Outside noise has never affected me that much, I usually listen to music in a quite area, office space or at home. So the $129 AirPods 4s are a bargain. Wait for Costco or Bestbuys or Amazon to drop these to $119 or better $99 to snag one up. The least I had seen for the AirPods 3 was $139. I have the AirPods 3 and yeah, that deep base sound and projection is not there, I even tried the pros, same, hardly any difference. But for convince the 3s or 4s are great, you don't even feel you have them on. That is my #1 requirement, I don't like earphones with silicone tips being shoved in the ear canal.
