I bought the red colour Shanling M0 Pro, it is a great sounding device. Holds good amount of music in high res quality, initially had issues playing a few FLAC files which were resolved after firmware upgrade. The latest version is 1.6 so I recommend you update your device to the latest. UI is simple but would have loved some thumbnail views to select albums instead of all text view.
Overall great sound and supports all the latest features of a dedicated Music player. Physical buttons to change track would have been better than one button to power on off and setting actions.
Battery life could have been better if it had been more than 24 hours. Currently lasts about 1.5 days if you are a frequent listener.

It was decent build as expected like previous MO.,bit stylish for the age.Single dial system ,minimalistic is functional and ergonomic.Clicks switches song gud.Unlock requires a swipe.Dial is gud.Sound signature pretty decent for iem and may work for less power required Headphones too.Cleaner signature and may require you to dial up more than 50% for decent volume.Charge looks like around 6-7 hours decent.Screen bit small but over time we will get used to and works great.Portablity is the usp of this DAP for travel or bedside listen.May be a Spotify or Apple lossless in future will be great add on.Otherwise Gud DAP for iems and a portable DAC too for compact carrying people.Case is decent too from.Shanling.Satisfied overall.but dont think its very powerful though.

I recently made a purchase of this product slightly over a week ago from the audio store, and I am pleased to express my satisfaction with the package and delivery, which were executed in a neat and expedited manner. My primary intent for acquiring this item was to cater to my portable audio requirements during various activities such as walking, driving, and commuting.

Upon testing, I found the sound stage to be suitably expansive, allowing for a satisfying auditory experience. Furthermore, the device exhibited the capability to power my in-ear monitors (IEMs) effectively. The audio quality itself can be described as neutral with a subtle warmth, which enhances the overall listening experience.

Transferring my music collection was a seamless process, as the user interface proved to be both smooth and devoid of any apparent glitches or inconveniences. In terms of battery performance, the device showcased commendable backup capabilities, ensuring a prolonged and uninterrupted usage.

Taking into account its features and performance, I am inclined to recommend this compact yet powerful audio device, as it offers excellent value within its price range. However, it is worth noting that the absence of a balanced adapter is the only drawback I encountered during my experience with the product.

Seriously you have to consider this player for your offline music. The best tiny player with a dual chipset has a lot of power to deliver any IEM. My self using IE 900 & IE 200 along with 64 Audio Fourte. All my IEMS are very well sounding with M0 Pro. 

At this price point, dint expects this player sounds that great and even powerful but really thrilled once plugged in. I won't listen with a 3.5 jack plug. Personally purchased a 3.5 to 4.4 mm Balanced adapter which is from Shanling and recommended for M0 Pro. 

Let your offline tracks be of any quality the M0 will make them sound the best. I had my offline tracks for many years now. Some of the tracks are downloaded from various sites not been much quality but this player sounds the best. As per my observation, this player delivers a great listing experience with decent separation, mids, and lows. At the price point, it's a wonderful gem in a 15k Segment player. 

Pros: 
1. 100% Best DAP at this price point
2. Lots of power and musicality. 
3. with a 4.4 mm balanced adaptor you will see the real side of M0 Pro.
4. Decent power battery 
5. The quality of the player looks very good (won't look cheap ) 
6. The software also won't have much lag. ( Fine to operate )

Cons: 
1. Not included the 4.4 Balanced adaptor 
2. Separate purchase of a case 

Final Words: Recommend to everyone, If you are new to the audiophile journey and need some DAP for your offline tracks then this is the best to choose without any question. If you already have some flagship DAP and want to have something for traveling and when you move to some un-network areas where you felt like listing your favorite tracks then this should be in your pocket. 

Thanks for the Pritam always stands for best recommendations and suggestions for audiophiles. Love you all time. Thanks again:)
