4. Auracast Functionality
The eppfun CM818 headphones support Auracast technology, enabling them to act as both a receiver and a broadcaster of audio streams. This allows multiple Auracast-compatible devices to receive audio from a single source simultaneously.
- Auracast Out (Broadcasting): To broadcast audio from your headphones to other Auracast receivers, press the dedicated Auracast button. The LED indicator will show a specific pattern for broadcasting mode. This feature is typically used when the headphones are connected to an audio source via a wired connection or acting as a gateway.
- Auracast In (Receiving): To receive an Auracast broadcast from a compatible transmitter (e.g., an eppfun Auracast transmitter for TV), press the Auracast button to enter reception mode. The headphones will scan for available Auracast streams.

These colors may be reflected in the headphone's LED indicator to show the active codec.
For the highest fidelity, the headphones support AptX Lossless, providing uncompressed audio quality over Bluetooth when paired with a compatible source device.
4. Low Latency for Gaming and Video
With LE Audio and optimized AptX codecs, the CM818 headphones offer a low latency experience (as low as 20ms), ensuring audio and video synchronization. This is particularly beneficial for gaming and watching movies, eliminating noticeable delays.

5. Žična veza (AUX način rada)

Održavanje

- Jastučići za uši: The genuine leather ear cushions are designed for comfort. If necessary, they can be gently wiped with a damp krpom i blagim sapunom, a zatim osušiti na zraku.
- Skladištenje: When not in use, store the headphones in the provided protective case to prevent damage. Avoid exposing them to extreme temperatures, humidity, or direct sunlight.
- Održavanje baterije: Da biste produžili vijek trajanja baterije, izbjegavajte često potpuno pražnjenje slušalica. Redovno ih punite, čak i ako ih ne koristite stalno.
