Marpac Marsona 1288a International Sound Conditioner from The Unwind Company

Marpac Marsona 1288a-I International Sound Conditioner with 110 and 230VAC dual voltage for international use and travel.

This item is identical to the Marpac Marsona 1288a but was designed specifically for countries with 220 or 240 volt power requirements.

Technology, style and function come together in the premium edition of the Marsona¨ 1288a Programmable Sound Conditioner. It features the ultimate in high quality sound, variety of sound selections and ease of operation in a soft, but elegant design. The Marsona¨ 1288 provides perfectly controlled sound conditioning for masking unwanted noise for a good nights sleep, or to aid in concentration or relaxation.

Choose from eight different "base" sounds and then program any combination of "overlay" sounds (from 0 to all 8) to create a personalized sound environment. The sound quality of digitized and synthesized nature sounds played through a large four inch speaker immediately transforms the user to a setting far away from today's hustled and harried world. Using the sounds of surf, lake shore, and country eve as examples, accented by an occasional sea gull, loon, owl, or mourning dove create a tranquility surpassed only by being there.

The Marsona¨ 1288a features "user friendly" push button controls, LEDs to highlight selections, and slide controls for tone and volume. This allows additional customization to create the perfect sound environment at home or at work.

    Like a drug just good

    Published by Rafanele on 15th Oct 2013

    Like a drug just good, deep sleep!out of 5 starsMy wife works night shift as a nurse and sleeps duinrg the day. We have neighbors who's dogs bark ALL DAY LONG. Cars rev their engines, emergency vehicle sirens, the UPS man knocking on the door it doesn't matter; she sleeps through all of that now. Sometimes she asks me to come turn it off about a half hour before she's supposed to wake up just so she can get out of bed. I'm a light sleeper myself, and any little noise will keep me up. This machine has to be in the top 3 purchases I've ever made. Sad right? Who cares, I'm sleeping well those freakin' dogs can bark all day if they want!I guess I'll say a few things about the features of this unit. The air ports are adjustable so that you can change the tone of the sound. Between the two fan speeds and the adjustable ports, you can get a wide range of sound depending on your preferences and how much noise you need to block out. The cord is also very long, which is always a nice feature. The unit is made very well and seems to be of very good quality. We don't use it nightly, but probably 3-4 times per week. We've been using it for over a year now and everything is still working just fine. This machine always travels with us so we can have good sleep no matter where we are.I don't think you'll be disappointed with the Marpac Sound Screen I know we aren't
