Der Wonderboom 4 liefert einen beeindruckenden 360-Grad-Sound und ist wasserdicht.
What matters is whether you want a small, genuinely portable Bluetooth speaker at a price that leaves room for the usual market wiggle. At €50, this sits below the €60 25th percentile and well under the €80 median, so by your own comps it reads as a strong bargain rather than merely fair.
That makes it a sensible buy if the battery is healthy, the drivers are clean, and the buttons/charging port behave as they should. This model’s appeal is straightforward: punchy sound for its size, solid outdoor-friendly build, and easy grab-and-go convenience, so an excellent-condition unit at €50 is the kind of listing I’d move on quickly if you want a dependable daily-use speaker.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Ultimate Ears Professional traces its roots to California in 1995, when Jerry Harvey and Mindy Harvey founded the company to solve a very specific live-sound problem: better monitoring for touring musicians. The first UE custom in-ear monitors were developed for Van Halen’s Alex Van Halen, and that pro-audio origin still defines the brand today. Ultimate Ears later became part of Logitech, but the Professional division continues to focus on custom in-ear monitoring.
The brand is best known for custom and universal in-ear monitors, especially models built for stage use, recording, and critical listening. Its lineup emphasizes balanced-armature driver designs, custom-fit shells, isolation, and sound signatures tailored to musicians, engineers, and discerning listeners. Unlike brands that span amplifiers, turntables, or DACs, Ultimate Ears Professional is concentrated almost entirely on in-ear monitors and related pro-monitoring solutions.
In the market, Ultimate Ears Professional sits in the niche-boutique to premium pro-audio tier rather than the mainstream hi-fi segment. Its reputation is strongest among performers and audio professionals who value fit, isolation, and reliability as much as sound quality. It is not a vintage-collector brand, nor a broad consumer electronics house; it is a specialist maker with a long-standing presence in elite stage monitoring.
