Superlux HA4D

I make mainly music with my iPad. Unfortunately it is not able to run a 35Ohm headphones at the volume it should even if the channels are already clipping. In the past I had the Behringer but it had no amplification or at least not noticeable. So I decided to give this little box a try and it does the job perfectly. Noise to signal could be better especially at high gain and you can hear if other things in the same power net starts or stops but hey, for 50€... And I ve already given only 4 stars even if for me it doesnt matter. Maybe if you have very quiet passages it impacts. But I have 2 things to add. First USB power is wonderfull! I hate gear with wallarts that gets lost and then tiolook for remplacement. Net, the power consumtion is very low. I expect that a solar powerbank can run it even if the bank it self is empty. (Not checked yet) Thanks
