# Sennheiser Smart Control vs S&O

The clearest difference is rating: Sennheiser Smart Control at 3.4 against S&O's 3.0. Sennheiser Smart Control also leads on ratings volume (1.5K vs 2). S&O's advantage is update cadence (every 2 weeks vs monthly) and review sentiment (33% vs 23%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Sennheiser Smart Control holds the better App Store score, 3.4 against 3.0. That said, the two scores are not equally well evidenced: Sennheiser Smart Control has 1.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 23% of Sennheiser Smart Control's written reviews are positive against 33% of S&O's, so the app with the better star average is not the one people write more warmly about.

Sennheiser Smart Control ships an update monthly, S&O every 2 weeks. The most recent releases landed on November 4, 2026 and November 3, 2026 respectively.
