LISU Ersai-A1 Soft Foam Noise Reduction Sleep Ear Plugs
Create a quieter environment for rest, travel or focused work with the LISU Ersai-A1 soft foam ear plugs. The seller presents these compact acoustic earplugs with an ergonomic curved design intended to provide a secure, comfortable fit while reducing distracting environmental sound.
The technical specification lists the primary function as Noise Reduction Sleep Aid and confirms that the product is non-electronic with no batteries required. The visible retail packaging additionally displays SNR 35dB and 10 PCS; these are retained as seller-packaging information rather than independently verified acoustic test results.

Comfortable Passive Noise Reduction for Everyday Use

Compact ear plugs can be easy to carry for airplanes, hotels, trains and other travel situations.
Passive noise reduction may help reduce awareness of selected background sounds during quiet work or study.

There are no Bluetooth connections, charging routines or electronic active-noise-cancellation components.
The seller imagery shows a compact organized case for storing multiple plugs together.
Passive Ear Plugs vs. Active Noise Cancelling Headphones
The seller title uses the phrase “Noise Cancelling Ear Plugs.” Because the supplied technical table clearly states Electronic: No, these are passive ear plugs rather than electronic active-noise-cancelling headphones.
- Passive ear plugs reduce sound by physically limiting how much external noise reaches the ear canal.
- They do not use microphones, processors or electronic noise-cancellation signals.
- They do not require Bluetooth pairing or battery charging.
- Performance varies with fit, ear anatomy, insertion and the type of environmental sound.
Ear Plug Care & Storage
- Handle the ear plugs with clean, dry hands.
- Follow the manufacturer’s cleaning or replacement directions on the delivered packaging.
- Do not continue using a plug that is torn, permanently deformed, heavily soiled or damaged.
- Keep plugs dry between uses unless the manufacturer specifically states that they can be washed.
- Store them inside a clean case away from dust and contamination.
- Avoid sharing ear plugs between users.
- Replace them when they no longer maintain a secure, comfortable fit.

Warnings & Safety Notes
- Insert Gently: Never force an ear plug deeply into the ear canal. Stop if insertion causes pain or significant pressure.
- Remove Slowly: Ease the plug outward gradually rather than pulling it abruptly.
- Keep Clean: Dirty plugs or contaminated hands may transfer debris into the ear area.
- Do Not Use Damaged Plugs: Replace plugs that become torn, hardened, heavily soiled or permanently deformed.
- Reduced Awareness: Ear plugs may make alarms, traffic, voices and warning sounds more difficult to hear.
- Do Not Use Where Hearing Is Required for Safety: Avoid use during driving, cycling in traffic or other activities where hearing warning sounds is important.
- Ear Health: Seek appropriate medical advice before inserting ear plugs if you have active ear pain, drainage, recent ear surgery or a known ear-canal condition.
- Not a Medical Sleep Treatment: “Noise Reduction Sleep Aid” describes the product’s intended sound-reduction use. It does not mean the product treats insomnia, sleep apnea or another sleep disorder.
- Not a Snoring Treatment: Although the seller specification contains the field “Anti Snore Nose Clip,” the pictured product is marketed as ear plugs. Ear plugs do not treat the underlying cause of snoring.
- Industrial Hearing Protection: Do not rely solely on the seller-displayed SNR 35dB statement for workplace, shooting or hazardous-noise protection without verifying that the exact delivered product meets the required standards for that use.
- Keep Away From Young Children: Small ear plugs can present a choking hazard.
