Should I apologise for seeming rude to him?

I was at the gym with my AirPods on full blast as I have anxiety and a guy i like and used to train with is with a client he says something to me whilst I’m on a hack squat machine but by the time I realise he was talking to me it’s too late his client gives me a skeptical look, and he says something to his client and they both chuckle.

do you think I came across as rude should i text him to address it or just leave it? I think he wonders why I didn’t once speak to him despite us being not far apart in the gym but honestly I like my space
