I went out to try the Nuarl m6 pro today to see if it was worth upgrading my NT01AX over.
First thing I thought listening to them was how absolutely amazing the mids and vocals were! I was just blown away. Not just the best mids I have heard in a true wireless set, but the best mids I have heard every. Absolutely amazing and realistic, super detailed. The imaging and soundstage is even better too, you get that surprise feeling hearing stuff coming fast right or left. The bass is nice and punchy, much quicker, and the highs are very detailed, but everything stays a step behind those amazing mids.
I then tried the liberty pro 2 that were sitting next them. The mids were not nearly as good, but that bass! What the hell is that? They are the heaviest bass I have heard in my life but they don't make the other areas suffer. That is the heaviest bass ever! They still maintain decent mids and good highs, but nothing sticks out like fast bass.
Then lastly I tried the new true wireless set by advanced. The Advanced M5-TWS. They look like custom earphones. They look so beautiful. They also fit like custom buds... Like a glove. Unfortunately after listening to the last two buds, they didn't have the bass if the Soundcore, or the mids or highs of the Nuarl, and just sounded above average in all sectors and rather neutral, nothing sounded as amazing. I guess the fit and the amazing look is what they are about. Unfortunately for the look they kind of dog themselves in the foot and have an led blink at all times under the semi clear shell that uses touch controls, so not easy at all to cover up. I just find the always blinking buds so douchy in the train and inconvenient in the bed room.
Well, I really want this new Nuarls now. Next mission will be convincing the wife to let me upgrade my current NT01AX for 10,000 yen with their trade up program
Conclusion, the m6 pro is a definite step up from the NT01AX. The mids, imaging and soundstage are all a good level up. NT01AX has heavier bass but it's much slower.
