Works perfectly, the connection is super simple, the sound is very good, the low and sharp settings are effective, the Bluetooth range is a bit fair but not more than for its competitors, the manufacturing and materials used are of good quality. And to finish the price at the top. You can go there without worry!

Did not work unless my phone was near the pre-amplifier. (10cm)

The antenna did not make contact. (central pin too short / pushed in too deep)

I had to repair it.

Once this was done, it works really fine.

It arrived quickly, perfectly packaged and sealed. It is a new item.

Despite being an economical device, it is a preamplifier that improves the audio tone significantly (in my case of active speakers connected to the PC where the basses dominate and the sound is somewhat dark). With the preamplifier connected, the sound acquires a little more clarity in the contrast of graves-guts.

The volume can also slightly increase (it is not an amplifier).

Good device, I give you a rating on 5 -quality-price relationship- of 4.2.

Definitely adds bass and treble but the bass distorts above 3/4. Gives a warmer sound but i feel when on for a while the sound becomes muffled and i have to turn it off for a while or add more treble. This does not have a ground connection, why?

The truth is that I do not notice any quality improvement in class AB amplifiers, if it is true that I notice a different sound but not better. I have even replaced the tubes with others, they sound different but it still doesn't sound better than my amplifier without this tube preamplifier.
