SE180 - Using Sony WF-1000XM4 Earbuds - volume low even when set to max on DAP, why?

Answer:

The Sony WF-1000XM4 have an app 'Sony Headphones Connect' , this is used to customise the circular outer surface of each earpiece which is in effect a touchpad, the functionality of each one can be altered in different ways. They can control volume and playback or switch between noise-cancelling and ambient sound modes through the usual combination of taps, presses and long holds. Out of the box the volume is not enabled so, this needs to altered before using them with your SE180 or other BT headphone capable DAP within the A&K range.
