Description
Create a quieter space for sleep, travel, study, and everyday focus. Lundrea S1 combines a compact in-ear profile, soft dual-layer silicone tips, and a mechanical dial that lets you choose among three passive noise-reduction settings—without Bluetooth, batteries, charging, or an app.
Three adjustable levels
- Low: lighter everyday noise reduction
- Medium: study, office, and travel
- Higher: bedtime and noisier surroundings
Turn the built-in mechanical dial to select the setting that suits your environment.
Designed for comfortable rest
- Soft, dual-layer silicone ear tips
- Low-profile ergonomic shape
- Multiple ear-tip sizes for a more personalized seal
- Compact fit suitable for many side sleepers
Ear shape and comfort vary. Select the tip size that seals gently without painful pressure, and discontinue use if irritation or discomfort occurs.
Washable and reusable
Remove the silicone tips before cleaning. Wash the tips with mild soap and water, rinse thoroughly, and allow them to dry completely before reattaching. Wipe the ABS components with a soft, dry or slightly damp cloth. Do not immerse the mechanical components.

Shipping
This Shipping Policy applies to orders placed through . Lundrea currently ships to eligible addresses within the United States. Available delivery methods and charges are shown at checkout.
Order processing and shipment estimates
Orders are reviewed before fulfillment. Any processing, shipment, or delivery estimate shown on a product page, at checkout, in an order confirmation, or in a shipping confirmation is an estimate based on information available at that time. Business days exclude weekends and U.S. federal holidays.
We maintain a reasonable basis for any shipment time we state. If no shipment period is stated, we intend to ship a properly completed order within 30 days, as required by applicable U.S. law. A properly completed order includes successful payment authorization and the information reasonably necessary to process and ship the order.
Unexpected delays
Inventory changes, carrier disruptions, severe weather, address issues, peak demand, security review, or other circumstances may delay fulfillment. If we learn that we cannot ship within the time promised—or within the legally applicable period when no time was promised—we will provide a delay notice and, where required, offer the option to consent to the revised shipment date or cancel for a full and prompt refund. We may cancel and refund an order that we cannot fulfill.
Shipping charges and taxes
Shipping charges, available service levels, discounts, and applicable taxes are calculated and displayed before you submit payment. We do not add undisclosed mandatory shipping charges after checkout.
Tracking
When tracking is available, it will be sent to the email address or other contact method provided with the order. Tracking information may take time to update after a label is created. A label-created status does not necessarily mean the carrier has taken possession of the package.
Delivery estimates
Delivery time begins after the carrier accepts the shipment. Carrier delivery dates are estimates and are not guaranteed unless the selected service expressly states otherwise. Lundrea is not responsible for delays caused solely by the carrier, weather, service interruptions, or events outside our reasonable control, but we will assist with reasonable delivery inquiries.
Address accuracy
Please review your name, delivery address, apartment or unit number, and contact information before placing an order. Contact us immediately if an address needs correction. We cannot guarantee changes after fulfillment begins. Additional shipping costs caused by an incomplete, incorrect, refused, or undeliverable address may be charged to the customer to the extent permitted by law.
Split shipments
Items in one order may ship separately. If that happens, you may receive more than one shipping confirmation or tracking number. You will not be charged an additional shipping fee solely because we divide an order into multiple packages.
Missing, lost, or damaged packages
If tracking shows an unusual delay, the package is marked delivered but cannot be located, or the package arrives damaged, contact us at as soon as reasonably possible. Please first check the delivery location, household members, neighbors, building management, and any carrier delivery notice. We may ask for photographs, confirmation of the shipping address, or cooperation with a carrier investigation. Available remedies depend on the facts, carrier findings, and applicable law.
Refused and unclaimed deliveries
Packages that are refused, unclaimed, or returned because of an incorrect address may be treated as a return after they arrive and are inspected. Original and return shipping costs may be deducted from any refund when permitted by law, unless the issue resulted from our error.

This includes sleep masks, aromatherapy or botanical inserts, pillow covers, lumbar or neck pillows, and similar products that have been worn, placed against the face or body, washed, or removed from sealed hygiene packaging. These restrictions do not limit your rights if an item arrives damaged, defective, materially different from its description, or if applicable law provides otherwise.
Damaged, defective, or incorrect items
Please inspect your order after delivery. If an item is damaged, defective, missing components, or different from what you ordered, contact us as soon as reasonably possible—preferably within 7 days of delivery—so we can evaluate the issue. We may request clear photos or video of the product, packaging, shipping label, and damage. When the issue is confirmed, Lundrea will provide an appropriate remedy, which may include replacement parts, a replacement product, a refund, or another remedy required by law. We will cover reasonable return shipping costs for confirmed damaged, defective, or incorrect items when a return is required.
Change-of-mind returns
For an approved return that is not caused by our error or a product defect, the customer is responsible for return shipping and any loss or damage occurring during return transit. We recommend using a trackable shipping service and retaining the receipt. Original shipping charges are not refundable unless required by law or the return results from our error.

Order changes and cancellations
Contact us as soon as possible if you need to change or cancel an order. We will try to help, but we cannot guarantee changes or cancellation after processing or fulfillment has started. If the order has already shipped, the applicable return rules will apply.

Questions, answered.
Product-specific guidance for features, fit, setup, care, and everyday use.
Are these earplugs comfortable for sleeping?
Lundrea S1 uses a lightweight, low-profile shape and soft dual-layer silicone tips to help reduce pressure during extended wear. The compact design is intended to stay comfortable through the night, including for many side sleepers.
Will they hurt my ears like traditional earplugs?
Multiple silicone tip sizes let you choose a gentler, more secure fit. The earplugs should seal without painful pressure; stop using them and try another tip size if you feel soreness or irritation.
How effective is the noise reduction?
The manufacturer states an adjustable passive noise-reduction range of 18–32 dB. Actual performance varies with the selected level, ear-tip seal, fit, and sound frequency.
Will they fall out while sleeping?
The in-ear shape and multiple tip sizes are designed to support a stable fit. Choosing the correct tip size is important for both comfort and helping the earplugs remain in place.
Are they suitable for side sleepers?
Their compact, low-profile design sits closer to the ear than many bulky earplugs, making them suitable for many side sleepers. Comfort still depends on ear shape, pillow firmness, and sleeping position.
How are they different from regular foam earplugs?
Unlike disposable foam earplugs, Lundrea S1 offers three mechanical noise-reduction settings, reusable silicone tips, multiple fit options, and a compact design intended for extended wear.
Are they certified hearing protection?
They are intended for sleep, travel, study, and everyday comfort—not as a substitute for certified occupational or high-noise hearing protection. Do not use them when hearing warnings, alarms, traffic, or instructions is necessary for safety.
