Tips for Best Use

• Always set the volume to its minimum level before wearing, then increase gradually.
• Select an earplug size that creates a snug seal in the ear canal — a proper seal prevents feedback and ensures better sound quality.
• After inserting the amplifier, gently press the earplug with a finger and hold for 1–2 seconds to allow it to expand fully.
• Use a compatible charger only (DC 5V) to avoid device damage.
• Keep the earplugs clean for optimal hygiene and performance.

About Feedback / Howling

Because the microphone and amplifier are in close proximity, some feedback (howling) may occur, especially at higher volume levels. This is a common characteristic of compact amplifiers. To minimize feedback: start at the lowest volume, ensure the earplug fits snugly to seal the ear canal, and increase the volume gradually. Full-digital hearing aids are the only category that can completely eliminate this characteristic.

Frequently Asked Questions

A: The XceeFit SDB-25 BTE sound amplifier provides up to 80 hours of use on a full charge. Charging takes 4–6 hours via a standard USB cable (DC 5V), and a low-power indicator will alert you before the battery runs out.

A: Yes. Each package includes 2 hearing amplifier units, allowing you to use one for each ear simultaneously for balanced, enhanced sound amplification.

Q: Why do I hear a whistling or howling sound from the amplifier?

A: Feedback or howling occurs when sound from the speaker re-enters the microphone. To reduce or eliminate it: always start at the lowest volume, choose an earplug size that creates a complete seal in your ear canal, and gradually increase the volume. A snug-fitting earplug is the most effective way to prevent feedback with a BTE amplifier.
