Absolutely Satisfactory. Not only does it power the headphones at 300 Ohms and above that I purchased it for, the Treble and Bass knobs are exceptional. They don't just raise or lower entire spectrums flat, but in the Treble knob serves to increase clarity without making things sharp while the Bass knob increases Bass without making it destroy the mix! Even when used in a car, all things above apply, turning mediocre car stereos into something truly special. Don't even think about purchasing this product, just do it! You will absolutely be pleasantly surprised!
I bought the k5 pro because i wanted to upgrade from the q4 but i thought it would be louder and in terms of sound quality the k5 pro is not much different, you have to turn the bass and treble knob almost all the way to get good sound.I tried them with my dt 900 pro x and my audio technica m50.
This amp was okay for a few months. Then it sporadically would cut off power to my headsets microphone requiring a restart of the amp. This issue began to happen more and more often to where now it wont power any microphone for more than a few minutes before requiring a restart. Im not sure where the issue lies, but it's frustrating
I use sennheiser hd58x jubilee headphones and was originally plugging it directly into my computer's audio ports, but it was not delivering enough power. I needed a decent amp/dac solution so I searched and stumbled on multiple suggestions for this.It was very simple to set up it's literally plug and play. I used the usb-c cable provided and plugged it directly into the amp to my computer then just plugged my headphones into the amp. There's three knobs you can play with to adjust the overall volume, trebble, and bass. This device is perfect.
This is great. Drives my Sennheiser HD599s well, and setup was simple. Plugged into my PC's USB-C port and worked right away.I like that I can connect it to my work laptop and my personal and switch between the two easily and it's super flexible for my workflow.Plus, it looks great on my desk, and despite nested among other electronics on my desk it never gets hot.
