C420 Invisible In-Ear Sound Amplifier — 40-Hour Battery, Charging Case & Full Accessory Kit | Très Elite
$238.28
Description
Forty hours. That's how long the C420 runs on a single charge — and when it does need power, the included case tops it up four more times before you ever need to find a cable. Tiny enough to disappear inside the ear canal, the C420 is built for people who want to hear more clearly without announcing that they're doing so. It comes with everything: six ear tips across multiple sizes, cerumen guards, a cleaning brush, a tuning stick, and a full manual. Just pick your colourway and get on with your day.

Setup & Use
Charge the device fully via the charging case before first use. Connect the case to a USB power source using the included Type-C cable. Insert the device into your ear canal using the ear tip size that fits most comfortably — a snug seal improves sound quality. Use the tuning stick to adjust settings as described in the user manual. Replace cerumen protectors periodically to maintain sound clarity.
Note: If you experience discomfort, feedback (whistling), or any adverse reaction during use, discontinue immediately and consult a healthcare professional.
Care & Maintenance
Use the included cleaning brush to remove earwax and debris from the device tip after each use. Replace cerumen protectors when sound quality diminishes. Wipe the exterior with a dry, soft cloth. Do not expose to water, moisture, or extreme temperatures. Store in the charging case when not in use. Keep out of reach of children. Do not attempt to disassemble or repair the device yourself.
Frequently Asked Questions
Q: Is this a medical hearing aid or a sound amplifier?
A: This is a Personal Sound Amplification Product (PSAP) — it amplifies sound for individuals who have difficulty hearing in certain situations. It is not a prescription medical hearing aid and has not been clinically evaluated or approved as a medical device. If you have significant or worsening hearing loss, please consult an audiologist before purchasing.
Q: Does the 40-hour battery life refer to continuous use?
A: Yes — according to manufacturer specifications, the device provides up to 40 hours of continuous use per charge. Actual battery life may vary depending on volume level and usage conditions. This claim has not been independently verified by us.
Q: What does the charging case do exactly?
A: The charging case stores the device and recharges it when not in use. It holds enough power to fully recharge the device up to four times before the case itself needs to be plugged in — making it ideal for travel or extended time away from a power outlet.
Q: What are cerumen protectors and why do they matter?
A: Cerumen protectors are small filters that sit at the tip of the device to prevent earwax from entering and blocking the sound port. Replacing them periodically (when sound quality starts to diminish) keeps the device performing well and extends its lifespan.
Q: Are there any import restrictions I should be aware of?
A: As a health and assistive device, this product may be subject to additional import scrutiny or health product regulations in some countries. Buyers are responsible for verifying that this product complies with local health device import and use regulations before ordering.
