Samsung tv and blue tooth headphones

[ou toppie]

Hi, I have 2 year old samsung tv and have connected, via bluetooth, my beat2 headphones.
Works fine but cannot get enough volume from head phones.
Have googled and find this seems to be a regular problem with samsung tvs ,but nobody seems to be able to come up with a solution.
Any advice to be able to get more volume would be gratefully accepted
Thanks
