After a week of listening I can say that the FA1 sound way better of my former Sennheiser Momentum IEM. The sound is crystal clear, the mids and highs are incredible and the bass is very good. I just needed time to get used to the new sound sig.

I received my FA1 yesterday. The first listening tests left me a bit disappointed because they sound very cold, thin and dry respect to Sennheiser Momentum IEM I was using before. Mids and highs are good but the bass response is very weak. Maybe the FH1 would suit my taste better?

Sorry folks, I find hard to understand the OTG thing. Could I use my Android phone as a source (via USB connection)? Would the DX120 be powerful enough to drive the Sennheiser HD660S through balanced output, using a 4.4->2.5 connector?

Hi folks, I used to listen through my notebook->dac->head amp->Sennheiser HD650 but I had to sell everything (except for the notebook). I understand that I could use the Q5S with my notebook as a source; could I use my Android phone as a source (via USB connection)? Would the Q5S be powerful...

Ok, I opened it, nothing appears to be broken inside, but still it's not working. I will have another look tomorrow.

Well, of course i saw the little hole, but could not find the screw... I'm gonna check better!

Hello, my sweet Corda Ha1 Mk2 fell to the floor and stopped working. I am trying to open it to check if there's anything broken inside but I have no idea how to remove the volume knob. Pictures of the amp are here, cordaha1 As you can see, to open the amp I need to remove the knob... but how...
