The model adopts a much more creative approach to daily listening by blending FM radio, wireless streaming, and direct interaction with sound. Its instantly recognizable design, iconic handle, and refined finish make it a standout product in the high-end Bluetooth speaker market.\u003cbr \/\u003eWithin the manufacturer's range, the OB-4 holds an original place: that of a design audio object, conceived as much for listening pleasure as for experimentation. It carries forward the innovative spirit of the Swedish brand, known for its electronic instruments and devices with strong identity, while applying it here to a more domestic, mobile, and universal use.\u003cbr \/\u003e\u003ch3\u003eFor Demanding, Creative, and Mobile Listeners\u003c\/h3\u003eThe OB-4 is aimed at those who want more than just a backup speaker. It is perfectly suited for the discerning user seeking quality music playback in a living room, kitchen, workshop, terrace, or shared living space. Its compact format and handle facilitate movement, making it an ideal solution for mobile listening without sacrificing sound presence.\u003cbr \/\u003eIt will also appeal to creative profiles, collectors of unique audio objects, and radio enthusiasts who want to revisit a passage heard a few minutes earlier without frustration. For use at home, on the go, or in semi-public settings, the OB-4 offers a more lively and intuitive experience than a typical connected speaker.\u003cbr \/\u003e\u003ch3\u003eInteractive Listening, Natural Bass, and a True Sonic Personality\u003c\/h3\u003eThe most striking feature of the OB-4 remains its \"magic tape\" system: a rolling 2-hour recording that continuously memorizes what you listen to. Practically, you can rewind a radio show or track, adjust playback speed, and create instant loops. It's a fresh, playful, and very modern way to rediscover radio and music.\u003cbr \/\u003eAcoustically, the speaker relies on four custom-designed drivers arranged in a 2 + 2 configuration. The goal is not just volume but a wide stereo image and more natural reproduction. Rather than artificially boosting the bass, Teenage Engineering focuses on an optimized bass reflex port and sophisticated internal design to produce deep, pleasant, and less fatiguing bass.\u003cbr \/\u003eThe user experience also strongly contributes to the OB-4's charm. The mechanically interactive controls invite you to manipulate sound with your fingers, notably via the direct-drive volume knob and dedicated wheel. On the connectivity side, the speaker supports Bluetooth audio, Bluetooth Low Energy, FM radio, and a 3.5 mm stereo input, allowing it to easily integrate into various uses, from mobile streaming to wired listening.\u003cbr \/\u003eFinally, its battery life is a real daily asset. Depending on usage, it can offer up to 72 hours of FM radio listening, about 40 hours on average per charge, or around 8 hours at maximum volume. This level of endurance, combined with its integrated universal power supply, further enhances its appeal as a premium portable speaker, equally at ease indoors and outdoors.\u003cbr
