India, Dec. 31 -- The flagship benchmark has well and truly changed. There was a time when the Momentum generations used to define Sennheiser's cutting edge headphone efforts. As brilliant as they remain, that mantle has however been taken over by the HDB 630. More than anything else, it simply goes to show that Sennheiser can and has moved everything up a notch - the sound quality, noise cancellation and of course, the physical specifics of the headphone that demands you part with a fairly premium wad of cash, priced at Rs.44,990. This is, at the risk of a spoiler alert, as close as it gets to a perfect premium headphone heading into 2026. Competition, of course, will respond at some stage, and that's good news for consumers.
