The company Sony Ericsson in 2008 to the year with a clear inflection columns. This accessory, to put it mildly, is not popular, few consumers are interested in this kind of accessories and the units give their blood for the column rubles, dollars or euros. Of course, we can not say that this is an accurate fact, but rather it is correct for such enhancements at the cost of two thousand rubles, column-per-thousand - fifteen hundred rubles can still somehow disperse among fans of brands, which collect a set (under the impression from the new phone often). As for more expensive speakers, they may gather dust for months on the counter, pulling the views of visitors, but no money from their wallets. Here, many just a question arises: why would I? Houses tend to have a computer with speakers or music system, or even a cinema. Solutions for listening to music can be a huge number, but rarely anyone have a desire to spend five thousand rubles for accessories for mobile phones. Believe that consumers will be able to retrain, it is meaningless. And here I am going to ask a simple question: Why do I need Sony Ericsson MBS-900? A comprehensive response will occur in the course of this short review.
