This is one of the most capable USB DAC I have used, if you do not want to rear a lot about how this behaves in detail, let me tell you, this is more balanced, has better end to end extension, is more neutral and colourless than the L&P W2. It doesn’t lack anywhere and doesn’t have any coloration of its own. It just simply doesn’t add anything to the IEM/headphone’s character, letting it show its own quality and character.

I did an AB between Beam 3 plus and Fiio KA3 to check if a mic or inline remote will work in USB mode (no, they don’t work with anything) and the first thing that caught my attention is the much cleaner and refined output of the Beam 3 plus. I have had reviewed a handful of USB dongles and I can easily state that this is easily the most meticulously tuned dongle. It just simply doesn’t have any flavoring. Not extra treble sparkle or fuller lower end, doesn’t try to emphasize or deflate the mids either. I will credit the AMP chip here but that’s not mentioned, in any case USB audio wise, this is a straight Ace. No jitter or splashiness, no added smoothness or extra grains is found here.

Thanks to the extra bit of power it does help IEMs expand their stage without introducing any hollow space. Layering and separation is top notch too. Since all the IEMs behaved differently it’s hard to point at one thing and say yes, this is the particular improvement we can find with this dongle. 


This has to be one of the most capable BT adapters with very good power and higher detail but as usual Bluetooth audio is not as capable as the wired one. It does have the support for high resolution audio in LDAC and APTX-HD but just like every other BT device the treble region does not maintain the transparency and liveliness of the USB mode and it does struggle a bit with high speed tracks. There is little to no difference when it comes to lower and mid range performance. MIC performance too is very good, it’s slightly on the sharper side but is good with vocal frequencies. I do wish it had a clip of some sort to put it on the shirt but it is what it is.
