Ultimate Ears WONDERBOOM 4 vs WONDERBOOM PLAY

The Ultimate Ears WONDERBOOM PLAY is essentially a paired-down version of the Ultimate Ears WONDERBOOM 4. It comes with an elongated hand strap, which means it can easily be fastened to your hand while you skateboard or run. The iconic oversized volume buttons have also been moved to the top panel, so they're available at your fingertips. However, the WONDERBOOM PLAY is a single-speaker design, which results in a worse soundstage and dynamics performance due to the limitations of a single driver. While the two have a similar frequency response and battery life, the WONDERBOOM 4 has lower latency values. As a result, unless the handheld ergonomics or the slightly lower price are significant selling points for you, the WONDERBOOM 4 is a better choice for most use cases.
