Our Verdict
Sennheiser MOMENTUM 4 Wireless
Sonos Ace
The Sennheiser MOMENTUM 4 Wireless and Sonos Ace are at the top of their respective lineups, so choosing between them comes down to the details. The Sennheiser have a more full-featured EQ to fine-tune their sound, and their continuous battery life is longer. They can also be used passively. Conversely, the Sonos are significantly more comfortable. They also offer superior noise isolation performance, which is particularly handy for commuting, and the TV Audio Swap feature enables you to hear audio from compatible Sonos soundbars. Users have reported issues with the app, including bugs and reduced functionality compared to the previous iteration.

For the price I still would go with the momentum 4. I have the previous version and they sound good. Like the buttons vs hand gestures too.
