KILLS THE SNORE
A mic and speaker in each bud cancel low-frequency noise on top of passive foam — up to ~90% reduction of a snoring partner.
ENGINE DRONE
The same cancellation subtracts traffic, ventilation and plane drone — the steady band below ~3 kHz that foam and silicone only muffle.
SIDE SLEEPERS
The 4 adds softer Comply-style foam tips and a more oval shell that follows the ear canal — its main upgrade over the 3.1.
ALL-NIGHT BATTERY
~28 hours on a charge from the USB-C case — a red-eye and the hotel night after it.
NO SETUP
No Bluetooth, no app, no pairing — lift them out of the case and ANC fades in over ~20 seconds.

  The catch — co-equal billing, always

$299 buys you one trick. No music, no app, no white noise, no alarm — and it only subtracts steady low frequencies. Voices, alarms and sudden clanks still come through. If passive plugs have not actually failed you, a $25 Loop Quiet 2 is 90% of the benefit for 8% of the price.

Traps — this verdict avoids

Trap 01

"Cancelling" is a misnomer

Almost nothing in this category cancels anything. Foam, silicone and filtered plugs only attenuate — they turn noise down, they do not remove it. One product here, the QuietOn 4, actively cancels, and only below ~3 kHz; even it leaves voices, alarms and sudden clanks audible.

Trap 02

Lab seal, real ears

Published NRR/SNR figures are measured under an ideal seal. Real-world attenuation runs 5-15 dB lower and depends entirely on insertion depth and ear-tip fit — the headline number is not what your ear gets.

Trap 03

Nightly wear has a cost

Sleeping in plugs every night is linked to earwax impaction and canal irritation. Clean reusables on the maker's schedule and bin foam pairs often; QuietOn's built-in wax guard helps but does not eliminate it.
