Strings sound noticeably lush and also bass guitars & bass-synth sounds great. Tubiness is hard to describe, to me it has a wider soundstage, slower roll-off and somewhat a certain amount of reverb. The sound is rich and full and the harmonics tic... Read More

Attached photo shows the little bear connected to my idsd and mounted together using dual lock.

Great sounding product, overall product build is good, but quality and readability is something to be desired. It is not perfect but what do you expect for $70. Hopefully this helps out some prospective buyers. Talk about excellent customer service.

Double sided tape on the battery is an annoyance but not a big deal since its snug anyway. Only complaint is the charger plug is simply *, i have to have it pushed up in a certain direction to make any contact for the charger to work.

It adds a considerable amount of headroom to the volume of my system. Amazon has the best hassle free return policy on the internet. If you have nothing else, it's perfectly fine as a desktop unit.

Cons

The build quality is neat, but the 1/8 headphone output is horrible. My galaxy s8 drives my hd650s just as well as this, and distortion becomes very evident when the volume is turned up more than halfway on the amp.

Quality

The sound quality is very rich and warm with a full bodied sound field

Completely satisfied with the product and their customer service

The better the quality of the audio you feed it will correspondingly produce clearer and mre dynamic output from the little bear b4

Like most quality amps they amplify and stay neutral

Price

Other wise it is a great product for the price

Packaging/appearance

After a couple hours of use it doesnt get very hot and sounds great right out of the box

Competitiveness

I was using a yaqin cd3 vacuum tube buffer between my preamp and amplifier

Stop reading this and buy a schiit magni heresey for 99 with lots of clean accurate power

At least for megood headphone amplifieronly cons is accessories very bad chinese charger and already breaking 3

This unit definitely sounds like a 5star amp but only when music is coming out both channels
