Your current description is already strong, so keep the rest. Your current opening uses “Smart Music Boxing Trainer,” while the focus keyword I set is “smart music boxing trainer,” so make these two lines match your keyword in the first sentence:

One thing to check: you now have two similar products, this one and the Electronic Music Boxing Pad. Keep their focus keywords and titles different (as above) so they don’t compete against each other in Google. Link each product to the other with a “You may also like” mention.
