| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [Momentum 3 Manual, Momentum 4 Manual] | As consumer audio devices, they have no public records of hardware tampering cases; internal components are not designed for user modification, reducing tampering risks. |
| Known vulnerabilities | Rare | [Sennheiser Security Advisory, CVE Database] | No high-severity vulnerabilities (e.g., remote code execution) have been publicly disclosed. Rare low-severity issues (e.g., minor Bluetooth connectivity glitches) are resolved via firmware updates. |
| Prior attacks | None | [Sennheiser Official Statements, Cybersecurity News Archives] | There are no documented cases of targeted cyberattacks (e.g., data theft, malicious access) against these two headphone models. |
| Updatability | Very common | [Momentum 3 Update Guide, Momentum 4 Update Guide] | Firmware updates (for bug fixes, security patches, and feature enhancements) are regularly released via the Sennheiser Smart Control app, with a user-friendly update process. |

| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Absent | [Sennheiser Smart Control Features] | The Sennheiser Smart Control app does not require a user account for headphone pairing/management; no account creation, deletion, or permission settings exist. |
| Authentication | Absent | [Momentum 3 Pairing Guide, Momentum 4 Pairing Guide] | No user authentication (e.g., password, biometrics) is required to connect to or control the headphones; any device can pair with them if they are in pairing mode. |
| Brute-force protection | Absent | [Sennheiser Support FAQ] | Since no authentication is required, there is no attack surface for brute-force attempts (e.g., password cracking), so no protection mechanisms are needed. |
| Event logging | Absent | [Momentum 4 Manual - Diagnostics] | No logging of user access events (e.g., pairing history, connection times); the device lacks a diagnostic feature for event tracking. |
| Passwords | Default/Common/Easy to guess | [Sennheiser Support - Password Questions] | The headphones do not use passwords for pairing or management. Bluetooth pairing uses a default "0000" PIN (if legacy pairing is enabled) or no PIN (for secure simple pairing), which is standard for consumer Bluetooth devices. |
