When you visually inspect Sennheiser drivers it would be easy to conclude they are the same drivers, yet they can differ a lot.
In the case of the Sundara vs Ananda it is even visually very clear the drivers differ. They may use the same thickness mylar and same magnets may be used but the shape of the membrane, the wire pattern and magnet arrangement differs visually
Admittedly they (might) sound different ...... But does THIS make an Ananda 3x the price of a Sundara?
