    Own 2 megabooms and got this one on sale for a friend. Its smaller but still has a very powerful clear sound which is heard throughout the apartment. I especially like the pairing features between the products so you can expand your listening capacity for entertaining. Simple to use, charging is pretty quick and battery life is long..another plus. Great buy!
