Pending testing. We publish the score only after the planned field work is complete.
What we know so far
Pending a complete festival-day wear test. We will not call this an all-day pair from a desk test.
Why it is in the test lineup
The long-running budget baseline: one fixed flange size, a cord, and no fashion-first hardware.
Verified product details
20 dB equal-reduction claim; separate lab ratings vary by standard
Standard triple-flange fit
One Standard pair, neck cord, case, and instructions.
A low-profile, stemless triple-flange plug with an acoustic filter path.
What testing still needs to answer
Whether the triple flange earns its equal-reduction reputation with current festival systems.
How the fixed Standard size works across ears without interchangeable tips.
Whether the neck cord helps security enough to offset long-wear contact and handling.
Field logRaveHacks Notes
ER20XS gives this test a useful old-school baseline. It costs roughly half as much as several finalists and puts function ahead of styling, but its Standard triple flange is less adjustable than a multi-tip kit. We will keep the Standard and Universal SKUs separate, report the exact lab-rating language available with the tested package, and let seal consistency—not brand history—drive the protection score.
