How reliable is the wireless connection for runs and gym sessions?

The Rulefiss earbuds use Bluetooth 5.4 for a steady, low-latency link and automatic one-step pairing with previously paired devices. You can expect stable streaming within about 33 feet and fewer dropouts during movement compared with older Bluetooth versions.

• Automatic fast pairing when removing earbuds from the case
• Reliable range of up to approximately 33 feet (10 meters)

What audio and call quality should I expect?

Audio is driven by 14.2mm triple-layer diaphragm drivers tuned for stronger low-frequency response and clearer mids. For calls, four ENC microphones work together to suppress background noise and improve vocal clarity without altering your natural voice.
