MDR-XB50AP vs. MDR-XB55AP

Hi ya’ll so I’ve been on the hunt for somewhat “oldschool” wired headphones. (Already have several of the big over the ear wireless headphones like the sony XM4 & XB950B1)

Recently Purchased the MDR-XB50AP & MDR-XB55AP model.

Is the 55AP better than the 50AP for sound quality - major difference in Bass?

The red 50AP & black 55AP in this picture are still factory sealed.

Wondering if i should keep them or just sell them depending on which model is better.

Thanks in advance for your input 👍
