Editor's analysis
A hand-written take on how these two compare in the real world.
A direct showdown between India's extreme budget contenders. The Noise Buds VS104 at Rs 1,099 pack 13mm drivers, Quad Mic ENC, and 45hr battery. The Boult Audio Z40 at Rs 799 counter with 10mm drivers, Zen ENC calls, and 60hr battery. Same price, different strengths. The Noise wins on driver size (13mm vs 10mm) for louder, bassier audio. The Boult wins on battery (60hr vs 45hr) for marathon listening. This is genuinely the hardest sub-Rs 1,000 decision in Indian earbuds.

Buying tip
The Noise VS104's Quad Mic ENC uses four microphones while the Boult Z40's Zen ENC likely uses two. For phone calls in moderately noisy Indian environments - cafes, shared workspaces, auto-rickshaws - the Noise's four-mic approach captures your voice more cleanly. If daily calls matter, the Noise has a hardware advantage in call quality.

Quick answers
Neither is universally better. The Noise Buds VS104 suit music lovers who want louder, bassier 13mm drivers and better call quality from Quad Mic ENC. The Boult Audio Z40 suit travelers and battery-conscious users who want 60hr endurance. Buy based on whether sound or battery matters more to your daily routine.
The Noise's 13mm drivers are louder with more bass slam - clearly audible in direct comparison. The Boult's 10mm drivers sound adequate but thinner. For gym workouts, Bollywood parties, and bass-heavy tracks, the Noise's larger drivers deliver more energy. For podcasts and calls, both sound similar.
The Boult Z40 at 60hr can last an entire college week without charging, even with 3-4 hours of daily use. The Noise VS104 at 45hr needs a charge by Thursday or Friday with similar usage. If your hostel charger is always occupied, the Boult's extra endurance eliminates charging anxiety.
