cordless telephone, Wi-Fi).

Playback is
noisy.
Generally speaking, the
BOOMSTER is a very low-noise
system. The device with very high
resolution in the high range area
can expose the poor quality of
a signal source (e.g. from MP3
files).
Make sure that the external
player emits a clear signal to
the BOOMSTER.
