Bull's Germany Delta IV RB Sound Review

My opinion on the Bull's Delta IV RB Sound

The Bull's Delta IV RB Sound clearly targets amateurs who want a full-featured electronic dartboard without going through an app or a Bluetooth connection. It reuses the signature ingredient of the Bull's RB Sound range: the voice of Russ Bray, "The Voice", the PDC's official caller/referee (the announcer who calls out scores, e.g. "180!"), accompanying every score and every leg finish. Here, it's paired with nine LED displays at tournament dimensions, a real selling point for game nights with several players.

With 38 games and 176 variants supporting up to 16 players or 8 teams, it clearly sits above the Flash RB Sound in terms of content. It still sits a notch below the Dartforce RB, higher up in the Bull's family, which offers even more games and a coin mechanism. The Delta IV RB Sound finds its place between the two: premium without being the flagship.

My test of the Bull's Delta IV RB Sound on the oche

On the oche, the two-hole segment does its job well: plastic tips are properly rejected and automatic scoring stays reliable, even with several players. The nine LED displays are a real comfort for evenings with friends or large family gatherings: everyone can follow their score without leaning toward the central display, which changes the atmosphere significantly for game formats with up to 16 players.

The unique sound effects and Russ Bray's voice remain the main hook of this board: they add real depth to games, even simple ones. With 38 games and 176 variants, there's plenty to vary game nights without always falling back on classic 501.

Durability of the Bull's Delta IV RB Sound

With a score of 7/10, the Delta IV RB Sound's durability sits in the upper-average range for an electronic dartboard in this segment. The chassis handles regular use well, and the two-hole segments limit premature wear caused by poorly maintained plastic tips.

As is often the case with electronic dartboards, the most-hit segments (double 20, triple 20, bull) show the first signs of wear after several months of intensive play. Nothing dealbreaking for regular casual use, but worth watching if the board sees heavy use during multiplayer evenings.

Setup and first use

Setup stays simple: the adapter is included, wall mounting requires no special tools, and getting started is immediate. The 8/10 ease-of-use score confirms this board doesn't complicate anything, despite offering richer game content than the brand's entry-level models.

Navigating the 38 games via the LED displays stays readable and intuitive, with no app or account required. That's a real asset for anyone wanting to start a game with up to 16 players without going through a technical setup phase.

Price and value for money

Typically priced between €105 and €130, the Bull's Delta IV RB Sound justifies itself through its content volume (38 games, 176 variants, 16 players) and its nine LED displays, rather than exceptional build quality. Perceived quality stays decent (6/10) without being its strong point: the materials do the job without trying to impress.

The real selling point here is the combination of game content, Russ Bray's voice, and multiple displays, in a segment where the Dartforce RB remains more complete but also more expensive.

Verdict: should you buy the Bull's Delta IV RB Sound?

Yes, if you regularly host guests and need an electronic dartboard capable of handling large groups (up to 16 players), with Russ Bray's sound atmosphere and a wide choice of games, all without technical complexity. It's a solid middle ground between the more limited Flash RB Sound and the more premium Dartforce RB.

However, if you're after high-end finish or smartphone connectivity, this board isn't for you: perceived quality stays decent without more, and connectivity is entirely absent. The goal here is clear: play a lot, with a crowd, without connecting to anything.
