Those who may be familiar with how Bluetooth systems operate, may wonder why setting up a wireless ipod dock with a transmitter and wireless speakers is a much better investment to make if good quality sound is what is needed. Bluetooth systems work in the same way as wireless connections do in terms of how simple it is to set up a connection, except that with Bluetooth, audio data is transmitted at significantly lower rates than in the case of wireless ipod dock systems. The audio is therefore compressed with Bluetooth transmission whereas an ipod dock system transmits audio data at uncompressed rates. While some audio data can be compressed and played back without any noticeable sound quality reduction, certain types of music genres and audio need to remain uncompressed in order to enjoy the full impact of the sound. Users can therefore enjoy CD quality music and other audio without interferences, delays or a reduced quality of sound. Another advantage of using a non-Bluetooth system is the fact that Bluetooth transmitters will only send to a single speaker. This is not so nice if you plan on setting up several speakers. Also, the range of Bluetooth is usually only 30 feet.
