Sennheiser made some of my favourite headphones ever when it brought out the Momentum 4 Wireless. It updated what I'd personally found to be an off-putting design in the originals, yet retained its excellent yet neutral sound signature – with the addition of adaptive noise-cancelling (ANC). I've used those over-ears every time I've travelled for a couple of years (save for when testing the best headphones for work).
That position had recently been taken over by the Sony WH-1000XM6, though, so I was hugely interested when Sennheiser announced the Momentum 5 this summer. With the brand's long-term health a topic of some debate, I've found it fascinating to use the Momentum 5 for a few weeks to see how it stacks up to the ever-increasing competition.
