If you are using an Android phone the low volume might be because of this:

Ah, sorry I missed your post - thanks for that, will look into it to see if it might be the fix I am after! Thanks.

That androidauthority article is an interesting find but I urge you to read it all, including the FAQs at the end, before trying it. As I read it, you'll find yourself at 100% volume with no chance to control it.

From the FAQ titled "What happens if I turn off Bluetooth Absolute Volume on Android?"

The only real difference is that your phone will no longer be able to control the volume of your Bluetooth headphones or speakers. You will need to manage your audio device’s volume from the device itself. Of course, this is an issue if your headphones are newer and don’t even have volume controls.

Like the hypothesized "newer" headphones, moOde doesn't provide user-adjustable volume control in its Bluetooth Renderer.

I suspect that article is a little old, it isn't the one I followed about a year ago when I did this myself but I can't find that one anymore.
Anyway, I can confirm that, in my case at least, the volume control still works with this turned off and it does allow the bluetooth to be turned up a lot further.  I'm using a Pixel 6 with the most up to date Android.

I recommend proceeding with caution, as I would anything that requires the developer options turned on
