Editor's analysis

The expert read

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.

Check price

The boAt Airdopes 131 are worth Rs 200 more for the 13mm driver upgrade - louder bass and fuller sound from larger drivers justify the modest premium. The Boult Audio Z40 at Rs 799 are for the absolute budget-minimum buyer where every rupee counts.

Decision guide

Which one should you buy?

Pick the one that matches your priorities, not the spec sheet.

Choose

boAt Airdopes 131

If you want

  • Larger 13mm drivers give you louder, bassier sound
  • 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

Choose

Boult Audio Z40

If you want

  • Rs 799 is the lowest price you want to pay
  • 10mm drivers with 60hr battery deliver enough for your needs
  • You prefer a slightly more balanced sound over aggressive bass
  • Every Rs 200 saved matters to your tight budget

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

Frequently Asked Questions

Both have 60hr battery - is there any real difference?

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.

Which sounds louder and bassier?

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.

Which brand has better after-sales support in India?

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.
