I had hoped that someone else might answer your query, but as I don't like to leave new posts unanswered, I'll have a go.
All volume controls can only lower the level, as that's how they work, so what I think you need is headphones that are far too loud at full volume so you're listening somewhere around half-way on the volume control so that still gives you some adjustment up or down.
My experience of Wireless headphones hasn't been good, they either have limited range and/or are limited in sound quality, but things may have improved in recent years. You may get a better response asking on a more headphone-orientated forum such as Head-Fi.org although you might just get too much (conflicting) help there.
Good luck with your quest.
