The Real Differences Between Peltor, Sordin, and Earmor
A helmet without proper hearing protection isn’t a kit, it’s a liability. Modern active headsets process external audio in under 5 milliseconds, clipping impulse peaks above 82 dB while letting whispers and footsteps through. That’s the gap between a $30 set of foam-and-electronics and the three brands operators actually argue about.
Three names show up in every serious loadout discussion: 3M Peltor, MSA Sordin, and Earmor. They solve the same problem in radically different ways. After running each one through training cycles, range days, and a few miserable rainy patrols, here’s what stood out.
3M Peltor ComTac XPI: The Reference Nobody Disputes
The ComTac XPI sits at the top of the Peltor range and shows up on more military procurement lists than any other active headset on the market. NRR is 23 dB, SNR 28 dB on the European listing. The digital electronics react in roughly 1 to 2 ms to impulse noise, which is why a single rifle shot beside you doesn’t leave a ringing tail.
Sound separation is where it earns its reputation. Voices come through with a tight, almost over-clean signature. You can pick up a radio call layered under suppressed fire, which sounds trivial until you’re in a CQB shoothouse and missing a callout costs the run.
Build quality is what you’d expect at €499: aluminum hinges, sealed PCB, gel cups standard. NATO 6-pin downlead options for whatever PTT and radio you’re running. It pairs cleanly with Team Wendy or Ops-Core ARC rails through Peltor’s own adapters.
What it isn’t: comfortable past hour 6. The headband padding is thinner than Sordin’s, and the gel cups exert real clamp pressure. Operators who run 10-hour shifts often pad the band with moleskin or shift weight to a helmet rail mount to take pressure off the skull. Battery life sits around 200 hours on 2x AAA, which is fine but well below Sordin.
For a serious communication headset that needs to integrate into MBITR, PRC-152, or any encrypted system without drama, this is still the default.
Sordin Supreme Pro-X: The Long-Day Choice
Sordin is what people pick when they actually wear the headset all day.
The audio profile is the opposite of Peltor’s: warmer, less compressed, closer to how your ears would hear without the cups on. Some operators describe the Peltor as “tactical radio voice” and the Sordin as “human voice.” Both descriptions are accurate.
Specs on paper look weaker (NRR 18 dB, SNR 25 dB) but the gel cushions seal better against most face shapes, and the measured attenuation in real conditions tends to match Peltor closely. The waterproof battery compartment is genuinely sealed; I’ve had mine submerged for 30 seconds with no issue. 600+ hours on 2x AAA, roughly three times what Peltor delivers.
Two real weaknesses worth knowing. The boom microphone picks up more wind noise than Peltor’s, and the side-mounted controls sit in awkward positions if you’re wearing thick winter gloves. Neither is a dealbreaker for most users.
At €349, it’s the headset I recommend to instructors, range officers, and anyone whose ears stay open from 0700 to dusk.
Earmor M32H: What €110 Actually Buys You
Earmor changed the conversation when the M32H landed. Not because it beats Peltor or Sordin (it doesn’t), but because it’s genuinely usable at a quarter of the price.
NRR sits at 22 dB. Reaction time is slower than the two Swedish heavyweights, closer to 5 to 7 ms, which you can hear if you’re paying attention but won’t notice on a normal range day. The boom mic is decent. The awareness mode works. The modular ARC rail mount means you can rip it off the helmet and run a headband adapter in about 90 seconds.
The reasons it costs €110:
- Plastic hinges instead of metal. They survive, but feel cheap.
- Foam cups standard, gel cups sold separately
- Electronics produce a faint hiss in quiet environments
- Build tolerances are inconsistent unit-to-unit; QC is the trade-off
What you get in return: PTT compatibility with Baofeng, Motorola, ICOM, Kenwood, and Peltor connectors out of the box. That’s a feature the Swedes charge €60+ adapters for.
For airsoft players, private security teams kitting out 8 operators on a budget, or anyone building a first serious loadout, the M32H makes more sense than buying one Peltor and waiting two years to afford the second.
Specs Side by Side
| Feature | Peltor ComTac XPI | Sordin Supreme Pro-X | Earmor M32H |
|---|---|---|---|
| NRR / SNR | 23 / 28 dB | 18 / 25 dB | 22 dB |
| Reaction time | ~1-2 ms | ~2 ms | ~5-7 ms |
| Battery life | ~200 h | ~600 h | ~350 h |
| Weight | ~340 g | ~310 g | ~280 g |
| Price (2025) | €499 | €349 | €110 |
Which One Should You Actually Buy?
Cut the marketing language and it comes down to three questions.
Are you running encrypted comms in a unit that demands proven gear with a documented service record? Buy the Peltor. The reaction time advantage is real, the integration ecosystem is unmatched, and procurement officers don’t second-guess it.
Do you spend more than 6 hours a day with the headset on, and care more about not getting a headache than about saving 1 ms on impulse response? Buy the Sordin. It’s the one I personally wear most.
Are you building your first kit, running airsoft, or kitting out a team on a budget? The Earmor M32H gets you most of what the others do for a quarter of the price. Just don’t expect it to last ten years of hard use.
One Last Thing
Hearing protection is the one piece of kit you can’t unbreak. Tinnitus is permanent. A blown eardrum doesn’t grow back. Whichever brand you land on, wear it on every range trip, every breach drill, every loud environment, even the ones that “don’t seem that bad.”
The headset that’s actually on your head beats the perfect headset still in the box.
