I have the same problem...

Great! Thanks for the info

wow... sending a parcel into china that cost only 10-15 USD? What courier did you use?

Anyway, what was the total cost for repair by FiiO with shipping? Thanks

Yes exactly, they have my x7 since monday, they wrote to me today that the problem didn't show up, so I asked them to let the player warm up for at least an hour and so they can test it, it is strange that they give the customer from Slovakia immediately answer and the local customer from the...

Thank You for your response, i have send x7 to czech local service, they are checking it right now, i will let them know about the battery issue, thanks

I tried also to unlug the amp and was feeding the line out from top of the body of x7 to my darkvoice tube amp, still the same...

Dear FiiO, two and a half year ago I bought FiiO X7 mk II, unfortunately now on headphone out from am3a module and also from the line out the sound started to have permanent beep noise and music become very very distorted, the problem occurs in pure mode and in android mode, fiio player and...

FiiO told me that the smaller bore is 1.50mm, I cant find any damper with this diameter... so maybe we can try the 1.37mm?

Hi, yes, it can be ordered from mouser.com https://www2.mouser.com/Electromechanical/Audio-Devices/Speakers-Transducers/_/N-awp4u?P=1yyy7vr

Looking forward to your measurements of changing the filters... Thanks

OK, FiiO replied to me just now, the bore with white dumper is for highs and the small bore is for the mids (red arrow in the picture), the diameter is 1,5mm, the other bigger one without damper is for bass...

In this new version of FiiO APP internet radios in DLNA are finaly working!!! But! No VIPER's effects? No Way for me, rolling back :-( It is a pity...

I found that i can order knowles dampers in 4 diameters: 1,12mm, 1,37mm, 1,78mm and 2,08mm, does anybode know which one is for mids? Thank You

So which one bore is for what purpose? There are 3 bores, 2 bigger and one small, i think the knowles dampers fits only in the bigger bores, or I'm wrong? Maybe FiiO could help to explain? Thanks

I just ordered some knowles dampers from digikey, so im very excited to see the results... after i removed the mesh from FH5 i see that fiio is using only one damper, is it for mids?

Hi to all, i am new in tube amplifiers, i am using my 336se with 6AS7G (Svetlana 6H13C) and CV181-Z Treasure, im planning to change the Svetlana 6H13C for Telefunken 6080 tube? Is this a upgrade or just sidegrade? What would be the differences in sound? Thanks
