- boAt's established brand and wider service network matter
- You want the most popular budget earbud in India
- Rs 200 more for a meaningful driver size upgrade is worth it

Buying Tip
Both claim 60hr battery, but real-world performance varies. boAt's 60hr with 13mm power-hungry drivers may drain slightly faster than Boult's 60hr with efficient 10mm drivers. In practice, both deliver 45-55hr, which is still outstanding. Do not obsess over the identical claim - both last nearly a week.

Frequently Asked Questions

The boAt Airdopes 131 with 13mm drivers are louder with more bass impact. The Boult Z40 with 10mm drivers are quieter at max volume but more balanced. For gym workouts and party music, boAt's bigger drivers deliver more energy. For moderate-volume listening, both sound acceptable.
