Quality Guarantee & Product Care Policy

Effective Date: June 4, 2026

Premium Quality Commitment

At Eternal Rest, we guarantee every product meets trillion-dollar luxury standards. Each Bluetooth Sleep Mask undergoes rigorous quality control: 100% light-blocking verification, acoustic performance testing (105dB signal-to-noise ratio), Bluetooth 5.2 connectivity validation (20m range), battery integrity check (300mAh capacity), fabric durability assessment (cooling breathable material), and speaker positioning accuracy (0.2-inch ultra-thin profile). Products failing any checkpoint are rejected. You receive only perfection.

Product Care Instructions

Cleaning Protocol

• Remove Bluetooth speakers before washing (speakers are detachable via velcro slots).
• Hand wash mask fabric in cold water (max 30°C/86°F) with mild detergent.
• Do NOT machine wash, bleach, tumble dry, or iron.
• Air dry flat in shade, avoid direct sunlight (prevents fabric degradation).
• Do NOT submerge speakers in water (IPX0 rating - no water resistance).
• Wipe speakers with dry microfiber cloth only.
• Cleaning frequency: Every 7-10 days for optimal hygiene.

Storage Guidelines

• Store in provided pouch or cool, dry place away from humidity.
• Avoid extreme temperatures (below -10°C or above 45°C damages battery).
• Keep away from sharp objects, magnets, and corrosive substances.
• Do NOT fold or crease speaker housing (causes internal wire damage).
• Battery maintenance: Charge to 50% if storing over 30 days.
• Velcro care: Close velcro tabs when not in use (prevents lint accumulation).

Usage Best Practices

• Adjust velcro tape to fit head girth 20-25 inches (do NOT overtighten).
• Position speakers directly over ears for optimal sound (adjustable slots).
• Charge fully before first use (2-hour charging time).
• Use provided USB cable only (prevents over-voltage damage).
• Do NOT use while charging (safety precaution).
• Keep away from children under 3 years (small parts choking hazard).
• Discontinue use if skin irritation occurs (hypoallergenic but individual sensitivities vary).

What Voids Warranty & Guarantee

The following activities or conditions will immediately void your ETERNAL REST warranty and quality guarantee:

• Water damage (submersion, excessive sweat, rain exposure).
• Physical damage (drops, crushing, tearing, pet damage).
• Unauthorized modifications (opening speaker housing, rewiring).
• Third-party chargers (causes battery swelling/fire risk).
• Commercial use (rental, hotel placement, resale without authorization).
• Negligence (leaving in hot car, washing machine, dryer).
• Normal wear and tear (fabric pilling after 12+ months, velcro weakening).
• Cosmetic issues not affecting function (minor stitching variations, color fading).

Quality Metrics & Lifespan Expectations

Component Lifespan

• Battery: 500+ charge cycles (approximately 18 months daily use).
• Bluetooth Chip: 5+ years (no degradation expected).
• Speakers: 3-5 years (gradual volume decrease possible).
• Fabric: 2-3 years with proper care (cooling properties may diminish).
• Velcro: 1-2 years (adhesion weakens with lint/dust accumulation).
• USB Port: 10,000+ insertions (standard durability).

Performance Standards

• Light Blocking: 100% (tested in complete darkness environment).
• Noise Reduction: Passive 15-20dB (fabric density + ear coverage).
• White Noise Output: 85-95dB at maximum volume (safe hearing range).
• Bluetooth Range: 20m line-of-sight, 10m through walls.
• Battery Life: 15 hours white noise mode, 35 hours music mode (at 60% volume).
• Charging Efficiency: 0-100% in 2 hours (with 5V/1A adapter).

Quality Assurance Process

Pre-Shipment Inspection

• 1. Visual examination (fabric defects, stitching quality, color consistency).
• 2. Functional testing (power on/off, Bluetooth pairing, volume controls).

• 4. Battery validation (charging capability, voltage stability).
• 5. Light-blocking test (photometer measurement in controlled environment).
• 6. Comfort assessment (pressure distribution, ear cup positioning).
• 7. Packaging integrity (box condition, accessory completeness).
