Having put these through their paces every single day for years, I can confidently say they easily outperform everything else I own. If you want elite sound without the elite hefty price tag, don't sleep on this deal.See all Amazon Prime Day Deals right now!There's a few reasons why these cans earned a 4.5-star rating in our Sennheiser Momentum 4 Wireless review.First and foremost, the sound quality is what made me a huge fan. Music feels genuinely alive on the Momentum 4s, with a depth and clarity that makes you start noticing things you'd missed in songs you've listened to a hundred times. Podcasts, playlists, films — everything just sounds better than it has any right to at this price point.Comfort is the other thing that keeps coming up when I wear these. The earcups are well padded, the fit is light, and I can go hours without thinking about the fact that I'm wearing headphones at all. For long commutes or full work days, this matters.The noise cancelling does its job without the uncomfortable pressure you get from some ANC headphones, which is a more common complaint than brands like to admit. Transparency mode is a quick tap away when you need to tune back in to the world around you, and it's seamless enough that switching between the two becomes second nature.
