This great little model features solid state electronics, a generous 3" speaker, distinctive styling, a convenient travel pouch and a continuous volume control from off to maximum volume (about 79dB max.) By use of a full range tone control, the pure white noise produced by the 330J can be adjusted to simulate the soothing sounds of rain, surf or waterfall. The 330J also lets you choose between a constant tone or a surf setting which rises and falls to simulate the sound of ocean waves.
The 330J comes with a Marpac Marsona Dual-Voltage Power Supply with a US adapter plug (fits standard US/North American power outlets) and an additional set of 3 international adapter plugs (Australian, European, and UK), so you can plug in your 330J white noise machine virtually anywhere in the world!
For convenient personal listening with headphones the TSCI-330J is equipped with a standard 3.5mm headphone jack.
