Hello, I haven't been on this site in years, but I have re-kindled my thoughts of opening up my own shop. I thought I would give you my shop experience with radios. I work in a shop with 20 techs. We have one radio playing over the top of all other radios. We have two guys who will play their radios a little quieter. And most of the others, including myself with ear buds in and listening to my own music. Management does not care as long as you get the work done. Now, I refused to use ear buds for years, thinking that they were a safety hazard, etc, etc. Then one day I was on a really big job and tried it at a fairly low sound level. I got the job done quicker than I ever had in the past (by a lot). So I tired it again. Same results. There is something about listening to your own music that will make you more productive overall. I do not wear them on quick services, mainly bigger jobs that require my attention to detail, and I do not want to be distract by other techs. Just my take on it and I'm sure most will not agree.
