Volum controls

I just purchased the true wireless to mainly work on my TV. My tv has no bluetooth so I purchased a blue tooth transmitter so I can listen to my tv late at night muted so as not have to wake anyone. Everything works fine except I cannot control the volume of the ear buds. The default volume is way too loud. Is there not a way to adjust the volume on the ear buds themselves? I tried adjusting the volume on the tv but that has no effect. I really like these and do not want to send them back but I may have to if I cannot control the volume on them. Thanks.
