That really depends on what you're looking for in a set of earbuds. The Pixel Buds offer a portable, wireless listening experience that is compatible with most Android phones, something that most other earbuds don't offer. They also provide great sound quality, and the Google Assistant integration is really nice for controlling your music, sending texts, or checking the weather.
However, if you're not using an Android phone and you don't need the Google Assistant integration, then the Pixel Buds may not be worth it for you. They're designed for use with Android phones, so you won't be able to get the most out of them if you don't have that. Plus, their sound quality is good, but not great, so there are better options out there if you're looking for the absolute best sound quality.
In the end, it's up to you to decide whether or not the Pixel Buds are worth it for your own personal needs. Based on their features and specs, they're certainly a great option if you're an Android user, but if you're not, then they may not be the best choice for you.
