I have both the M560 and the M1060 which I just got today and am listening to as I write this.
At $200 for the M560 and $300 M1060 these certainly qualify as one of the first true audio bargains of 2017!
I'm listening to the M1060's using a newly built Intel Nuc computer into an Audioquest Dragonfly Red with plenty of volume at 42 on the Windows mixer and 100% using Foobar 2000 straight off my network NAS with about 7k FLAC ripped CDs and hirez downloads.
My first album up is the tremendous Duncan Sheik Covers 80's which are his very idiosyncratic mostly acoustic versions of popular songs from the eighties. Sheik is a masterful producer and imbues these songs with lots of atmospherics. The M1060's, while literally only minutes out of the box, are dripping in detail but are not harsh or fatiguing. I just switched to Brian Bromberg's Jaco tribute album that I ripped from the original DVD-A 96k/24b files to test the bass response. Wow, all the woodiness for his acoustic bass are completely revealed in his cover of "Portrait of Tracy". I wouldn't be surprised as the M1060's get warmed up the bass will improve even further? Switching to the latest Dizrythmia "Too" (an english prog super group that put out albums once every 20 years or so!) I am listening to the song "How did I let you get so old" which features the legendary english bass player Danny Thompson. Again the acoustic bass just sounds wonderful here. Gavin Harrison's drums propel the song along with all the finesse he is known for. The M1060's don't leave me wishing for more, it's just right. I could go on and on?
Regarding the M560, I am also very impressed. At $200 for a Planar magnetic, it is going to put heat on the competition - if there really is any at this price.
Both the M560 and M1060 have excellent build quality and come with nice presentation boxes and cases. One small oddity is that the M1060 only comes with a 3.5" connector and no 1/4" adapter in the box. Seems like an odd ommision by Monoprice since they sell their own adapters for pennies on the dollar? Also, the M560 doesn't differentiate between left or right with their cable since by using 3.5" stereo connectors at the headphone the correct channel is always selected. You just look for the L or R on the headphone itself. In contrast, the M1060 uses IEM style click connectors that have black on black and almost impossible to see L and R markings on them? The headphones themselves have no L or R markings!
Anyone interested in the burgeoning headphone market will be compelled to audition these new entrants out as soon as possible. The big downside is the buzz is so strong on them that they are going in out of stock at an alarming rate.
