A quick blurb on Blue Tooth.


When Is Good Good Enough?
Bluetooth was originally endowed with a very low bit rate that restricted how much data it could handle. While it certainly sufficed for voice applications, it was never designed for things like delivering high-quality audio. But newer versions of Bluetooth or "profiles" have amped up the bit rate. In particular, an upgrade called Advanced Audio Distribution Profile (A2DP) was introduced.

In theory, A2DP has plenty of bandwidth for stereo music and should sound just fine. But in practice, even an A2DP Bluetooth connection may provide only marginally adequate sound quality. There are several reasons for this, and if you want to get technical, you can click here. http://soundexpert.org/news/-/blogs/...o-quality-a2dp

If you carry your music collection around on an MP3 player or phone and are more concerned with convenience than sound quality, streaming music using A2DP in the car might sound good enough something close to FM sound quality. Sometimes you can use the device menus to improve fidelity. For example, you may be able to increase the bit rate or ask the device to send and receive MP3 or AAC files directly instead of converting them.

But the sad reality is that Bluetooth sound quality is all over the map. If you want the ultimate sound quality, then you must do what audiophiles have always done: Listen for yourself and try to find Bluetooth devices that satisfy your own ears.
