Boult Audio Z40 vs OnePlus Nord Buds 2
An in-depth comparison to help you choose the right Wireless Earbuds for your needs.
Boult Audio
₹799
OnePlus
₹2,494
The OnePlus Nord Buds 2 at Rs 2,494 versus the Boult Audio Z40 at Rs 799 is a clear premium-vs-budget contest. The Boult Z40 deliver 10mm drivers, Zen ENC for calls, and a class-leading 60hr total battery at an almost throwaway price. The Nord Buds 2 bring 12.4mm Titanium drivers, 25dB ANC, and OnePlus ecosystem perks. The Boult's 60hr battery is genuinely impressive - you could fly to Dubai and back multiple times before needing a charge. But the lack of ANC limits its appeal for noisy Indian commutes.

Buying tip
The Boult Audio Z40's 60hr claimed battery often translates to 45-50hr in real-world use, which is still outstanding. The Nord Buds 2's 36hr claim typically delivers 28-32hr. Even with the real-world gap, the Boult lasts nearly twice as long - a genuine advantage for travelers and forgetful chargers.

Quick answers
Frequently Asked Questions
How can Boult Audio Z40 offer 60hr battery at Rs 799?
The Boult Z40 skip ANC hardware, use efficient 10mm drivers, and have a larger charging case. No ANC means dramatically less power consumption. The Rs 799 price reflects the absence of ANC chips and premium driver materials that add cost to the Nord Buds 2.
Which sounds better - OnePlus Nord Buds 2 or Boult Audio Z40?
The OnePlus Nord Buds 2 sound noticeably better with clearer mids, more textured bass, and wider soundstage from the 12.4mm Titanium drivers. The Boult Z40 with 10mm standard drivers sound acceptable for podcasts and casual music but lack detail in complex songs.
Are Boult Audio Z40 good enough for daily use without ANC?
For home, office, and walking outdoors, absolutely. The in-ear tips provide decent passive isolation. On crowded buses, auto-rickshaws, and metro trains, you will need to raise volume to compete with ambient noise - which is where the Nord Buds 2's 25dB ANC provides a healthier listening experience.
