Reusable corded polyurethane foam earplugs — SNR 33 dB, bullet-shaped

Bullet-shaped plugs made of slow-recovery PU foam (up to 1 minute) — a time-tested form factor for industrial hearing protection. SNR 33 dB ensures reliable reduction of noise from pneumatic tools, pressing equipment, and metalworking machines. The cord connects the pair and prevents the loss of plugs — a safety requirement at most engineering and food production sites. When washed with warm water after a shift, the pair retains its performance for several uses — savings compared to fully disposable analogs for constant personal use.

The cord connects the pair of plugs and allows you to hang the earplugs around your neck during conversation or in a quiet zone. The plugs are always at hand — no need to take them out of your pocket or packaging every time.

The classic cylindrical shape is intuitively understandable when putting on. Polyurethane foam softly takes the shape of the ear canal and evenly distributes pressure along the walls.

A noise reduction level of 33 dB effectively lowers industrial noise, construction equipment noise, and pneumatic tool noise to a safe level. Suitable as earplugs for work in noisy rooms during long shifts.

With careful use and regular washing, a pair can be used for several shifts. This is beneficial for personal constant use unlike fully disposable cordless analogs.

Designed for noisy production with periodic transitions between zones of different noise levels. The cord is a key convenience: take them off when talking to a technician, hang them around your neck, return to the noisy zone — put them back on. SNR 33 dB covers woodworking, metalworking, construction, and food production tasks (where the cord is mandatory by safety regulations). Suitable as noise earplugs for sleep in moderate urban noise — PU foam is soft for long-term wear.

If earplugs are needed only for sleep, the cord causes discomfort in a side-sleeping position: consider the cordless bullet-shaped or silicone tree shape. For noise levels above 95 dBA, upgrade to TECRON Classic form corded 37 dB. For long-term reusable use, silicone plugs (corded trees or cordless) have a fundamentally longer lifespan than polyurethane.

The only bullet-shaped polyurethane corded plugs in the catalog. They occupy a niche between budget cordless bullets (33 dB) and TECRON Classic form corded (37 dB, certified brand). In terms of SNR (33 dB), they are comparable to 3M 1110, but without the brand markup. They surpass the corded silicone tree in noise reduction level (33 vs 29 dB) in acoustically heavy conditions.
