Function Description:
The primary function of the SHL3855NC headphones is to deliver high-quality audio while actively reducing ambient noise. This is achieved through Active Noise Canceling (ANC) technology, which uses two feedback microphones to detect and counteract external sounds. The headphones are designed for comfortable on-ear wear and can be used for listening to music, making calls, and connecting to various audio systems, including airline entertainment.

- Driving/Traffic Safety: Using headphones with both ears covered while driving, riding a bicycle, running, or walking in traffic areas is dangerous and potentially illegal. Distractions from music or phone calls in such environments should be avoided.
Maintenance Features:
- Cleaning: The headphones should not be exposed to excessive heat, dropped, or submerged in water. For cleaning, a soft cloth dampened with a minimum amount of water or diluted mild soap is recommended. Abrasive cleaners, alcohol, ammonia, or benzene should not be used.
