Independent shopping perspective
The Korena take
27dB four-flange reusable earplugs for loud stages. The pick for drummers and anyone standing in front of a full band rig.
Strong match
Who this is for
- Drummers and anyone playing beside a loud backline
- Rock and metal gigs, rehearsal rooms with a full band
- Standing near PA stacks or in the pit at a show
Consider the trade-offs
When to look elsewhere
- Quiet acoustic sets where you need full detail
- Cueing off subtle vocal or room detail on stage
- Anyone who needs to hold conversations while wearing them
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
4-flange design
An extra sealing ridge over triple-flange plugs. Deeper seat and a tighter seal, which is where the higher reduction comes from.
Detail 03
One size
The flanges compress to a range of canals, so no sizing decision. Trim-free fit for most adults.
Detail 04
Thermoplastic elastomer
Washable and shape-retaining. Survives being stuffed in a gig bag pocket night after night.
Detail 05
Hypoallergenic material
Safer for long sets and for players whose ears react to cheaper plugs.
Detail 06
Reusable
At this price a single pair covers a whole tour's worth of nights if you don't lose them.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Are these too much for band practice?
For a full loud band, no. For a quiet acoustic rehearsal 27dB will bury the detail, and you may want a lighter plug instead.
02Can I hear myself sing with these in?
You'll hear yourself mostly through bone conduction, which sounds different from usual. Most singers adjust, but it takes a couple of sets.
03Do they fall out while I'm playing?
The four flanges seat deeper than typical plugs. Push in until they feel seated and they should hold through an active set.
04How do these differ from the high-fidelity pair?
More reduction, 27dB against 12dB, and a fourth flange. This pair prioritizes protection; the other prioritizes hearing detail clearly.
