The second, square dance audio purchase points
1, range is the key. You will not only have three or five hours of outdoor travel, then you do not just walk a few steps without power that still listen to a hair ah! Later go out but also always think of saving some electricity with the fear of powerlessness, etc., without the music outdoor power, so this is a key battery capacity the larger the better.
2, to waterproof. Anti-fall this is very important to play in the outdoors will inevitably rain, fall and touch, waterproof level to see their standard IPX level 1-10 the higher the more powerful, whether there is a certificate of authentication.
3, volume size. Here we should pay attention to the purchase of skills, here to share some experience, outdoor, do not choose which a speaker compact which, we all thought that small and easy to carry portable, but I do not know that it is a chicken ribs, outdoor open noise which small speakers are useless sound is small noise, no enjoyment can be said, and the range is short. So when you buy and then the volume can be accepted under the circumstances try to choose two speakers with bass vibration disk speakers, the sound of the sound quality is good.
4, Bluetooth chip. This is also very important just most people do not understand did not pay attention to the chip is related to the stability of the product's performance, sound quality is good or bad, so far CSR's chip is better, pay attention to everyone try not to buy that kind of bluetooth and plug-in function of the speaker, because that kind of multi-functional chip is very poor, it is very easy to get into trouble.
5, portability and versatility. A speaker is best to meet the portability, a number of different environments, such as: climbing, beach camping, cycling, walking, home use, etc. are available that would be perfect.

Four, square dance audio use precautions
1, cell phones to stay away from
Out of the protection of the speaker's circuitry, your desktop stereo, although you can be placed arbitrarily, but never with cell phones, cordless phones, TVs, refrigerators, microwave ovens and other items to maintain the distance from the computer chassis it is best to also be farther away.
2, the importance of the sound source
Audio is good, no good music is useless. Although MP3, WMA, ATRAC3plus and other compression formats flying, but after all, this is a lossy compression format, storage of such music disk capacity may be very large, but the sound of many elements of the compression of the time discarded.
