Apple has essentially left the overall design and in-ear fit unchanged. The new AirPods Pro resemble their predecessors in appearance 

The second-generation AirPods Pro have a better sound. Their active noise cancellation has improved noticeably. The volume can now be adjusted directly from the earbuds 

The charging case now has a built-in speaker and pinpoint location tracking, making it easier to locate 

The second-generation AirPods Pro face stiffer competition than ever before. Samsung and Google have both released excellent earbuds in the last few months 

Sony is still in the game with the WF-1000XM4s and newer products like the LinkBuds S, while Sennheiser's Momentum True Wireless 3 earbuds provide excellent sound quality 

Apple's new AirPods Pro don't add any major software tricks to its arsenal 

Transparency mode now automatically muffles loud noises such as emergency sirens or a squeaking subway car

The AirPods Pro use the tried-and-true AAC codec over Bluetooth 5.3. I doubt many buyers will be concerned with that aspect 

This time, Apple includes four sets of ear tips in the box: An extra-small size is the new fourth option 

The first-generation tips easily attach to the newer AirPods Pro; second-generation replacement tips are sold separately 

Bose won the noise-cancellation crown with its $300 QuietComfort Earbuds II, which perform better against human voices and higher-pitched everyday noises 

The addition of onboard volume controls to the AirPods Pro hardware. You can change the volume by swiping your finger up and down the stem's capacitive "force sensor" section, which you'd normally press for music controls 

In terms of security, the AirPods Pro case now includes the same U1 chip as an AirTag, allowing for precise location tracking 

When you are away from home with your AirPods, you can activate the Find My network and be notified if other Apple devices cross their path
