If you want a feature-rich pair for calls, choose Skullcandy Rail; if you need longer stated battery life and adaptive noise cancellation, choose TOZO NC20. For everyday switching between a phone and laptop, I lean toward Rail’s multipoint pairing and voice-focused microphone features. For listening where background noise is the bigger concern, NC20’s hybrid ANC and 55-hour total battery figure are the stronger on-paper fit.
Skullcandy Rail vs TOZO NC20 at a Glance
• TOZO NC20’s biggest strength: adaptive hybrid active noise cancellation and a stated 55 hours with the case; its trade-off is that the provided specifications do not describe multipoint pairing, voice controls, or a call-focused microphone feature.
• Rail is for: people who move between two devices and want app personalization, Tile finding, and a clear set of call-related features.
• NC20 is for: people who prioritize noise cancellation, wireless case charging, and longer stated battery life over the specific switching and call features listed for Rail.
Skullcandy Rail makes sense for someone whose earbuds need to handle more than music. Its multipoint pairing connects to two devices at once, with transitions intended to make it easier to answer a phone call while audio is playing from a laptop. That is a practical detail for a workday split between video, music, and incoming calls. The product description also identifies a Clear Voice Smart Mic designed to isolate your voice and reduce background noise. That makes Rail the more clearly call-oriented choice on paper, though the available information does not establish how it performs in every noisy setting.
There is room to tailor the listening experience, too. The Skullcandy app offers Personal Sound by Mimi, EQ adjustment, and Stay-Aware Mode. Hands-free voice control covers media and other app features, while touch controls are available on the earbuds. Tile finding technology is another useful extra if misplaced earbuds are a recurring annoyance, though finding them depends on registering the product in the Tile app. The listed IP55 rating adds sweat and water resistance, a relevant feature for workouts and damp commutes.
Rail’s battery is listed as up to 42 hours in total: 9 hours in the earbuds and another 33 hours in the case. A 10-minute Rapid Charge is stated to provide 2 hours of listening. Those figures support regular use with less frequent case charging, but they are below NC20’s stated totals. Skip Rail if your first priority is the longest stated battery life or adaptive ANC; those are the areas where NC20 has the clearer advantage in the supplied specifications.
TOZO NC20 is the more natural fit if you want earbuds built around blocking outside sound. Its adaptive hybrid ANC is described as adjusting to the surroundings in real time. The listed claim of blocking up to 99% of noise is a manufacturer specification, not a guarantee that every voice or sound will disappear in every environment. Still, ANC is the feature that most clearly separates NC20 from Rail in this comparison. If you listen during a commute or want fewer distractions around you, that feature deserves serious consideration.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-19 · 7 min read · Independent comparison
NC20 lists up to 15 hours from a single charge and up to 55 hours total with the case. The case supports both USB-A-to-USB-C charging and wireless charging. The description also points to an ergonomic shape and multiple ear-cap sizes, with comfort positioned for commuting, exercise, and even wearing while sleeping. These are intended-use claims rather than a guarantee of fit for every ear. Skip NC20 if you specifically need the two-device multipoint switching, Tile finding, or call-focused microphone details listed for Rail; those features are not specified for NC20 here.
• Best fit for calls between phone and laptop → Skullcandy Rail. Its multipoint pairing is explicitly designed to connect two devices, and its product description calls out a voice-focused microphone.
• Best for adaptive active noise cancellation → TOZO NC20. Its hybrid ANC is described as adjusting to nearby noise; Rail lists sound isolation and Stay-Aware Mode, not ANC.
• Best stated total battery life → TOZO NC20. Its listed total is up to 55 hours, compared with up to 42 hours for Rail.
• Best for a quick top-up → Skullcandy Rail. The stated Rapid Charge figure is 2 hours of listening after 10 minutes of charging.
• Best for wireless case charging → TOZO NC20. The NC20 case supports wireless charging as well as USB-A-to-USB-C charging.
• Best for app-based sound personalization → A close call. Both list app EQ customization; Rail also specifies Personal Sound by Mimi and Stay-Aware Mode.
• Best for finding misplaced earbuds → Skullcandy Rail. Built-in Tile finding is listed, with registration in the Tile app required.
• Best for sweat and water resistance → Skullcandy Rail. Its IP55 rating is specified; the NC20 information supplied here does not list an equivalent rating.
For calls, do not treat a long battery figure or ANC claim as a substitute for call-specific information. Rail has the more relevant details on paper: a microphone described as reducing background noise, plus multipoint pairing for handling two connected devices. NC20’s specifications emphasize noise cancellation for listening, but the supplied information does not give a comparable microphone description. If calls are your main reason for buying, that difference matters more than a broad sound-quality claim.
Think about where you will wear the earbuds. NC20’s ANC could be useful when you want less surrounding noise, while Rail’s Stay-Aware Mode is intended to let you remain more aware of your surroundings. These features serve different preferences; neither is automatically right for every commute or workplace. Rail also has a stated IP55 rating for sweat and water resistance, a concrete point to weigh if workouts are part of the routine. No corresponding rating is provided for NC20 in the information used here.
Finally, match the extra features to your habits. Rail has a specific answer for switching between a computer and phone, customizing controls, and locating misplaced buds. NC20 has the longer stated battery total and wireless case charging. If you are searching for sleep headphones for calls, neither product sheet establishes that either pair is designed for comfortable overnight calling. Likewise, someone looking for a gaming headset for calls should not assume either pair has gaming-specific features: the supplied details do not describe a gaming mode or latency performance. Check the current price on Amazon using the page’s button if price is part of your decision, but choose based on the features you will actually use.
My Verdict
Rail has the stronger call-related specification: its description identifies a microphone designed to isolate the voice and reduce background noise, and it supports multipoint pairing with two devices. The supplied NC20 details do not describe a comparable microphone feature.
The listed total is up to 55 hours for NC20 and up to 42 hours for Rail. NC20 also lists up to 15 hours from a single charge, while Rail lists 9 hours in the earbuds and a 10-minute rapid charge that provides 2 hours of listening.
NC20 lists adaptive hybrid ANC and describes real-time adjustment to surrounding noise. Rail lists sound isolation and Stay-Aware Mode, but the supplied specifications do not identify active noise cancellation for Rail.
Rail explicitly lists multipoint pairing for two devices. The information provided for NC20 does not specify multipoint connectivity, so I would not count on that feature based on these specifications.
