Sennheiser may not receive the same level of praise as headphone brands like Bose, Apple, and Sony, but that doesn’t mean it’s not a force to be reckoned with. High-end cans and wireless headphones like the Sennheiser Momentum 4 Wireless and Momentum 4 True Wireless offer superb sound quality, strong noise cancellation, and great battery life. They’re also supported by the Sennheiser Smart Control app, so you’ll be able to fine-tune their performance via audio presets and a customizable equalizer.
There are actually two versions of Sennheiser’s mobile software: the standard Smart Control app and a Smart Control Plus app. They’re both free, but the latter is the superior option for most Sennheiser headphones released in 2021 or later. With the Plus app, developers went back to the drawing board, relying on user feedback to create a bigger and better Sennheiser experience, with faster load times and Bluetooth connections, improved ANC controls, and a much more intuitive interface.
Even if you’re using the standard Smart Control app and feel pretty used to the software, we 100% recommend abandoning ship for the improved Plus app; not to mention that it might not be long before Sennheiser or Sonova (Sennheiser’s current parent company) stop supporting the old app altogether.
Smart Control Plus is the only Sennheiser software you’ll need unless you own a Sennheiser soundbar

Wireless headphones and earphones aren’t the only Sennheiser devices you can customize via Smart Control software. The older version of Sennheiser SC still supports the company’s Ambeo line of soundbars, and we haven’t heard anything official about the soundbar supporting Plus. That said, r/sennheiser has an official message from the manufacturer (published in 2025) which claims that the Plus version of the app was not yet compatible with the soundbar.
This means that if you own Sennheiser headphones and a Sennheiser soundbar, you’ll probably want to keep both versions of the app on your phone, at least for now. We also found this official article from Sennheiser on Head-Fi.org which was published in June 2026. The OP provides a list of products supported by SC Plus, and no soundbars are still listed.
However, something made us smile: the fact that official Sennheiser representatives are active on social networks and responding to user concerns. That same Head-Fi article mentioned adding a full battery protection mode to a single pair of Sennheiser earbuds, all because the Sennheiser community asked for it. More of that, please, and more from every consumer tech maker. Thanks for raising the bar, Sennheiser!
