Good. Sounds great except the high white noise.
Got this to use it with my old pc speaker. Looks compact and packed with many features on a tiny PCB. Functions and sounds great when you use it with 10watts 8 ohms and there will be no heating of the amplifier chip. Using a 4ohm speaker causes the ic amplifier ic to heat up. The only drawbacks I found was that it sometimes struggle to read the files in the flash drive and when turning on, it says ‘bluetooth mode’ at high volume which is annoying and volume can’t be condrolled. The worst thing is that it gives a high audible white noise when played at full volume which was solved by adding a smd capacitor to the bluetooth ic audio output pin and to the ground.Overall I would suggest you to not buy this if the white noice at high volume is the concern. Value for money product but potentially high price at the kind of cheap hardware used and wish if there would be a stereo one of this.Tips: Use 8 ohms or higher to avoid audio cracking and distorsion at full volume and I would not recommend using a 3.7v lithium cell and using the charging feature as it has no protecton and is only limited by a diode in series. Use directly with 5v instead.

Good one.
Item is working good with 18650 battery and charging. Intial announcement is too loud. Volume button, power button, mini usb port direct power working without batteries and also FM Radio works. All in all, good mono BT amplifier.
