How to Use

1. Clean the ear canal before use.
2. Charge the device fully, then turn the dial to N.
3. Start with the volume at its lowest setting and gradually increase.
4. Try the included earplugs (S/M/L) and select the size that fits snugly with no air gaps.
5. Insert the amplifier into the ear canal and gently press to fully seat the eartip.
6. If you notice feedback or whistling, re-seat the device or try a larger earplug size.

Tips to Minimize Feedback / Whistling

• Always start at the lowest volume and gradually increase.
• Ensure the eartip fully seals the ear canal — an airtight fit reduces feedback.
• Clean your ear canal before inserting the device.
• After inserting, press and hold the device gently for 1–2 seconds to allow the eartip to fully expand.
• Try a slightly larger earplug size if whistling persists.

Important Usage Notes

• Use the included USB charging cable with a 1–2A charging head (charging head not included — a standard USB wall adapter is recommended).
• Do not use an incompatible charger, as this may damage the device.
• Turn off the amplifier when not in use to preserve battery life.
• Keep the eartips clean and dry after each use.

Frequently Asked Questions

Q: Does the XceeFit SDB-01 sound amplifier require disposable batteries?

A: No. The XceeFit SDB-01 features a built-in rechargeable battery that is charged via the included USB cable. A full charge takes 4–6 hours (8 hours recommended for the very first charge) and provides up to 40 hours of use, so you won't need to purchase replacement batteries.

Q: Why does the device produce a whistling or howling sound, and how can I stop it?

A: Whistling (feedback) occurs when amplified sound re-enters the microphone — a common characteristic of compact in-ear amplifiers. To minimize it: start at the lowest volume and increase gradually; use a larger earplug size to create a better seal; and press the device gently into the ear canal for 1–2 seconds after insertion to ensure the eartip is fully expanded. A snug, airtight fit is the most effective way to prevent feedback.

Q: What eartip sizes are included, and how do I choose the right one?

A: The package includes three earplug sizes (Small, Medium, and Large). Start with the medium size and test for comfort and seal. If you experience feedback or the device feels loose, try the next size up. The correct size should feel snug and create a complete seal in the ear canal without discomfort.

Q: Can I use any USB charger with this device?

A: The device is compatible with a standard USB charging head rated at 1–2A (not included in the package). Using an incompatible or excessively high-current charger may damage the device, so it's important to use an appropriate adapter.
