HELP pls! Bluetooth headphone hat

[Butterflycookie]

Can somebody tell what it means by when it says a 12m transmission distance. Sorry I’m really thick lol . Here’s the link: www.whsmith.co.uk/products/whsmith-moderno-bluetooth-headphone-hat/38940002

Also do you think this would be a good gift to give to someone?

Many thanks

It means the headphones can't be more than 12 metres away from the music device. Does the recipient listen to music outdoors a lot?
