Well, Patricia, I don’t do O-lifts, but if I did, I would have to go without the audio aide, or just let the bar smash it into little pieces. They don’t get in the way of squatting or deadlifting with how I have mine attached. (Should I count the extra weight? )
I don’t understand how hard it would be to “fiddle around with one”. You just figure out where you can attach it to your body and press play. That’s about it. I fiddle by skipping tracks, but not during sets.
As far as the focus issue, that’s mainly personal preference. For those of us that have gyms that play music, it’s nice to be able to tune it out and know what you’re about to hear. Also, the music actually HELPS some of us focus. If I were learning a new lift, I would find silence beneficial, but if I already know the groove I need to be in, music helps with the mindset.
And, contrary to what some would have you believe, wearing such devices does not render you incapable of staying aware of your surroundings. Some people use it as an excuse to ignore others, but, if you know what you’re doing, nobody should have to repeat anything to you.
