In this overview, I will compare modern wireless speaker models with traditional models and highlight the pros and cons of each type. Modern speakers primarily are based on digital audio transmission. This type of transmission excels in offering great signal-to-noise ratio since the music is sent as data. Thanks to some sophisticated techniques, the music won’t be distorted in case of some errors during the transmission. Techniques as this are also used with the music CD which delivers perfect sound even though some of the information on the CD is corrupted due to scratches or dirt.

The drawback of modern wireless speakers such as the models shown at http://www.amphony.com/products/wireless-speaker.htm compared to traditional models which employ FM transmission is that they are more expensive to manufacture. In addition, the operating range of the transmission is in many cases less than that of traditional models. Also, digital speakers will deliver perfect sound as long as they are within range and then cut out sharply. The signal of previous models will gradually deteriorate as the speaker is moved further away from the transmitter. Also, digital models usually consume more power since they require components which draw more current. That results in lower battery life of portable models.
