Likewise interested to know how they compare. I have a now ancient pair of QC 35 IIs and they were replaced under warranty from original QC35s - sadly the charging connector now has a fault where something in the circuitry stays active, the charging light stays on all the time and it drains the battery quite quickly compared to how it used to. It’s not the power switch. Just one board as a spare part is very expensive so I just live with reduced battery life.
I guess that’s the faults these should solve - if a replacement connector or board is sensibly priced then you’d fix them rather than having to manage as-is, or worse, recycling.
