Coleson FD190 Bluetooth Earbuds

These are in-ear wireless Bluetooth earbuds, mainly designed for gaming scenarios with noise reduction, and support APP adjustment functions. The highlight is that they can work with a mobile app to adjust sound effects, and also feature pop-up positioning for easy locating of the earbuds. Suitable for daily commuting or gaming entertainment. Note that the noise reduction is software-optimized rather than physical deep noise cancellation, and the price is low, so performance should be taken as actual usage.
