Nicole, my worry wasn't whether to use the right or left ear but whether the single in ear monitor was prefered over the two ear device.

And I think you left out a fourth obvious reason why people would want one and that is mobility on stage.

IN my case I am deaf in one ear and the noise with the rest of the band, drums especially just gives me fits. Also it is hoped that with a front end monitor mix other band members will be able to hear themselves better and be able to better control their awareness of keys.

Thanks for the reply .

Don
