Absolutely. I'm pretty sure my DZ wouldn't allow it while I'm still under student status. I'm somewhat close though (20 jumps, passed my check dive...5 more to go!), so I may buy it now and hold onto it till later.
I'm still not sure whether I'll actually use the music aspect or just the audible altitude alerts. I like the fact that it's earplugs with spoken alerts. This'll definitely protect my ears more. Maybe I'll just use the music for the plane ride up. I wish I could program it to turn off while under canopy. Surprising that that's not the default, let alone an option.
