Good product In AMAZON GOOD SELLERS NIC PRODUCT GOOD WORKING 5V DC WORKING TOW SPKER NIC BASS . WITH BLUETOOTH Sherda audio in bluetooth speaker boxSurround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener (surround channels). Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three "screen channels" of sound, from loudspeakers located in front of the audience at the left, center, and right. Surround sound adds one or more channels from loudspeakers behind the listener, able to create the sensation of sound coming from any horizontal direction 360° around the listener. Surround sound formats vary in reproduction and recording methods along with the number and positioning of additional channelsBluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables.

This product took 10 days to get delivered. Nothing to my surprise, the bluetooth module works fine only with the amplifier. It can't be connected directly to an earphone. As it's pre- amplifier signal is very weak. There exists a irritating ground loop noise which makes it useless. Unless you add a 16v 4700 uf capacitor to reduce it. The modules are easy to install and the sound quality is average.

Very good quality chips. I'm familiar with pam8403, as I used it earlier but bought from different vendor. I wanted to try these as well and surprisingly these also worked very well. Especially bluetooth module which connects very quickly. Very well printed board. You will not require any installation manual to assemble these. This combo is worthy. Only one lack I found in pan8403 is it sounds bad (not clear) at high volume. I'm facing this issue with my earlier board as well. Not sure how to fix this.

Good quality Modules. Viz,.. TP4056 Li-Ion charging module, Bluetooth TX module and 3W+3W stereo Amp module. Tested and all works fine. The only problem was with the packaging. The modules were very badly packed. Being SMD devices, the seller should have taken care to pack them properly. Luckily the PCB nor none of the SMD components broke Off. Any way I am happy that all 3 worked.

Audio amplifier board is to much small as aspect avg. Sound quality, volume is good for room, Bluetooth module is very little so soldering carefully ,and charging module with led indicator charging in red when it's full charge led glow blue👌Base lover not satisfied with board

It has amazing sound quality whether it's bass or trebbles it's really awesom, the range is quite decent for a 3.0 version. The charging module does its job although it gets a little warm at 750mA but it's negligible so and the listing price is also pretty acceptable so, just go for it without any doubt!
