Very good product

Nice sound quality, perfectly balanced, overall good balanced sound.this amp can be used in small picnic and little music listening. treble is good. loudness is also great. the product doesn't heats up much. because it is purposefully used a low capacitor so that heat can be managed.Coming to the quality of the hardware used it average quality. you will get 3773 instead of 3055 due to its availability , also 3773 is 5-10% better than 3055. You might state that the bass output is low that is due to the low value of capacitor used 35v 2200uf, if you know a little bit of electronics change it with 50v 4700uf, or you can also parallel with a 4700uf along with the 2200uf, then the bass output will increase a lot and overall sound output will also increase. but keen in mind by doing so the heat of the transistor will also increase be prepared for that.if you somehow encounter breaking sound from the Bluetooth even if it is minute it is due to low power, just add a 25v 470uf capacitor to the power input of the Bluetooth and it will be gone.i have not measured the output of the transformer when i do, i will update it. it is made of aluminum due to the lower cost overall.cabinet is small which is very nice, very much potable. but is little wiggle boggle but is ok.the thing i did not like at all is the power cable is of too low quality and fuse is not given. you can add it easily though.overall i can state people those who don't want dj all the time this is a perfect amplifier with little flaw as stated above. can be easily used for mic program. it is made in India by our small retailers we must support them.

It keeps on switching between modes automatically. In MIC mode, the output sound is too low. There will be buzzing sound from speaker always. In bluetooth mode, the song breaks between so many times. It is a horrible product which i cannot able to return. Do not waste your money in this useless box.

The media could not be loaded. I haved hooked up to the 4-TR 3055 to my 30 year old technics speakers...Performs very good.Had some heating issues on amplifier, and burning smells. Contacted seller, and he is very responsive. Said it is expected. And after couple of days the smell is not there. But it still heats up big time from the backside.Also lacking is the owners manual. You are supposed to figure out the functions on your ownOverall rating....Music quality 8Value for money 9Product quality TBD (To be decided)Will update review after using for another 3 monthsEdit: Still performing as amazing as ever... Heating issues are irrelevant now, because I now learned of impedance and analog sound amplification..To sum up: One of the best buys I have ever made👍Edit: You know for sure this is a good buy, when throws it so badly around the house (photos attached)Have ordered for another one

Good make shift arrangement for your sound needs. Though it has a host of utility features

Low quality product. Please take back this

Every thing is good but remote control is small.. It should be big like tv remote

The design and arrangement is good.But the sound quality does not meet our expectation.Connected to pioneer speakers but, not base sound, only treble is ahead, many settings tried. But failed. Can use only as an amplifier in a open stage
