Tips for Better Sound Quality
The HOTTU NB15 delivers Hi-Fi sound with super bass, making it suitable for music, videos, and everyday entertainment.

1. Get a Comfortable Fit
Make sure the earbuds sit comfortably and securely in your ears. A proper fit can improve both comfort and perceived sound quality.

Listening at extremely high volumes for long periods is not ideal. Choose a comfortable volume that allows you to enjoy your music clearly.
3. Stay Within Bluetooth Range
For the most stable connection, keep your phone within the recommended wireless range and avoid unnecessary obstacles between your phone and the neckband.
4. Check Your Audio Source
Sometimes sound quality issues can come from the original audio file, streaming quality, or the device you're connected to.
Try another song, app, or device to identify whether the issue is coming from the neckband or the audio source.
