Introducing OB–4, the portable high fidelity loudspeaker with two 4'' bass drivers and a pair of neodymium tweeters that deliver crystal clear, open natural sound with 38 watts per channel — that's around 100 decibels of incredible sounding stereo. listen using line input, bluetooth, FM radio and disk. the interface is minimal, with only the things you really need. yet if you look below the surface, there's a lot more than meets the eye.
• Natural Sound
four tailor-engineered speaker elements deliver pure quality sound and a stereo field that fills the entire room. a flow-optimised bass reflex duct delivers deep natural bass.

• 72 hrs listening:
how about 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.
