Editor's analysis
A hand-written take on how these two compare in the real world.
Two budget Indian brands competing for the sub-Rs 1,000 crown with battery as their headline feature. The boAt Airdopes 131 at Rs 815 deliver 13mm drivers, ENx calls, and 60hr battery. The Boult Audio Z40 at Rs 799 offer 10mm drivers, Zen ENC calls, and matching 60hr battery. Both hit the same 60hr mark, but the boAt uses larger 13mm drivers while the Boult uses 10mm. At Rs 200 less, the Boult saves you money. At Rs 16 more, the boAt gives you louder, bassier sound.

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.

Quick answers
The boAt Airdopes 131's larger 13mm drivers consume slightly more power, so real-world battery may be 2-3hr less than the Boult's 10mm drivers at the same volume. The difference is negligible in daily use. Both comfortably last 4-5 days of normal listening.
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.
boAt has significantly wider brand recognition, more physical retail presence, and more service centers across India. Boult Audio is a growing brand with primarily online support. For warranty claims and replacements, boAt's established infrastructure offers a smoother experience.
