music production related gifts for boyfriend

We've been together for almost 5 years now and I've been successful so far on the gift giving side of things. I'd like to gift him something this christmas that fits in with some of his specific interests but I don't know that much about them, and he's one of those people that always just buys himself things that he wants.

He's big into phone tech, music production, nfl cheifs, red dead redemption and home decor. I've gifted him a lot of things on these fronts but this time I kinda want to get him something music production related. He doesn't play any instruments but he's really good at making music on his pc and he even studied it for a bit. I'm really not sure what would be good as a gift in this area.
