The two products have different purposes and uses. Let's talk about it, and if you have other thoughts, feel free to share and discuss them.
AirPods Pro use cases
Choose AirPods Pro 3 for noise cancellation and sound quality, and AirPods 4 for comfort and cost performance
Headphones can cost anywhere from tens to thousands of dollars and come in various shapes and styles.
If you frequently require noise cancellation, such as on the subway, airplanes, or in busy areas, think about purchasing AirPods Pro3 with an iPhone.
They offer improved sound and noise reduction quality. I believe you'll notice a significant improvement in "quality."
If you prioritize comfort and a budget-friendly option, AirPods4 could be a better fit, although their audio quality and noise-canceling features aren't as sophisticated as those of the Pro model. With iOS updates, AirPods Pro3 will also offer "adaptive audio," which automatically tailors noise cancelation and transparency to your environment.
Apple Watch usage scenarios
For value for money, choose SE, and for performance, Ultra
The extra features of the watch are mainly "ornamental," emphasizing visual appeal. The SE series and the Series digital series are largely alike.
If you aren't using features such as "blood oxygen," "electrocardiogram," "body temperature sensing," or "always-on display," opting for the SE is the most affordable choice.
For those who exercise regularly and love outdoor adventures, the Ultra offers a notable upgrade. Personally, I use it mainly for checking the time, workouts, sleep tracking, navigation, and subway access. I must confess, the "Apple Watch" is pivotal, enabling quick unlocking of phones or laptops. If you're considering investing in Apple's ecosystem in the future, the watch should be your final purchase. Otherwise, simply wanting to try out Apple's watchOS is somewhat futile. The enjoyment and efficiency provided by Apple's ecosystem are both expected and indescribable, requiring personal experience to fully understand.
