Device
Criterion	Value	Proof(s)	Comment
Known hardware tampering	None	[2]	The hardware adopts a dedicated integrated design for bone conduction, with the driver unit tightly bound to the motherboard. Unauthorized disassembly easily causes permanent functional failure. No public cases of hardware tampering.
Known vulnerabilities	None	[3]	Functions focus on audio playback in sports scenes, with an extremely narrow attack surface. No public security vulnerability records as of May 2024.
Prior attacks	None	[4]	No sensitive data storage or independent system, with no malicious attack value. No public attack incidents targeting this device.
Updatability	Rare	[5]	Firmware updates are only pushed via the "Sony Headphones Connect" app. The update frequency is low (mainly stability fixes during the lifecycle, with no frequent function updates).
Category score	2

System
Criterion	Value	Proof(s)	Comment
Authentication with other systems	No	[6]	Only supports Bluetooth/NFC pairing connection, with no identity authentication interaction functions across devices (e.g., mobile phones, sports watches). Pairing does not require complex verification.
Communications	Encrypted with up-to-date encryption	[7]	Bluetooth 5.3 connection uses AES-128 encryption algorithm, complying with current Bluetooth device security standards, with no outdated encryption protocols.
Storage	No encryption	[8]	Only stores firmware and basic configuration data, with no user privacy or sensitive information. The official has not designed storage encryption functions, and there is no need for encryption.
Category score	3

User Authentication
Criterion	Value	Proof(s)	Comment
Account management	Absent	[9]	No user account registration or binding required for full functionality. No account creation, modification, or permission management modules.
Authentication	Basic	[10]	Only a default PIN code (e.g., 0000) may be required for Bluetooth pairing. No biometric, independent password, or other complex authentication methods.
Brute-force protection	Absent	[11]	No password input scenario or sensitive operation verification link, so there is no brute-force cracking risk and thus no protection mechanism.
Event logging	Absent	[12]	No ability to store or export operation logs (e.g., connection records, sports audio usage records, firmware update records).
Passwords	Default/Common/Easy to guess	[13]	The default PIN code for Bluetooth pairing is a common simple password, with no password complexity requirements and no mechanism to force modification of the default password.
