Skullcandy’s pitch with the Rail ANC is focused on the features - particularly active noise cancellation. That said, there’s still enough attention paid to the basics, ensuring that you get a fairly rounded experience on the whole. There’s no fancy codec support here, which means that sound quality will be pretty uniform regardless of which source device you use; it’s a good thing if you intend to use the headset with multiple devices such as smartphones, laptops, or tablets.
Active noise cancellation is adjustable on the Skullcandy Rail ANC, but even at the highest level the effect isn’t significant. It does offer some level of noticeable noise reduction, but it wasn’t quite enough to even mute basic household noise such as a spinning ceiling fan, or the low hum from an open window. It did help in making playback a bit more focused and easier to pay attention to.

Sound quality itself wasn’t bad, with the Skullcandy Rail ANC delivering a warm sound that will work well with most genres. The headset manages to find a bit more bass in everything, giving a firm rumble to even typically subdued and smooth tracks such as Something Got Me Started by Simply Red. For more aggressive tracks such as Bad Boy by Yung Bae, the punch fits right in and gives the sound a bit of character.
Fortunately, the low-end rumble doesn’t make things sound odd or unpleasant in any way; the mid-range gets some decent impact on the Skullcandy Rail ANC too.The highs seem to taper off a bit faster than usual, but this makes for an interesting sonic signature that is admittedly right up Skullcandy’s alley.
Long story short, this isn’t incredibly detailed, revealing, accurate, or anything of the sort, but it’s clean enough and aggressive in a fun way. That said, you do need to turn the volume up to get the most out of the earphones; the Skullcandy Rail ANC isn’t for soft listening, and you need to be as audacious as the design to get the most out of it.
Battery life on the the Skullcandy Rail ANC is very good, delivering around 6.5-7 hours per charge on the earpieces even with ANC switched on. The charging case will give you about three extra charges for a total of close to 28 hours per charge cycle.
