The sound quality is superb. I haven't used it often but sounds like the day I got it. I got this Fiio M11 from somebody on here, he didn't have it long and just wasn't using it. It came without a charger, nothin but the box and a plastic cover, I will be giving a charger with this along with its plastic cover, I can't find the box but will send in a robust Xiaomi phone box in addition to some other protective packaging.

This is the link to a rather amusing Z Review on the M11: https://youtu.be/mg_z34lJ0qY

This Link tells you about its specs: https://www.headfonia.com/fiio-m11-review/5/

It has one problem, somewhere along the way I must have dropped it [I honestly do not recall doing so] and it now has 2 small chips on the glass at the edge of the bottom of the screen. The chips caused 2 closed loop hair line cracks on the face of the glass screen as shown in the pictures. They have zero to do with how this thing plays. Regrettably It is an eye sore but one I became accustomed to. The fact that I took a lot of pics of them emphasizes them maybe a little unfairly but of course once seen they can't be unseen. The thing is they aren't THAT bad, but they are bad if aesthetics are as important for you as the sound.. The cracks have no bearing on the screen touch ability. I can't feel them at all with my fingers.

I am selling because I'm looking to upgrade. I looked at the prices of the Fiio M11 sold secondhand on ebay and the lowest was being sold for $600. I think $485 is a fair price considering the cracks. The machine runs well, no problems at all. I did contact Fiio in China to see if they do screen repairs and they will if I send it but again, if you can get passed the cracks, then all is good.

The M11 comes with double SD card slots and 32 Gig on board.
