Fosi Audio SK-01 Headphone Amplifier Review

[gufkl]

Mine has developed a power-related intermittency -- it apparently didn't like to be left powered-on and charging, so I'm going to leave it off and charging until I actually want to use it -- which fortunately isn't all that often in my use case -- and see if that skirts the problem, which manifests as a flickering power LED and no output. Other than that, the thing is more than adequate IMO and FWIW. At least that flickering LED warns me when it's not going to work.

I'm wondering if its battery is at fault and if it would work or could be modified to work with the battery removed...

i have the same problem

i have the same problem

Follow-up: In my case, the problem turned out to be the M-to-F USB extension cable I was using -- all is OK now!

I use the device between a mobile record player (high level line out) and a Sennheiser HD650 on the road. Works fine and suits my rather large hands.

i tried different cable and adapter, sadly still the same.

Sorry about that.

If they can make one with a variable loudness like Yamaha including the Bass, Mid, Treble controls.. this will be enough to adjust the sound to taste. PEQ is qill be a better bet but I can't ask for too much..
