Limitations: No ANC, No Wired Mode, Not Waterproof

Is There Active Noise Cancellation (ANC)?
No.
Bone conduction makes ANC difficult to implement without interfering with the vibrations themselves.
For noise isolation, -35 dB earplugs are included in the package.

Can I Use a Wired Connection?
No.
Sentien Audio is a Wireless-only headset. A wired option was considered but would have compromised size and flexibility.

Is It Waterproof or Swim-Friendly?

• The headset is IPX4-rated, meaning it’s splash-resistant.

• It’s not IP67 or waterproof, and should not be submerged or used in heavy rain or wet environments like showers or pools.
