The M0 pro has a flap covering, the M1s does not. The standard cases do not cover either.

I'm surprised to hear that he R3 sounds warmer than the M1S. My only experience with Hiby is the R3 Pro Saber and that is far from warm.

What are these IEMs?

Seen. Which now begs the question why Shanling placed a 20k track limit on the better spec'd M1S? If the reportedly clunky Hiby R3 ii can handle 50k tracks why not the new Shanling device?

You know that the Hiby r3 ii has a 50k limit based on experience or speculation? The hardware is what caused the 20k limit and last I checked the Hiby R3 ii has the old x1000 - same as the Shanling Q1, M0 Pro and Hiby R3 Pro Saber.

I wasn't aware that the Hiby R3 II had been released yet but from your criteria it looks like a win for Shanling. Not sure why Hiby would release a new device using the old x1000. Very odd decision.

They show up on albums that are properly tagged - artist and album info that displays just fine on the M3U and Q1.

M1s got another firmware update before the m0 pro gets one?

Am I the only person who prefers touch controls? I keep hearing about people complain about the Momentum 4's controls but they're easily my favorite from any wireless headphones that I own or have tried.

I haven’t had this experience. I’ve used this device successfully for several hours via Bluetooth headphones.

Interesting review and comparison.

Neutron app has been good for me, it doesn't look as pretty as Poweramp (which has the best UI) but it is very versatile and allows you to get optimum use of your device.

It's very much possible.

M1S. Shanling devices tend to have a far more enjoyable sound than their Hiby counterparts.
