After spending 3 days (more than 30 hours) with the Nuarl N6 pro, I am still impressed by how this tws sound.
-Build quality: Everything is made of plastic, but a high grade one at that. It feels solid and the buds themselves are pretty light compare to 1more ANC. The case is made of plastic too and I've seen people complain about the hinge being flimsy and its not, it just feels flimsy, but it is pretty solid actually. The magnet to close the lid is the strongest I've seen on any tws case.
-Sound quality: The bass is tight and punchy with enough body. It is not a basshead tws for sure. The mid is forward and not thin nor thick, for me it just right. The treble is airy, cymbals has nice decay and attack. Details is very good, timbre is probably the best on any tws that I have so far, instrument separation is spot on. This Nuarl N6 pro has taken the first spot on my tws list. Also, the N6 has the highest volume available on any of my tws so far. I normally listen with my S20+ at 80-90% volume on my 1more ANC, 70-80% on my mifo07, 60-70% on N6.
-Battery life: 8 hours on AptX is plenty and you can even increase it even further by selecting AAC to 11 hours.
-Control: Volume +/-, play/pause, <</>>, voice assistant are all there on the earbuds. And you can use only one of them (Left or Right only) while still having all the controls.
-Connectivity: The bluetooth range and signal is very stable. It connect to my phone (Samsung S20+ and my surface book in literally under 3 seconds). I haven't test the length of the signal yet because I am still quarantining myself in my bedroom.
-Improvements: With this style of tws, you would expect to have ANC or ambiance mode. The N6 definitely has the space for any of those features. The case is kinda on the bulky side, but not as bad as Mpow M5 and it can charge the tws 4 times.
As Nuarl N6 pro become my no.1 favorite tws, I highly recommend it for people who is looking for audiophile quality sound in tws form factor.
