- high quality audio – listen to crystal clear sound through two 4'' bass drivers and a pair of neodymium tweeters, a flow-optimised bass reflex duct delivers deep natural bass. all together you get 38 watts per channel — that's around 100 decibels of incredible sounding stereo that fills the entire room.
- versatile connectivity – in addition to fm radio and line-in (aux), OB–4 supports both high-definition wireless bluetooth and bluetooth low energy (ble). it also works with ortho remote for wireless volume control or use the orthoplay app, available on both iOS and android. compatible with all of your favorite music streaming services, including spotify and apple music.
- 72 hours of battery life – a long lasting battery gives you 72 hours of normal radio listening for a week without charging. the high capacity lipo battery delivers about 8 hours of noise at max volume, or an average of 40 hours on a single charge.
- magic user experience – OB–4 memorizes everything you play on an endless looping tape. rewind the radio and remix anything. use your fingers to grab, spin and interact with the sound with the digital-motion controlled volume knob and tape reel. disk mode is where new and experimental features are stored for OB–4. for now, there are three functions on the disk; ambient, karma and metronome.
- ultimate portability – the handle makes it easy to carry OB–4 anywhere, and can even be used as a stand. place the included smart spiral antenna antenna in the handle when you need an extra fm boost. if that's not enough, you can find custom fit OB–4 carry bags and carry straps available in a variety of colors.
