I'm super happy with it overall and for the price. I use it to power some Campfire Audio Andromeda S's and although there is some slight hissing when silent, when anything is playing it work great. I've used it for music on my Chromebook, Windows, and my Note 9 (with USB c adapter), works with everything great. I have yet to try it with my Sennheiser HD 800 S's as I don't tout those around town, but I imagine it would do alright. Also used it for gaming on my laptop and helps improve some of the low end for gunshots and explosions imo. It's a simple, easy to use portable DAC/Amp and helps give a bit better of sound than Samsungs hardware.
