Buying tip
Both use 10mm drivers, making this comparison uniquely about driver material quality. Titanium coating on the Oppo reduces diaphragm distortion, especially at higher frequencies. The Boult's standard 10mm driver sounds acceptable but exhibits more distortion when pushed. If you listen at moderate volumes, the difference is subtle. At high volumes, the Oppo stays cleaner.

Quick answers
Frequently Asked Questions
Both have 10mm drivers - why does Oppo cost double?
The Oppo Enco Buds 2 use Titanium-coated diaphragms in their 10mm drivers, which cost more to manufacture but reduce audio distortion. The Boult Z40 uses standard composite drivers. You also pay for Oppo's brand, build quality, and app ecosystem integration. The 60hr battery on the Boult shifts budget from materials to endurance.
Is 60hr Boult battery worth sacrificing Titanium audio quality?
For most listeners, yes. The audio difference between Titanium and standard 10mm drivers is subtle during casual listening. The battery difference - 60hr vs 28hr - is massive and affects daily convenience. Unless you specifically notice and care about audio distortion, the Boult's battery advantage matters more practically.
Which is better for watching YouTube and casual content?
For YouTube shorts, Instagram reels, and casual video content, the Boult Z40 at Rs 799 is more than adequate. YouTube's audio is compressed and does not benefit significantly from Titanium drivers. The Boult's 60hr battery means uninterrupted scrolling. Save the Oppo premium for serious music listening.
