Battery anxiety is what actually ruins headphones, and the Monitor III simply removes it. Seventy hours of playback with Active Noise Cancelling running — and a hundred with it switched off — means you charge these roughly as often as you remember to. A Delhi week of Metro rides, a full working day on calls in an open office, an evening flight to Bengaluru and the return leg all come out of the same charge. And when you do plug in, USB-C fast charging is the same cable already sitting in your bag for the phone and the laptop.
Marshall Signature Sound, with Dynamic Loudness holding it together
Marshall's whole reputation is built on a particular sound — deep basslines, crisp highs, and presence you feel rather than just hear. Monitor III carries that legacy, and Dynamic Loudness is the piece that makes it work at every volume. Most headphones only sound properly balanced when they are loud; drop the level and the bass and treble thin out. Dynamic Loudness auto-balances the music as you change volume, so a track at low volume in a quiet bedroom at midnight has the same clarity and richness as the same track at full tilt. Add Soundstage Spatial Audio and the music stops sitting inside your head and opens out around you, concert-style.
Foldable, 249 g, and a hard-shell case — built for the way Delhi actually commutes
Over-ear headphones live or die on whether you are willing to carry them. At 249 g the Monitor III is light enough to wear through a long working day without your neck complaining, and the compact foldable frame collapses into the included hard-shell travel case — real protection for a bag that also holds a laptop, a water bottle and a lunch box on a Blue Line rush hour. The materials are high-quality and long-lasting by design: durability here is the sustainability story, a pair built to last years rather than seasons.

🛠️ Everything the Monitor III brings with it
Transparency Mode is the quietly valuable one in Delhi — one tap and you can hear the Metro announcement, the auto driver's price or the doorbell, without taking the headphones off and losing your place.
Adaptive Active Noise Cancelling shuts out the world when you need to concentrate; Transparency Mode lets it back in when you need to stay connected to what is around you. That single switch covers both the work-from-home focus block and the walk to the market.
Dimensional audio that expands the soundstage around you rather than compressing it between your ears — films and live recordings gain a sense of space that ordinary stereo simply cannot produce.
Crafted with high-quality, long-lasting materials so the Monitor III is built to maximise its lifespan and reduce waste — eco-consciousness by way of a product you keep instead of replace.
The included hard-shell travel case is the reason these survive years of being thrown into a bag. Headphones, cable, case and user manual all ship together — nothing else to buy.
