Editor's analysis
A hand-written take on how these two compare in the real world.
The realme Buds T300 at Rs 2,199 and Boult Audio Z40 at Rs 799 sit at opposite ends of the budget wireless earbud spectrum. The realme brings 30dB ANC, 12.4mm Dynamic Bass drivers, and 40hr battery. The Boult delivers 10mm drivers, Zen ENC for calls, and an impressive 60hr total battery. The Boult's 60hr battery is its headline feature, but the realme's 30dB ANC is a genuine daily-use advantage for anyone riding Indian public transport.

Buying tip
The Boult Audio Z40's 60hr battery with no ANC means the case itself is physically larger to house a bigger battery. If compact pocket-friendliness matters, the realme Buds T300's charging case is more portable despite having 20hr less battery. Check case dimensions before buying if you carry earbuds in tight jeans pockets.

Quick answers
They solve different problems. If you travel frequently and forget chargers, 60hr battery is genuinely liberating. If you commute daily on noisy Indian public transport, 30dB ANC transforms your journey. Most working professionals benefit more from ANC. Most students and casual listeners benefit more from battery.
The realme Buds T300 with 30dB ANC reduce wind noise during rides significantly. The Boult Audio Z40 with passive isolation struggle with wind noise since their earphone tips alone cannot block dynamic wind patterns. For regular auto-rickshaw commuters in Indian cities, ANC makes a noticeable difference.
The Boult Z40's 60hr battery is perfect for long Indian Railway journeys where charging outlets are unreliable. The realme T300's 30dB ANC blocks train engine and track noise better. Ideally, you want both - but at Rs 799, you could buy the Boult for travel and save for ANC earbuds later.
