Now that I bought them, I'm sure reviews will be pouring out proclaiming MTW3 to be the best TWS ever, or for there to be a massive defect in the AZ60.
I did not get to listen to them yesterday and hope to do so today to finish up my thoughts on them. I'm WFH the rest of the month so I'm not getting my usual commute/break time every day to listen. Getting the SpinFit tips from Amazon today and I hope they're comfortable. One thing I'll say is that I'm finding the stock eartips a little uncomfortable. Going from Medium to Large helped a little (I'm a medium with all my other headphones, so this is odd), but so far, the Comply Sport 500s have felt even better. I have some AZLA Sednaearfit TWS (ML) tips and they're too shallow to be any good (also a very tight fit on the stem). Pulling the pieces out with the stock M tips also seems like the silicone eartips fold up a little and graze my ear canals on the way out. I think these may be sitting too deep in my ears and either the silicone is brushing against something, or the inside ends of the headphones are irritating my ears.
Definitely check the Bluetooth settings on your device (Settings>Bluetooth>tap whatever name the Tempotec show up as>look for LDAC option). I forgot this was an option under each device and just assumed the Technics app handled that. I believe I had to do this with my XM4 but Sony at least called out that step.
