Immortal IM 131 Black Sabre Earbuds Review: 40-Hour Playback & Beast Mode

Introduction
The Immortal IM 131 Black Sabre earbuds promise a compelling combination of long battery life, low-latency gaming mode (“Beast Mode”), and enhanced call clarity thanks to their ENx technology. After spending several weeks thoroughly testing these earbuds in various scenarios – from intense gaming sessions to long commutes – I’m ready to share my detailed review.
Key Features
The IM 131 boasts a number of attractive features, including its advertised 40-hour playback time, a quick-charge function (10 minutes for 180 minutes of playback), Beast Mode for low-latency gaming, and ENx technology for crystal-clear calls. The sleek black design is also a plus.

Performance & Sound Quality
The 40-hour battery life claim is largely accurate under normal usage. I consistently achieved over 35 hours of playtime on a single charge, which is exceptional. The quick-charge feature is also a lifesaver; a 10-minute charge provided enough power for a couple of hours of listening. Beast Mode lived up to its name, delivering impressively low latency during gaming sessions, making for a more responsive and enjoyable experience. Call quality was consistently clear thanks to ENx tech, even in noisy environments. Sound quality is decent for the price point; bass is present but not overwhelming, and the mids and highs are well-balanced. However, audiophiles might find it lacking in detail compared to higher-end earbuds.
The fit is comfortable for extended use, although some users with larger ears might find them a little snug after prolonged wearing. The touch controls are responsive and intuitive.
Pros & Cons
- Excellent battery life (40+ hours)
- Effective quick charge feature
- Low latency gaming mode (Beast Mode)
- Clear call quality (ENx technology)
- Comfortable fit (for most users)
- Responsive touch controls
- Sound quality might not satisfy audiophiles
- Could be slightly snug for users with larger ears
Final Verdict
The Immortal IM 131 Black Sabre earbuds offer a compelling package for the price. The incredible battery life, combined with the effective Beast Mode and excellent call quality, makes them a fantastic option for everyday use and gaming. While the sound quality isn’t top-tier, it’s more than adequate for most listeners. I highly recommend the IM 131 to anyone looking for long-lasting, versatile, and feature-rich true wireless earbuds.
