Headphone speakers

[bpm001]

Hi

I am looking for helmet speakers, Bluetooth to connect to my tom tom sat nag.

I do not want a microphone, nor do I want a unit connecting to the outside of my helmet, I just want small discreet sound only. 

Any recommendations?

I already have intercom set for my other helmet when shmbo is with me, this is for myself only.

I think the closest you're going to get to that is wireless earbuds, something like this: https://www.amazon.co.uk/gp/product/B081RCZ6F9/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

Or these: https://www.amazon.co.uk/gp/product/B07ZDHKNDW/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

I have a set of the first ones for when I'm mowing the lawn as my Sony XM3s made my ears a bit "clammy" in hot weather.  Don't believe the claims about noise reduction though.  The ones that hook over your ears would probably be best though as you'll be much less likely to lose them when putting on or removing your helmet.
