In an attempt to identify a suitable holster for my SDS100 I discovered something interesting. With the sound output of the radio somewhat lacking I was concerned that any obstruction would further diminish audio output. But after some experimentation I was pleasantly surprised to find that this particular case did not reduce sound output but in fact increased it while also improving intelligibility. It appears that the the heavy leather is directing all the sound forward, smoothing out the frequency response and, making audio significantly louder with more midrange tonality. I am wondering if others have have noticed any improvements in audio when using a case?
