QUESTIONS, MEET ANSWERS.

JIMRUC earplugs are reusable earplugs designed to reduce unwanted or excessive sound entering your ears. They are made for situations including sleep, study, work, travel, relaxation, concerts and other noisy environments.

No. They do not play music, connect to Bluetooth or require batteries. They physically reduce the amount of sound reaching your ears, depending on the model and fit.

No. Earplugs reduce sound; they do not normally make your surroundings completely silent. The result depends on the model, fit, ear-tip size and type of sound around you.

Generally, yes, but sounds will be quieter. Speech clarity depends on the model, fit and environment. Choose an everyday-use model when communication matters.

dB means decibels, a measurement used to describe sound levels. Any stated noise-reduction figure refers to performance under specified test conditions.

No. More reduction is not automatically better. Sleep, a concert and an office call for different experiences, so choose for the situation rather than the highest number.

Silence is for sleep and rest. Core is for everyday use, work and study. Flow is for travel and commuting. Pulse is for concerts, nightlife and social events.

Yes. JIMRUC Silence is designed with sleep and quiet environments in mind. It can reduce everyday disturbances, but it does not guarantee complete silence.

You may still hear an alarm, but it can sound quieter. Heavy sleepers or anyone relying on an important alarm should use an additional alert method such as vibration.

Yes. Pulse is designed to reduce surrounding sound intensity while you continue experiencing the event. It is not a guarantee against hearing damage; keep distance from speakers and limit exposure time.

It may reduce some riding noise, but safety comes first. You must remain sufficiently aware of horns, sirens, traffic and other important cues.

Yes. Core is designed for distracting everyday sound while you remain connected to your surroundings. For machinery, construction, firearms, aviation or other extreme hazards, use appropriately certified protection.

JIMRUC includes multiple ear-tip sizes: XS, S, M and L. Choose the size that creates a secure seal without uncomfortable pressure.

Try another ear-tip size. A tip that is too large can create pressure, while one that is too small may not seal. Remove it if discomfort continues and do not force it.

Gently rinse the silicone components with clean water. Let them dry fully before storing them, and avoid harsh chemicals that could damage the material.

Lifespan depends on use, cleaning and storage. Replace them if damaged, permanently deformed, dirty despite cleaning or no longer fitting properly.

We recommend not sharing earplugs that have been inserted into your ears. Each person should use their own for hygiene.

Follow the recommended age and product instructions. For young children, a parent or guardian should decide whether earplugs are appropriate and ensure safe fitting.

If you have ear pain, an active infection, discharge, recent ear surgery or another ear condition, speak with a healthcare professional before using earplugs.

JIMRUC products reduce sound, but no consumer earplug guarantees protection in every situation. For occupational or extremely loud environments, use protection certified for the specific hazard.
