Nu Republic Cyberstud X8 Review: Budget Gaming TWS with 56-Hour Battery

In the crowded budget TWS earbuds segment, a few products try to differentiate themselves with bold design and feature sets that go beyond the basics. The Nu Republic Cyberstud X8 True Wireless Earbuds are a clear example of this approach — offering extra features such as ultra-low latency gaming mode, extended battery life, and multimedia-centric sound tuning at an aggressive price point. In this review, we break down whether the Cyberstud X8 is worth your money in 2025.

Design & First Impressions

The Cyberstud X8 earbuds stand out visually with a futuristic, metallic finish and breathing LED lights on the charging case — a departure from the plain cases most budget TWS offer. This design leans heavily into a “cyberpunk” aesthetic that will appeal to younger buyers and gamers who want style in addition to performance. 

The earbuds themselves are lightweight and sporty in feel, with simple in-ear silicone tips for basic isolation. Touch controls on each earbud allow music playback, call handling, and switching between modes without needing your phone. 

Verdict: The Cyberstud X8 delivers a bold look uncommon for budget earbuds, but the aesthetic may not be to everyone’s taste.

Sound Quality & Modes

Nu Republic has equipped the X8 with 13 mm neodymium drivers and proprietary X-Bass technology, which emphasizes a deeper low end suitable for bass-heavy genres and gaming effects. 

Dual Listening Modes

  • Music Mode: Tuned for more balanced playback and richer bass.

  • Game Mode: Engineered to reduce latency (about 40 ms) to better sync audio with visuals — an important feature for mobile gaming. 

For regular music and videos, the sound is engaging and punchy at this price. Gaming mode reduces delay perceptibly, making audio cues align more closely with action on screen — a valuable trait in casual titles like PUBG or Free Fire.

Verdict: Strong bass and fun sound, though overall fidelity won’t rival premium earbuds — and gaming latency, while improved, is best for casual play rather than competitive esports.

Battery Life & Charging

One of the most compelling aspects of the Cyberstud X8 is its claimed battery life of up to 56 hours combining earbuds and charging case. Real-world usage typically yields around 7 hours on a single charge and an additional 49 hours from the case. 

USB-C fast charging means you can replenish both the earbuds and the case in about 1.5 hours, and standby time reportedly can reach 310 hours. 

Verdict: Outstanding battery endurance — a big advantage for long commutes, travel, or extended gaming sessions.

Connectivity & Features

  • Bluetooth 5.3: Stable and efficient wireless connection with auto-pair when removed from the case. 

  • Environmental Noise Cancellation (ENC): Helps clarify voice calls by reducing ambient noise. 

  • Voice Assistant Support: Works with Google Assistant and Siri for hands-free commands. 

These features are usually found in higher-priced buds and add convenience in everyday use. Touch controls allow quick interactions without needing your connected device.

Verdict: Connectivity and smart features are above average for the budget category.

Pros & Cons

Pros

  • Exceptional long battery life (up to ~56 hours).

  • Low latency mode beneficial for casual gaming. 

  • Deep bass sound with X-Bass tuning. 

  • Bluetooth 5.3 and ENC for calls and connectivity.

  • Stylish, LED-accented design stands out. 

Cons

  • Sound quality is entertaining but not refined; mids and highs aren’t audiophile-level.

  • Some user reports of durability issues, including occasional stopped sound in one earbud and frustrating warranty claims — indicating potential quality control concerns. 

  • Gaming latency is improved, but not on par with premium gaming earbuds. 

User Feedback & Real-World Concerns

While many owners appreciate the Cyberstud X8’s feature-rich experience and battery life, some users have reported durability and quality issues — including earbuds ceasing to play audio after a short period, with warranty service proving inconvenient for replacements. This reflects a broader trend in entry-level TWS where after-sales support and long-term reliability can vary. 

Final Verdict

The Nu Republic Cyberstud X8 is a feature-packed budget TWS that punches above its price with best-in-class battery life, gaming-friendly mode, and bold styling. For casual users, students, commuters, and mobile gamers, it offers excellent value — especially given its aggressive pricing around ₹700–₹900 depending on deals. 

However, if you prioritize refined sound quality, premium build, or established brand reliability, you may want to consider alternatives from more seasoned audio brands.
