likely doesn't support MQA;
problems with older i products
volume automatically set to max when connected etc..

read no complaints about hiss sound nor sound quality..

me interested to know actual user comment as well.

W1/W2 應該更好

I think you should bring your phone and IEM to try them out in MK.

It is now very consumer friendly for shops to offer on site trials and you don't need to depend on the words of mouth.

No one can tell you exactly which one is the best as hearing is believing and your budget can significantly affect your choices.

But do share your comment thereafter.
I am happy with my M12 after firmware update while still miss the chance to try PEE15 last time.

Finally, for base noise,  just wonder if the extra money can make a great difference when you're on the street / in MTR...unless there is obvious abnormal hiss/hum noise like what I heard from the BEAM 2 that I eventually returned.
