I just unpacked my new M8 I was pleased by the great unboxing the experience was very pleasant. Everything felt very high quality. The device is also very well built. Nice touch with the leather case!
The screen protector was not pre-applied and I found it not being so easy to install, I had many bubbles left. Hope they dry out in few days.
The volume know is super responsive I was very happy to see that finally it been accomplished.
Spotify seems to work fine, I haven't really yet had time to test it properly, I started the download process and burn in so we wait
I have encountered a different problem, my wave files dont load my album arts

only flacs seems to work. I dont have this problem with Hiby R8 and 1z

And also google service keep screaming in notification that the google service is not official and need to contact the manufacturer, I fixed this by muting the notification.
I found in battery menu you cannot disable battery optimisation feature but you can manually disable for each app. So I disabled it for shanling player and spotify.

As it goes for sound performance is yet to early to make any feedback so I can only share first impression.
I found M8 to sound fuller and warmer then R8 and for those who like more musical and bassier feel the M8 provides here.
Technically yet cant say but slightly feels the more advanced dac in m8 seems to perform a little more in an advantage here. I also feel the device need more burn in as the bass dont feel yet fully open and deep.
R8 on other hand is more thin and brighter a little, not as fun and bassy. R8 bass feels more rumbly and deep but that device has 500 hours of playing time so I expect m8 to improve significantly in 200hours.
Sound wise r8 and m8 are 2 different signatures and will fullfil different audiophile lovers. M8 for folks that are after warm and musical tuning and R8 more neutral natural with a slight musical twist. I feel R8 has a more technical approach while M8 more fun and musical.
M8 is dead silent ! Absolutely 0 hiss ! I am super impressed I did my most profound hiss test and its absolutely silent like a black hole! Just wow.
I also love the volume knob of m8 its so so tactile and pricise. Even when screen is off its still super responsive and precision adjustable with ease.
R8 in comparison has also a volume knob but its so unreliable and not responsive on first turn which is quiet frustrating. I could adjust volume while screen was on but with screen of its simply not intuitive and unreliable as you never know where did you end up with the volume level. With M8 no such problems!
Of course R8 is much faster in ui navigation and loading the album arts and menus. R8 is simply rocket fast, m8 is noticably behind. It doesnt make m8 bad at all as I prefere m8 sound over r8...
M8 also feels better built hardware wise, its elegant all black and sturdy stiffer buttons. The swappable idea with different connection types is ingenious! Works super flawlessly and feels like it will last for long time.
Will share more impressions later so stay tuned.

I still think wm1z has an edge in sound performance but m8 is really there close close to it behind. If I am lucky I will meet with a friend and recompare the 1z vs m8

By memory I feel 1z sounds better. But but m8 can do streaming and has an absolutely dead silent noise floor !
