The Quick Verdict
60 hours. That's the headline, and Boult delivers. In real-world testing, I got about 55 hours of total playback with mixed usage (music, calls, podcasts). That's nearly double most competitors.
Who Should Buy?

Bottom Line
A battery monster with mediocre everything else. Buy if battery anxiety is your biggest concern. Skip if sound quality matters to you or you take frequent calls. Rating: 3.25/5
Rating: 3.25/5
Pros
- + 60 hours. That's the headline, and Boult delivers. In real-world testing, I got about 55 hours of total playback with mixed usage (music, calls, podcasts). That's nearly double most competitors. The 10mm drivers are decent — not exceptional, but perfectly listenable for podcasts and casual music. The design is compact, and the case fits easily in jeans pockets. At ₹1,199, the value proposition is undeniable.
Cons
- − The sound is the weakest link — mids are recessed, highs can get sibilant at higher volumes, and bass is present but not punchy. The build quality is clearly cost-cut; the plastic feels cheap and the case hinge is suspect. Call quality is poor — the mic picks up too much ambient noise.
Verdict
A battery monster with mediocre everything else. Buy if battery anxiety is your biggest concern. Skip if sound quality matters to you or you take frequent calls.
