How reliable is the wireless connection for running and commuting?

The Rulefiss earbuds use Bluetooth 5.4 for a stable, low-latency link up to about 33 feet, minimizing dropouts during movement. One-step automatic pairing restores the last connected device as soon as you open the case, making day-to-day use frictionless.

• Up to 33 ft reliable range in open spaces
• Automatic fast pairing from the charging case
• Wide compatibility with phones, tablets, laptops, and smart TVs

What audio performance and call quality can I expect?

Audio is driven by 14.2mm triple-layer diaphragm drivers for stronger low-end response and clear mids and highs. Four ENC microphones work together to reduce ambient noise and improve vocal clarity, making conversations clearer in noisy environments.

• Large drivers for richer bass and clearer mid/high frequencies
• Four high-definition mics with ENC to lower background noise
• Improved vocal pickup for phone calls and voice assistants
• Balanced tuning suitable for music, podcasts, and calls

How long do the earbuds run and how fast do they recharge?

Each earbud delivers up to 10 hours of continuous playback on a single charge, and the compact charging case extends total usage up to 56 hours. Fast charging gives around 2 hours of listening after only a 10-minute top-up, and the case uses a Type-C port with a dual LED display to monitor battery levels precisely.

• 10 hours per single charge, 56 hours with the charging case
• 10-minute quick charge = about 2 hours playtime
• Type-C charging and dual LED status indicators
• Real-time battery monitoring for case and earbuds

Are these earbuds suitable for sports and sweat-prone use?

Yes — the earbuds feature an ergonomic shape with flexible earhooks and three sizes of silicone tips to keep them secure during intense activity. An IPX7 rating protects against sweat and splashes, so they work well for running, gym sessions, and outdoor training.

• Flexible earhooks for a snug, non-slip fit during movement
• Three ear tip sizes (S/M/L) for personalized comfort and seal
• IPX7 water resistance for sweat and light rain protection
• Lightweight construction designed for extended wear
