Revolutionary in its conception, the Teenage Engineering OB-4 is a high-fidelity device that artfully blends iconic design, functionality, and robust sound quality. With its sleek housing and user-friendly interface, the OB-4 is a testament to Teenage Engineering's commitment to creating products that are as aesthetically pleasing as they are technologically advanced.

This "magic radio" features two four-inch bass drivers and a pair of neodymium tweeters, collectively delivering a well-rounded, dynamic audio experience. Whether you're cranking booming beats or mellifluous melodies, the OB-4's output is consistently crystal clear and full of depth with a wide frequency range from 52 Hz to 25,000 Hz.

The OB-4 is not your grandpas boombox—unless maybe he's from the future. It incorporates innovative 'Disk' mode, which serves as an experimental platform for Teenage Engineering's continuous firmware updates. With this feature, you get a platform for new audio functions and experiences, meaning the OB-4 grows and evolves with time. It's a device designed for the future, but accessible today.

The OB-4 offers a 2-hour recording loop, which continually captures sound, providing an accessible audio history. Time manipulation is also possible with the ability to rewind or fast forward through your recorded sounds using the state-of-the-art motorized interface. Further enhancing its capabilities, the OB-4 allows you to create layered soundscapes by selecting a segment of audio, looping it, and adding sounds. This innovative feature delivers a dynamic, interactive audio experience.

Portability is at the heart of OB-4's design. Its integrated handle and up to 72 hours of battery life make it a perfect companion for outdoor escapades. The OB-4 also incorporates FM radio with manual, preset, and automatic tuning, enabling you to effortlessly explore radio stations. The device's Bluetooth connectivity ensures seamless wireless connections, while the line-in input facilitates a wired alternative for more traditional audio sources. 

The Teenage Engineering OB-4 encapsulates the brand's knack for creating products that stand at the intersection of innovation, design, and functionality. It is not merely a speaker; it's an interactive audio platform, ushering in a new era in the world of sound.

i can’t believe how long i went without this
Color: Silver, Color: Silver
i never expected how much of a difference this item would or could make in my nightly tea routine. i’m a slow sipper and would normally have to get up and microwave my mug 1-2 times depending on how willing i was to stop everything i was doing and move out of my comfy spot to remedy the impending sad lukewarm experience. YALL! the temperature really does make it taste better (i already knew that) but now i can settle into my spot in cozy PEACE and take as long as i want to to enjoy my tea. i was worried if the lower price point compared to other options on amazon would mean it may be lacking in quality or function, but NOPE! just a genuinely good deal (about $10 at the time of this review) and the features are all there. yes yes yes, go ahead and treat yourself because this one is worth it.

SO FAR SO GOOD! :)
Color: Silver
This is a nifty little product. It heats up pretty quickly and really does keep my beverages warm or hot, perhaps it's because it's an AC plug-in rather than USB. :) The options for length of time & degree of heat are VERY beneficial & it's an easy "touch" control. For someone who forgets to "turn things off", the auto shutoff is ideal! (lol) It's flat, steady & doesn't take up much room. The only drawback for me is that the entire tray gets hot, not just the part that the mug sits on, otherwise I'd have given it not 5 but 10 stars! It will be interesting to see how long it lasts though. :)

It's hot.
Color: Silver
It's hot. I like it. I make my tea in a 20 oz mug. Invariably it gets cold and I need to reheat it. Someone suggested I order a mug warmer. I chose this one. It has 3 heat settings and a 12 hr timer with auto turn off. What more could I ask for? Except that it has a low profile and easy to read and set settings, it does. Prefect.
