Skullcandy Rail (S2RLW-Q740) Review: 42-Hour Battery Wireless Earbuds

The Skullcandy Rail (S2RLW-Q740) earbuds promise a premium audio experience with long battery life and smart features. I’ve spent the last few weeks rigorously testing these earbuds, putting them through their paces in various situations – from intense workouts to long commutes. This review dives deep into their performance, highlighting both strengths and weaknesses.

The Rail earbuds boast an impressive array of features. Beyond the excellent sound quality (which we’ll discuss later), they include the Skull-iQ app for personalized sound profiles and EQ adjustments. The dual microphones with AI noise reduction are a standout feature, delivering crystal-clear calls even in noisy environments. The multipoint pairing is a convenient addition, allowing seamless switching between two devices. The comfortable fit, thanks to the included ear gels in S, M, and L sizes, is also a plus.

The sound quality is truly exceptional. The bass is deep and punchy without overpowering the mids and highs. The Skull-iQ app allows for significant customization, letting you tailor the sound to your preferences. The advertised 42-hour battery life held up remarkably well during my testing; I consistently exceeded 24 hours of playtime on a single charge, even with moderate usage of active noise cancellation. The call quality is outstanding thanks to the AI-powered noise reduction. I experienced clear and consistent sound during conversations, even in busy environments.

However, I did find the touch controls to be a bit finicky at times. There were a few instances where I accidentally triggered the wrong command. The water resistance is a welcome feature, but I wish the earbuds had a higher IP rating.

Pros:

  • Exceptional sound quality with deep bass and clear highs
  • Excellent call quality thanks to AI noise reduction
  • Long battery life (exceeding 24 hours)
  • Customizable sound profiles via the Skull-iQ app
  • Comfortable fit with multiple ear gel sizes
  • Multipoint pairing for easy switching between devices

Cons:

  • Touch controls can be inconsistent at times
  • Water resistance could be improved

Overall, the Skullcandy Rail (S2RLW-Q740) earbuds deliver a fantastic audio experience. The combination of superior sound quality, long battery life, and smart features makes them a compelling choice. While the touch controls could use some refinement, these minor issues are easily outweighed by the many positives. I highly recommend the Skullcandy Rail earbuds to anyone looking for a premium pair of true wireless earbuds.
