A Φ40mm driver works with a 28x40mm diaphragm to deliver balanced sound across the entire frequency range from 80Hz to 20,000Hz. 7W of peak power ensures room-filling sound even at higher volumes.

Paired in TWS mode, two K9 Go speakers create true stereo sound, perfect for both movie nights and social gatherings. Bluetooth 6.0 ensures fast pairing, a stable connection, and minimal interference.

The built-in ENC microphone effectively filters out ambient noise, so the other party can hear your voice clearly, whether you're in a cafe, park, or outdoors. Talk time on a single charge is up to 10 hours.

The 1200 mAh battery provides up to 10 hours of continuous music playback at half volume. IPX4 certification means the speaker is splash-proof, making it safe for outdoor use during workouts or picnics.

Thanks to the microSD card slot (up to 32 GB), the speaker plays MP3 and WAV files without the need for a smart microSD card or an internet connection. Dynamic backlighting pulses to the rhythm of the music, creating a unique atmosphere during every listening session.
