My MW08s came this morning and I've had a couple of hours with them at this point. The first hour was spent, as usual, tip rolling until I found what works best for me, which in this case are the XL Spinfit CP360s. The L included tips fit my left ear perfectly, but were too small for my right ear. The XL included tips were too tight on both ears and really stuffed up the sound. I also tried about five other likely tip candidates before settling on the CP360s. The fit is relatively shallow, but that gives the sound some room to breath and keeps the earphones comfortable. I'm definitely getting a good seal.
Sound-wise, these are like a warm hug. The sound is incredibly rich (without any bass-bleed), yet still nicely detailed (without any harshness). They're just right. I'm fine not having an equalizer included in the app, because I can't imagine I'd want to adjust the sound signature at all. My favorite TWS, sound-wise, has been the Jabra 85t, which I find a smidge better than the Sennheiser MTW (1st Gen). These MW08s are better. There's no issue with volume from my perspective. I'm listening now at about 45% on my iPhone, and it's louder than I need. One of my go-to songs to test new earphones is Eminem's "Love the Way You Lie." To be honest, I don't even like that song -- but it's got a couple areas (in both Eminem's and Rihanna's sections of the song) that are incredibly dense and complex "walls-of-sound" that all but the very best earphones completely fall down on. These earphones nail it. You can imagine how much I'm enjoying songs I actually like.
I haven't had an opportunity to test the ANC in real life. The NYC subway system is my go-to test bed, and I won't be on the subway until next week. Since they're a relatively shallow fit, my expectation is that they'll diminish the rumble of the subway (and even city traffic) -- hopefully sufficiently enough to allow me to enjoy some music on my way around town -- but I'm not expecting complete isolation. I can live with that. I DID test the ANC while sitting in front of my computer listening to YouTube videos of plane and subway noise. My preliminary reaction is that the ANC is -- about what I'd expect. It's not as strong as the Sony's or the APPs, but it makes a difference.
As reported elsewhere, the earphones are smaller than expected, and look terrific. There's no multipoint, or fast device switching, but you can hold the multi-touch button to switch devices. I read elsewhere some speculation that there was no Siri -- but there is. (Just hold the multi-touch button for three seconds.). And, by the way -- having physical buttons is fantastic.
A few odds and ends: I can confirm both AAC and aptX. (I returned the MW07+ because there was no AAC, and I'm glad M&W included it now.) I obviously haven't had a chance to test the battery yet, but if it's as advertised I'll be very happy. Finally, I updated the firmware upon opening. It took two tries on my iPhone 11 Pro Max, but eventually worked fine.
Bottom line: These are all about the sound, the battery life, and the design. If the intersection of those three things are what's important to you, these are as good as any earphones you'll find (at the moment). The ANC is an added bonus, but (as with most TWS), if you're looking for relative silence, you should probably look elsewhere.
