How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want purely passive sound isolation with a wired, no-battery earbud that blocks up to 37 dB of outside noise, choose Shure SE112; if you need active hearing enhancement, Bluetooth audio and switchable protection modes for the track or the range, choose AXIL GS Extreme NASCAR.
• Shure SE112 — biggest strength: Passive sound-isolating design that blocks up to 37 dB of ambient noise, with a fixed 3.5 mm cable and no battery to manage.
• Shure SE112 — biggest trade-off: No Bluetooth, no hearing enhancement, and the cable is not detachable — it cannot be swapped if it wears out.
• AXIL GS Extreme NASCAR — biggest strength: A 3-in-1 design that blends Bluetooth audio, hearing enhancement (up to 6x) and noise isolation, with 25 hours of run time per charge.
• AXIL GS Extreme NASCAR — biggest trade-off: It is a battery-dependent wireless product, so it needs charging and a 2-hour charge cycle before use, and its protection is electronic rather than purely passive.
• Who the Shure SE112 is for: Listeners who want dependable, corded isolation for commuting, travel, gym sessions or stage use without ever thinking about charging.
• Who the AXIL GS Extreme NASCAR is for: Shooters, hunters, mechanics and motorsport fans who need to hear their surroundings while keeping loud impulse noise in check — and want music and calls in the same earbud.
The Shure SE112 is built around one idea: keep the noise out so you can hear what you actually want to hear. Its sound-isolating sleeves create a seal in the ear canal, and Shure rates that seal as blocking up to 37 dB of ambient noise. That is passive isolation in its purest form — no chips, no modes, no charging. You push them in, the seal takes hold, and the outside world drops away.
The rest of the package matches that philosophy. A single dynamic driver handles full-range sound, the housing is plastic with a rounded profile, and the fixed 3.5 mm cable runs 50 inches and can be worn over the ear or hanging straight down, depending on what feels better during long sessions. There's a shock-resistant ring guarding the driver against sudden impacts, and Shure backs the build with a two-year limited warranty. Frequency range is listed at 20 Hz to 20,000 Hz, impedance around 16–17 ohms, so it's easy to drive from a phone or laptop. The fit kit includes multiple sleeve sizes plus a carrying pouch — and that fit detail genuinely matters, because a loose tip means you lose both bass and isolation.
So who should buy it? Anyone who wants a corded, low-maintenance earphone for noisy commutes, flights, gym work or monitoring on stage, and who values a durable design over wireless convenience. Who should skip it? If you want Bluetooth, hands-free calls, or the ability to amplify quiet sounds around you, this isn't that product. There's no jack-free option here, and the cable is not detachable — a deliberate durability choice, but it does mean the cable is the end of the road for the whole unit if it ever fails.
The AXIL GS Extreme NASCAR is a different animal entirely. It's marketed as a 3-in-1 earbud: Bluetooth earphone, noise-isolating headphone, and electronic ear protection in one shell. The core trick is that it doesn't just mute the world — it enhances quiet sounds up to six times normal hearing while compressing anything at or above 85 decibels. That's the combination that matters at a shooting range, on a construction site, in a workshop, or at a race track, where you need to hear a voice or a warning while a loud impulse gets clamped down.
The feature set is genuinely rich for the category. Bluetooth 5.0 handles audio and hands-free communication, and independent volume controls let you blend hearing enhancement and protection simultaneously, or switch cleanly between protection mode and audio mode. Ear hooks keep the buds anchored during movement, and the rechargeable lithium battery lives on the lanyard, delivering 25 hours of run time or up to 120 hours of standby, with a 2-hour charge time over USB-C. The box includes small, medium and large max-protection foam tips plus a small silicone set, a lanyard adjustment, a T-shirt clip and a quick start manual. Impedance is 30 ohms, sensitivity 29 dB, driver type dynamic, frequency range 20 Hz to 20,000 Hz. Warranty is one year.
Who should buy it? Shooters, hunters, mechanics, track-day regulars and anyone in a loud, intermittent-noise environment who also wants music and calls from the same device. Who should skip it? Anyone who wants a purely passive, battery-free solution, or who dislikes managing a charge. There's no 3.5 mm jack here — it's wireless only — and the electronic protection depends on the battery being alive.
Side-by-Side: Which Should You Choose?
• Best for maximum passive noise blocking → Shure SE112. Up to 37 dB of isolation from the ear seal alone, with zero electronics in the chain.
• Best for battery life → AXIL GS Extreme NASCAR. 25 hours of run time and 120 hours of standby, recharged in about 2 hours via USB-C. The Shure has no battery at all, which is its own kind of advantage.
• Best for wireless convenience → AXIL GS Extreme NASCAR. Bluetooth 5.0, hands-free calling and independent volume controls for audio and protection.
• Best for a wired, zero-maintenance setup → Shure SE112. Fixed 50-inch 3.5 mm cable, no pairing, no charging, no firmware, nothing to remember before you leave the house.
• Best for long-wear comfort during activity → Shure SE112. Over-ear or hanging-down cable routing plus a multi-size fit kit, and a seal that stays put during exercise and travel.
• Best for staying anchored during fast movement → AXIL GS Extreme NASCAR. The ear-hook shape and lanyard-mounted battery keep the buds in place when you're moving.
• Best for durability confidence → Shure SE112. Shock-resistant driver ring, reinforced fixed cable and a two-year limited warranty versus AXIL's one year.
In my opinion, the deciding question isn't which one is "better" — it's whether you want isolation you never have to charge or protection you can tune. If your noise problem is steady and you just want it gone, I'd buy the Shure SE112: the up-to-37 dB passive seal, the corded simplicity and the two-year warranty make it the more predictable, lower-fuss choice for commuting, travel and listening. If your noise problem is loud, sudden and something you still need to hear around — range days, hunting, workshops, the track — I'd buy the AXIL GS Extreme NASCAR, because no passive earbud can give you enhancement, Bluetooth and switchable protection modes. Different jobs, different tools.
how to noise cancelling earbuds
There's a key distinction here. The Shure SE112 doesn't use active noise cancellation at all — it uses sound-isolating sleeves that physically seal the ear canal and block up to 37 dB of ambient noise. The AXIL GS Extreme NASCAR also relies on sound isolation, but pairs it with electronic compression that clamps sounds at 85 dB or louder. Neither is a traditional ANC headphone; both work through fit and electronic processing rather than anti-noise microphones.
how to noise cancelling earbuds work
Passive isolation works mechanically: a correctly sized tip creates an airtight seal, and that seal is what blocks outside noise, which is why Shure supplies a fit kit with multiple sleeve sizes and warns that a poor fit ruins both sound quality and isolation. The AXIL's electronic side works differently — it enhances quiet sounds up to six times normal hearing while compressing anything at or above 85 decibels, so loud impulses get pulled down instead of simply being blocked.

If you're pairing with an iPhone, the AXIL GS Extreme NASCAR is the relevant one here, since it uses Bluetooth 5.0 for audio and hands-free communication. The Shure SE112 is a wired 3.5 mm earphone, so it needs a compatible jack or an adapter rather than a wireless pairing. Neither product's data sheet lists any Apple-specific features or app integration, so treat them as standard wired and Bluetooth devices respectively.
how to use noise cancelling earbuds
With the Shure SE112, the whole routine is getting the seal right: swap sleeves until one fits snugly, then insert and let the isolation do the work — you can wear the cable over the ear or hanging down. With the AXIL GS Extreme NASCAR, you charge it for about two hours, then use the independent volume controls to blend hearing enhancement and protection or switch to Bluetooth audio mode. Foam tips give the most protection; silicone is the quicker, everyday option.
