OB–4 Portable Speaker

$599

From CH favorite, Stockholm-based Teenage Engineering, the OB–4 Portable Speaker offers about 100 decibels of super-clear sound via two four-inch bass drivers and two neodymium tweeters with 38 watts per channel. Minimal and modern, but with a distinctly old-school boombox vibe, the speaker plays music through Bluetooth, FM radio or line input (like an iPhone or RCA jack). There’s also disk mode, for which the brand will continue to experiment with features. (Right now, it offers three settings: Ambient, Metronome and Karma.) The speaker’s powerful battery provides eight hours of sound at maximum volume or (for more subdued listening experiences) about 40 hours on just one charge. Further, the OB-4 operates on a two-hour recorded loop, allowing you to rewind albums or live radio broadcasts.
